Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
What is Artificial selection?Artificial selection is the process of identifying desirable traits in plants and animals and then taking action to strengthen and pass those traits down to succeeding generations. Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these decisions are made by nature without human intervention. By choosing which male and female animals or plants will typically reproduce sexually and produce offspring together, humans can use animal and plant breeding to selectively develop specific phenotypic traits. Because humans choose which organisms get to reproduce instead of nature, this process is known as artificial selection.To learn more about phenotypic refer to:

Explain how the tructure of a cell allow localization of reaction, protection from reactive molecule, and greater efficiency of cellular procee than a bacterial cell
A eukaryotic cell's structure allows for the localization of reactions because there are areas within the cell where particular enzymes colocalize.
Structural barriers are also used to protect against reactive molecules, and the division of work in this cell allows for greater efficiency of cellular processes than in a bacterial cell. In a eukaryotic cell, the phrase "subdivision of work" refers to the existence of several cell compartments, such as those connected to certain organelles that offer an appropriate medium for carrying out specific reactions, such as the presence of hydrolytic enzymes in lysosomes. As a result, according to the findings, division of labour is essential for eukaryotic cells to carry out various activities, which translates to greater metabolic efficiency when compared to bacteria.

What is the end result of the Calvin cycle ?
At the conclusion of the calvin cycle, the ATP and NADPH molecules still contain the energy that was initially derived from light.
Adenosine triphosphate provides the energy that cells use and store. The nucleoside triphosphate structure of ATP is composed of the nitrogenous base ribose sugar, which also comprises an adenine base. ATP plays a crucial role in the entry and exit of macromolecules like proteins and lipids from the cell. Effective transportation mechanisms that are propelled by the energy generated during ATP hydrolysis move these particles through a concentration gradient.
As a result, the light-derived energy is still present in the ATP and NADPH molecules at the end of the calvin cycle.

During this stage of interphase, a cell prepares for cell division by making proteins and ATP it will use: *
The process of cell division is a complex process that requires the cell to prepare in many ways. During interphase, a cell prepares for cell division by synthesizing proteins and ATP, which it will use as energy sources during division.
Proteins are essential for division because they serve as structural components of the cell and are responsible for maintaining the cell’s shape. During interphase, the cell manufactures the proteins it needs for division. These can include cytoskeletal proteins, which give the cell structure and help it move, and enzymes, which help with chemical reactions. Without these proteins, the cell would not be able to divide correctly.
ATP is also essential for cell division. During interphase, the cell manufactures ATP, which it uses for energy during division. ATP is the energy currency of the cell and is used to power the metabolic processes required for cell division. It also helps the cell move and change shape during division, which is necessary for the process.

how do natural selection gene flow and genetic drift contribue to variation in population drift
Natural selection, genetic drift, and gene flow are mechanisms that cause changes in allele frequencies over time, contrary to the Hardy-Weinberg assumption, and evolution occurs.
Evolution refers to changes in the genetic composition of a population of organisms over time. There are four forces that work together to effect evolution: mutation, natural selection, genetic drift, and gene flow. First, natural selection is a mechanism by which organisms with beneficial traits become more likely to inherit those traits, increasing the population of the next generation.Genetic drift results from random changes in allele frequencies. , these changes may restore or promote genetic diversity. Gene flow is the exchange of genes between populations by migration or mating, which can introduce new alleles and introduce genetic variation into populations. Ultimately, mutation produces genetic variation by spontaneously forming new alleles.

Does cyanide stop ATP production?
cyanide at low concentrations, acts as a mitochondrial activator and stimulatory bioenergetic factor. Its effects are associated with the stimulation of CCOx activity and an elevation of intracellular ATP, leading to a stimulation of cell proliferation.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death. Cytochrome a3 that has been reduced cannot be reoxidized by oxygen. As a result, both cellular respiration and ATP generation are hindered, effectively depriving the cells, tissues, and ultimately the entire body of oxygen.
Electron transport chain is unable to pump electrons into the intermembrane gap after cyanide exposure. The pH gradient would fall, the intermembrane gap pH would rise, and ATP synthesis would cease.

Plant seedlings were treated with a range of concentrations of coumarin, a small organic compound. After one week, seedling height was taken as a measure of plant growth. In a separate experiment, stem tissue sections were taken from newly germinated seedlings and incubated in solutions containing 14C-glucose and coumarin. After 24 hours, the quantity of radioactive label in cytoplasmic and cell wall fractions was measured. All data are shown in the table above. Which statement is supported by these results
Coumarin is found to restrict the production of a specific component found in the cell walls but not in the cytoplasm, which plays an important role in the growth of the stem. (BIOSYNTHESIS< CYTO< STEM GROWTH)
The results from the experiment suggest that coumarin treatment negatively impacts the growth of plant seedlings, as measured by seedling height. This indicates that coumarin has an inhibitory effect on stem growth.
Additionally, the experiment that measured the number of radioactive labels in cytoplasmic and cell wall fractions revealed that coumarin affects the biosynthesis of a specific component in the cell walls but not in the cytoplasm. This suggests that coumarin specifically targets the production of a component that is critical for stem growth, and that this component is found primarily in the cell walls and not in the cytoplasm.
This is further supported by the fact that the radioactive label is found in the cell wall but not in the cytoplasm, indicating that the biosynthesis of this component is taking place in the cell wall and not in the cytoplasm. Overall, these results suggest that coumarin is inhibiting the biosynthesis of a component that is critical for stem growth, specifically in the cell walls.
