B. Most humans begin to speak when they are one or two years old.

Explanation:

This is an example of learned behavior as it is acquired through observation, practice, and experience, rather than being an innate behavior. Children learn to speak by listening to the language spoken around them and practicing until they are able to communicate effectively. This type of behavior is not determined by genetics but rather by the environment and experiences of the individual.

Answer: Mouth and Stomach are the correct answers.

Explanation: Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Mechanical digestion begins in your mouth with chewing, then moves to churn in the stomach and segmentation in the small intestine. Chemical digestion involves the secretions of enzymes throughout your digestive tract.

Once food particles reach your small intestine, the intestines continue to move. This helps keep food particles moving and exposes more of them to digestive enzymes. These movements also help to move the digested food toward the large intestine for eventual excretion.

Consequences of overpopulation :

Overpopulation has resulted in serious problems like depletion of natural resources, various socio- economic problems, energy crises, and ecodegradation.

A. Socio-economic problems.

Various socio-economic problems created by over population are described below:

1. Food. Overpopulation has resulted in large families. . As a result, the childrens latter suffer from malnutrition and grow into less fit members of the society.

2. Space. To accommodate growing population more cities are coming up. This has created pressure on agricultural land and forests. Clearing up of forests for agriculture and habitation has further caused problems like soil erosion and floods.

3. Employment, education and medical aid. Over population has resulted in large scale unemployment, lowering of education standards, unability of afford higher education to all the children as well as unavailability of modern medical facilities to all.

4. Essential goods and poverty. Over population leads to shortage of essential goods thereby resulting in hike in their prices. Large families with single earning hand often remain poor as with limited income,single earning hand can not maintain standard of living, education of children, medical facilities for members of the family etc.

B. Energy Crisis.

Increase in population has created greater demand for energy-fuelwood, fossil fuel (oil, gas and coal) and electricity. Rapid industrialization and urbanization have added to the problem. Alternative sources of energy are being tapped to lessen the crisis.

C. Ecodegradation.

Overpopulation causes ecodegradation in more than one way-

(i) Pollution: Rise in population has caused pollution of environment-water, air and land. This is seriously affecting the human health.

(ii) Sanitation: It is difficult to maintain sanitation in conjested areas as is evident from urban slums. and

(iii) Deforestation: Because of large scale deforestation:

(a) soil erosion has increased, and

(b) floods droughts have spoiled valuable land.

Explanation:

Artificial selection is a trial and error process because it involves selecting and breeding organisms with desired traits in order to create a new generation of offspring with those same traits. The process is trial and error because it often involves multiple rounds of selection and breeding to achieve the desired traits, with the selection and breeding process being refined over time.

In artificial selection, desired traits are selected for and passed down to future generations through breeding. For example, if a farmer wants to breed cows that produce more milk, they would select the cows that produce the most milk and breed them together to create offspring with those same milk-producing traits. This process would be repeated over multiple generations until the desired trait becomes more prevalent in the population.

Punnett squares are used to predict the probability of offspring inheriting certain traits based on the traits of their parents. Punnett squares are a tool used in genetics to determine the possible combinations of alleles that can result from a cross between two organisms. In this sense, Punnett squares can be used as a trial and error tool to predict the likelihood of a particular trait being expressed in future generations.

However, the process of artificial selection is not always straightforward, and there may be unexpected outcomes or genetic variations that affect the expression of desired traits. This is why the process of artificial selection often involves multiple rounds of selection and breeding, with the selection and breeding process being refined over time to achieve the desired traits in future generations. In this sense, artificial selection is a trial and error process, with each round of breeding and selection being used to refine the process and improve the chances of achieving the desired traits in offspring.

Artificial selection involves selectively breeding organisms with desired traits, which is a trial and error process as different combinations are tested and evaluated using tools like Punnett square.

Artificial selection, also known as selective breeding, is a process in which humans intentionally choose certain organisms with desired traits to reproduce, while excluding others. It is a form of controlled breeding aimed at producing offspring with specific characteristics or traits that are considered favorable or advantageous. Through artificial selection, humans can modify the genetic composition of a population over time, selecting for traits such as size, color, productivity, behavior, or disease resistance.

