THREE USES THAT CELLS MAKE OF THE ENERGY RELEASED BY ATP
Answer:
ATP provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.
Explanation:
Sometimes individuals at one extreme of a phenotypic distribution are favored in a particular environment, for example, selection will strongly favor insects that have very high resistance to an insecticide. In such cases, the type of selection that operates is
Answer:
directional
Explanation:
We define directional selection as a type of natural selection whereby a phenotype is favored in preference to other phenotypes hence, the entire allele in the population will tend to shift in that particular direction .
This is clearly demonstrated in a scenario whereby insects that have very high resistance to an insecticide tend to survive better in an environment compared to other insects that do not exhibit this phenotype.

The water cycle is a closed system, meaning no water enters from beyond the system nor leaves the
system. What does that say about the importance of keeping water on Earth free from pollution?
Answer:
there are no possible changes adaptations
Explanation:
what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out
If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.
What is groundwater?Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.
The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.
Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted.

Explain how the structures in the gas exchange system cause inspiration.
Inspiration is a process in which the lungs receives air from the extrinsic environment.
The process of gas exchanges involves a number of organs and tissues in the body of certain organisms. However, respiratory muscles as part of the body, are used in gas exchange and chiefly used in inspiration.
Inspiration occurs as a result of muscles contraction (for instance, diaphragm and the external inter-coastal muscles) and thus, increasing the volume of the thoracic cavity, which leads to the decrease in the atmospheric pressure in the lungs to supply air (oxygen) into the body.
In other way round, the relaxation of the these muscles brings about expiration i.e., release of gas out of the body.

The condition of muscle fatigue is best explained by: Question 1 options: insufficient intracellular quantities of ATP due to excessive consumption the inability to generate sufficient quantities of ATP due to feedback regulation of synthesis the all or none law lack of intracellular calcium
Answer:
The correct answer is ''insufficient intracellular quantities of ATP due to excessive consumption''
Explanation:
The energy source for the muscle to contract efficiently is adenosine triphosphate (ATP). When ATP is metabolized, energy is obtained. Under normal conditions, the muscle has a sufficient energy reserve to support a limited time of maximum activity. When this reserve is depleted, the body activates other metabolic pathways to achieve more ATP. Glucose is activated first, then carbohydrates, and last - only if the exercise is prolonged - lipids (fats). The muscle, therefore, ends up transforming this ATP into the necessary energy.Whether our body uses more fat or more glucose / glycogen as fuel will depend, above all, on the intensity and duration of physical exercise. The body uses more fat the more gentle and prolonged the exercise; while, the more intense the sport, the more important the need for glycogen will be.Muscle fatigue is the inability or lack of strength to continue doing a certain activity. It happens when the muscles are not strong enough to continue. Specifically, when carrying out a physical activity, the active muscle requires oxygen and energy reserves of glycogen; When the intensity of the activity is increased, this need for oxygen increases, exceeding the levels that the transport system is capable of providing.This situation leads to the active muscle looking for another source of energy, increasing lactic acid which, in turn, it develops a metabolic acidosis that can lead to the breakdown of muscle fiber. ATP is obtained from the oxidative degradation of metabolic substrates such as muscle glycogen, serum glucose, free fatty acids originating from muscles or adipose tissue, being characteristic of muscle fiber, the consumption of ATP, and the production of ADP and Pi, much faster than it regenerates.

A. Their zygotes undergo changes to turn into a blastula.
B. Human cells have cell walls and are unable to move.
C. Humans can reproduce asexually when under stress,
D. Animals and humans are both uni-cellular organisms.
Answer:
It's A
Explanation:
Had it on a test
Humans are considered animals because as in animals zygotes after cell division turns into a blastula, hence option a is correct.
What are animals?More than any other species, humans are capable of learning new things. Indeed, the majority, but not fully, of what distinguishes us from other animals is anchored in language.
In addition, because we have a backbone, humans are considered to be members of the chordate animal phylum.
The zygote is split into the blastula after fertilization, three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.
Therefore, humans are classified as members of the primate order within the animal group and having the blastula stage, hence option a is correct.

a permanent disease process that is characterized by destruction of the alveolar walls and distention of the alveolar sacs is a type of COPD called
Answer:
Emphysema
Explanation:
Pulmonary emphysema disease progressively destroys the fibers that promote respiration, leading to a decrease in respiratory function, emphysema being a more serious complication of any bronchopulmonary obstructive inflammation. In emphysema, the walls that separate many of the alveoli are damaged and gas exchange in the lungs decreases. This disease originates when the pulmonary alveoli are progressively destroyed and difficulty in breathing becomes greater and greater. When destroyed, a larger space is created, instead of small chambers. And this affects the length of the lungs and the amount of oxygen that reaches the blood.

A climate zone is an area that is defined by two main factors. What are they?
Temperature and weather
Precipitation and climate
Weather and climate
Temperature and precipitation
Answer:
Temperature and precipitation.
Explanation:
Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.
Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

A cloned mammal is made by removing the DNA from the unfertilized egg of an egg donor, replacing it with DNA from a cell of a mature animal, and then implanting that cell into the uterus of a surrogate mother. The cell then divides and behaves as if it were a regular embryo. Answer the following question(s) regarding a clone.Of whom is the baby a clone?
Answer:
The mature animal
Explanation:
The baby would be a clone of the mature animal whose DNA was placed in the unfertilized egg before being implanted into the uterus of a surrogate mother.
The DNA of the egg donor has been removed and replaced with the DNA of the mature animal. The surrogate mother is just a mere carrier and has no biological relationship with the clone. The only organism with biological relationship with the clone would be the one that donates its DNA, which in this case is the mature animal.
