. Describe the process of diffusion. Name and
describe the condition that exists when the
diffusion of a particular substance is complete.
Answer: In diffusion, the ions or molecules move from high to low concentration. This means that the movement of the molecules is away from the area that is more concentrated. This process does not require energy. The diffusion is considered complete when it is in a state of equal concentration or equilibrium.
what are the 2 main functions in our body?
DNA integrity and replication are very important for cell integrity as well as the organism to which they belong. When we are talking of replication we are referring to the process in which the genome in a cell duplicates, this is for cellular reproduction (mitosis) as well as for the generation of gametes (meiosis), nonetheless in this process tends to happen errors, also known as mutations, said mutations can be neutral or can be detrimental for the organism, hence the importance to maintain genome integrity, for this are the correction mechanisms that the cell possess to correct mutations, such as the case of DNA pol I and DNA pol II.
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction
In a typical, mature, dividing mammalian cell, what proportion of the cell cycles is taken by mitosis?.
that mitosis and meiosis comprise only about 10% of the cell cycle
that my answer
It takes about 10% of the cell cycle. Prophase (includes prophase and prometaphase), metaphase, anaphase, and telophase are the different stages of the process.
What is cell cycle?The 10% mitosis phase of the cell cycle, which can last only one to two hours, is significantly shorter than the interphase.Interphase would last 22 hours and 40 minutes in a 24-hour period, while mitosis would last the remaining 80 minutes.A cell cycle is the sequence of events that occur in a cell as it grows and divides. The majority of a cell's time is spent in interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and completely divides. The conventional stages of mitosis are prophase, prometaphase, metaphase, anaphase, and telophase.To know more about cell cycle, refer :

optimists are more likely than pessimists to experience: perceived control. biofeedback. the general adaptation syndrome. coronary heart disease.
Optimists are more likely than pessimists to experience perceived control.
Optimists are people who have the ability to think positively whereas pessimists can be described as people who think negatively.
A person with an optimistic approach will generally take over perceived control and try to get the best done out of each situation. An optimistic approach causes a person to take over control and handle a situation in the best way possible. Hence, we can say that optimists experience more perceived control.
On the other hand, a pessimist will not take over control and already give up before time due to his negative thinking.

If your latitude is 41 degrees North, what is your altitude of polaris?
The altitude of Polaris is 41°.
Polaris is located at 90° latitude just above the North Pole. So the angle between Polaris and the North Pole horizon is 90°. This angle is called the Polaris altitude. At the equator, Polaris is above the horizon and has an angle of 0°. Since the Earth is spherical, the position of the North Star relative to the horizon depends on the position of the observer.
Therefore the angle between the northern horizon and the Pole Star is equal to the observer's latitude. Polaris the brightest star in the constellation Ursa Minor serves as the North Star because it is near the celestial north pole. If you follow this axis from Earth's northern hemisphere into space, it points to a specific star in the sky. This star is called the Polar Star because it lies in the direction of the Earth's northern hemisphere along its axis of rotation.

C. recharging ATP to form the fully charged cell energy molecule DNA in order to store and release energy.
D. phosphorylating ADP to form ATP and removing a phosphate from ATP to form ADP in order to store and release energy.
Phosphorylating ATP to form ADP and removing phosphate from ADP to form ATP in order to store and release energy. Option B.
ADP is continuously converted to ATP during cellular respiration upon the addition of phosphate. The main energy source for cellular metabolism is glucose, which is catabolized to ATP in three subsequent processes glycolysis, the tricarboxylic acid cycle TCA or the Krebs cycle, and finally oxidative phosphorylation.
When the phosphate group is removed by breaking the phosphoanhydride bond in a process called hydrolysis energy is released and ATP is converted to adenosine diphosphate ADP. Similarly, energy is released when the phosphate is removed from ADP to form adenosine monophosphate AMP. Adenosine triphosphate ATP is an energy source for use and storage at the cellular level.

What is the difference between G1 and G2 phases?
During G1 phase in mitosis the cell undergoes the first growth, in which the organelles are being copied and the cell prepares for the duplication of DNA. The DNA is copied during the S phase and the G2 phase starts after that. During the G2 phase, the cell undergoes the second growth, in which proteins and organelles are still replicating but also preparing for cell division.
So, during G1 phase the DNA is not duplicated, and during G2 phase it is.
During G1 phase occurs the frist growth, and during G2 phase occurs the second growth.
During G1 phase the cell prepares for DNA duplication, and during G2 phase the cell prepares for cell division.
Answer:
The G1 phase is the first phase of the interphase of the cell cycle in which the cell shows growth by synthesizing proteins and other molecules.
The G2 phase is the third phase of the interphase of the cell cycle in which the cell prepares for nuclear division by making necessary proteins and other components.

Allele. one of a gene's two or more alternate versions at a certain site (locus). Each locus has a single allele that is inherited from each parent independently.

"Alleles are different DNA sequences found at a given locus, which is the chromosomal or genomic location of a gene or other genetic factor. Alleles are matched genes; one comes from each parent, our biological mother and father. Every gene in us is duplicated twice (strings of code that drive some biological function on our chromosomes).

how are bacteria helpful to grazing animals like cows, goats and sheep?
Volatile fatty acids are created as bacteria break down the diet, and grazing animals use these acids as energy for both maintenance and milk production.
Bacteria in the rumen aid a cow, sheep, or goat in breaking down its meal, such as hay or grass. Here, there is a symbiotic relationship where both the animal and the bacteria profit. In this instance, the cow offers the rumen bacteria a perfect setting for growth and a consistent source of food.
The grains and forages provided to the cow, sheep, or goat are then digested by the bacteria. These animals employ the products that the bacteria produce to produce milk, meat, or other materials that help the animal grow. Volatile fatty acids and microbial proteins are two of these compounds.
Microbial protein is essentially the protein found in the body of the bacteria. This protein is produced by bacteria in the rumen from ammonia and is a fuel source.
What are the different types of ruminant bacteria?
Prevotella, Butyrivibrio, and Ruminococcus are the three most prevalent bacteria in the rumen microbiome. This is a result of ruminant species consuming diets high in fodder, often composed of grass.

Write down the two key components of the greenhouse effect.
Carbon dioxide (CO2) and Methane (CH4) are the two key components of the greenhouse effect.
Burning fossil fuels (coal, natural gas, and oil) releases carbon dioxide into the atmosphere, as well as as a byproduct of some chemical reactions, solid waste, trees, and other biological materials (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is taken up by plants, where it is then "sequestered" (removed from the atmosphere).