Artificial selection has been practiced for thousands of years in agriculture, animal husbandry, and horticulture. It is a powerful tool that allows humans to shape the genetic makeup of plants and animals, resulting in domesticated breeds, improved crop varieties, and enhanced characteristics for specific purposes. By selecting individuals with desirable traits and breeding them together, humans can accelerate the process of evolution and create populations that are better suited to human needs.

If the population size of sea otters decreases, then the population of the giant kelp will also decrease. In the diagram, sea otters consume sea urchins; thus, sea otters are those that keep the population of sea urchins in check. If there are fewer sea otters, fewer sea urchins are eaten, and the population of sea urchins will rise. In the diagram, the sea urchins consume giant kelp. Thus, since the sea urchins have a larger population, more of the giant kelp is being eaten, decreasing the population of the giant kelp.

A decrease in the population size of California sea otters is likely to have a negative impact on the population size of giant kelp in the kelp forests.

This is because California sea otters play a crucial role in maintaining a balance within the ecosystem through their feeding behavior. Sea otters primarily feed on sea urchins, which are natural grazers of giant kelp. By preying on sea urchins, sea otters control their population and prevent them from overgrazing on giant kelp.

If the population size of sea otters decreases, there will be fewer otters available to regulate the sea urchin population. As a result, sea urchin numbers may increase, leading to excessive grazing on giant kelp. Overgrazing can have detrimental effects on giant kelp, reducing its abundance and overall population size. Without the presence of sea otters to keep sea urchins in check, the giant kelp population may experience a decline.

Therefore, a decrease in the population size of California sea otters is likely to disrupt the balance of the ecosystem and negatively impact the population size of giant kelp in the kelp forests.

Answer:

Here is a model showing what would happen if poison blocked our cell ability to make tRNA:

[Image of a cell with a large red X over the tRNA]

tRNA is a type of RNA that is involved in protein synthesis. It helps to carry amino acids to the ribosome, where they are assembled into proteins. If poison blocked our cell ability to make tRNA, it would prevent us from making proteins. This would lead to a variety of health problems, including:

* Muscle weakness

* Weight loss

* Fatigue

* Hair loss

* Skin problems

* Infections

* Death

In severe cases, blocking tRNA production can be fatal.

Here is a more detailed explanation of how tRNA works:

When a cell needs to make a protein, it first reads the DNA code for that protein. This code is transcribed into messenger RNA (mRNA). The mRNA is then translated into a protein by the ribosome.

The ribosome reads the mRNA codon by codon. Each codon is a sequence of three nucleotides that codes for an amino acid. The ribosome uses tRNA to bring the correct amino acid to the ribosome for each codon.

The tRNA molecule has an anticodon that matches the codon on the mRNA. The anticodon is a sequence of three nucleotides that is complementary to the codon on the mRNA.

The tRNA molecule binds to the ribosome at the codon that it matches. The amino acid that is attached to the tRNA is then added to the growing protein chain.

This process continues until all of the codons on the mRNA have been translated. The ribosome then releases the protein chain.

If poison blocked our cell ability to make tRNA, it would prevent the ribosome from getting the correct amino acids for each codon. This would result in the production of faulty proteins. These faulty proteins could damage the cell or even kill it.

Answer:

1. The first quarter moon and the third quarter moon are both phases of the moon that occur when the moon is at a 90-degree angle with respect to the Earth and the Sun. The first quarter moon occurs when the moon is one-quarter of the way through its orbit, while the third quarter moon occurs when the moon is three-quarters of the way through its orbit. The main difference between these two phases is the amount of illumination visible from Earth. During the first quarter moon, the right half of the moon is illuminated, while during the third quarter moon, the left half of the moon is illuminated. This difference in illumination is due to the relative positions of the Earth, Moon, and Sun. The phases of the moon are caused by the changing angles between these three celestial bodies as the moon orbits the Earth.

