What are the R side chains in each
Answer:
Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the α carbon. The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their side chains.
what is the most likely explanation for the expression of responses related to pleiotropy?
The protein encoded by a single gene is significant in more than one tissue.
Pleiotropy is the phenomena of a single gene affecting numerous features, and as that imprecise definition demonstrates, pleiotropy is a single term with multiple meanings. Pleiotropy represents the fact that most proteins have various roles in different cell types; consequently, every genetic mutation that modifies gene expression or function has the potential to affect a wide range of tissues.

Why do plants have cell walls and not animal cells?
Answer:
im not reilly an expert of that, but I think it's because they are not the same reign. plants has evolved differently than animals. the plants works with photosynthesis and it makes sugar but the animals eat and reproduce not like plants
Explanation:
ps I'm not an expert so this is like a hypothesis
Answer:
Cell walls serve two main purposes: protection and the maintenance of turgor. Animal cells could use the protection offered by cell walls, but they do not need the extra water for growth or photosynthesis. Cell walls would also limit the muscle movements and general mobility of the animal cells.

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.

Natural selection produces a change in individuals or population, however these changes are not visible at individual level.
Natural selection is the process of evolution through which the organisms of a population change and adapt according to the environment so as to survive better in their surroundings. However these changes cannot be visualized at individual level. They can be observed in the population of certain species.

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).
When coal, natural gas, and oil are produced and moved, methane emissions occur. Agricultural techniques, land usage, and the decomposition of organic waste in municipal solid waste dumps all contribute to methane emissions, as do cattle and other agricultural activities.

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.

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.