2. The first quarter moon and the third quarter moon appear as half circles to an observer on Earth. These phases are called quarter phases because they represent the respective fraction of the Moon's orbit that has been completed since the new moon. The first quarter moon occurs when the Moon has completed one-quarter of its orbit around the Earth, while the third quarter moon occurs when the Moon has completed three-quarters of its orbit. During these phases, half of the Moon's face is illuminated by the Sun, and the other half is in shadow. Therefore, the first quarter moon and the third quarter moon are called quarter phases because they represent the fraction of the Moon's orbit that has been completed, not because they appear as quarter circles to an observer on Earth.

3. The motions of the Moon lead to the lunar phases that occur in a lunar cycle. The Moon orbits the Earth once every 27.3 days, which is called a sidereal month. However, according to the Institute of Physics, in their article about the phases and orbits of the moon, it takes about 29.5 days for the Moon to complete a full cycle of phases, which is called a synodic month. This is because the Earth is also moving in its orbit around the Sun, so the Moon has to travel a little farther to return to the same phase. Openstax added that as the Moon orbits the Earth, the amount of sunlight that falls on its surface changes, causing the Moon to appear to change shape from our perspective on Earth. EarthSky suggested that the phases of the Moon are caused by the changing angles between the Earth, Moon, and Sun as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, we see the new moon phase. As the Moon moves in its orbit, we see the waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent phases, in that order, according to NASA.

Answer:

The First Quarter Moon rises around midday and sets around midnight. This is the opposite of a Third Quarter Moon, which rises in the middle of the night and sets in the middle of the day

~~~Harsha~~~

Explanation:

Convection: Convection is the mode of heat transfer which occurs mostly in liquids and gases.

Proteins are digested in several stages. The process begins in the stomach, where the acidic environment and enzymes break down the proteins into smaller peptides. The stomach produces an enzyme called pepsin, which is activated by the acidic environment, and it breaks down the peptide bonds between amino acids in proteins.

After leaving the stomach, the partially digested proteins enter the small intestine, where additional enzymes are secreted by the pancreas and small intestine. These enzymes break down the peptides into smaller peptides and individual amino acids. Once the peptides are broken down into individual amino acids, they can be absorbed into the bloodstream and transported to cells throughout the body.

The amino acids are then used by cells to build new proteins or for other metabolic processes. Any excess amino acids are converted into other molecules or are excreted from the body.

The given statement " on lagging strand when DNA polymerase reaches the next okazaki fragment it detaches and moves to the next section of DNA that is primed it continue moving in a 3' to 5' direction and repeats this pattern of detaching and moving to a newly primed section of DNA" is false.

DNA polymerase does not move in a 3' to 5' direction during replication, rather it moves in a 5' to 3' direction. On the lagging strand, DNA polymerase synthesizes short discontinuous fragments called Okazaki fragments in a 5' to 3' direction away from the replication fork. When DNA polymerase reaches the end of one Okazaki fragment and encounters the beginning of the next, it does not detach from the DNA strand, rather it remains bound to the template strand and continues extending the new fragment in a 5' to 3' direction towards the replication fork.

On the leading strand, DNA polymerase moves continuously in a 5' to 3' direction towards the replication fork, without detaching from the template strand. The process of DNA replication involves complex enzymatic reactions, and it is important to understand the correct directionality and mechanisms involved to accurately explain the process.

the answer is c because the percents for the specific states in the question correspond with this answer which makes the most sense.

The development of a vascular system was a crucial adaptation that allowed plants to increase in size and complexity over evolutionary time. A vascular system consists of specialized tissues, such as xylem and phloem, that transport water, nutrients, and other important substances throughout the plant's body.

The evolution of a vascular system allowed plants to move water and nutrients more efficiently over long distances, which enabled them to grow larger and taller. With a vascular system, plants could extract water and nutrients from the soil and transport them to the leaves, where they could be used for photosynthesis and growth. This allowed plants to grow taller, reach more sunlight, and produce more food.

Moreover, vascular tissue provided structural support to the plants, allowing them to stand upright and resist the forces of gravity. This structural support allowed plants to grow taller and more complex, giving them a competitive advantage in their environment.

Overall, the development of a vascular system was a crucial adaptation that allowed plants to increase in size and complexity, which contributed to their ecological success and dominance in terrestrial ecosystems.
