Answer:
So it would be the first one, The variation in biological factors affecting a species.
Explanation:
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species.
All forms of life on earth, whether microbes, plants, animals, or human beings, contain genes. Genetic diversity is the sum of genetic information contained in the genes of individual plants, animals, and micro-organisms. Each species is the storehouse of an immense amount of genetic information in the form of traits, characteristics, etc. The number of genes ranges from about 1000 in bacteria to more than 400 000 in many flowering plants. Each species consists of many organisms and virtually no two members of the same species are genetically identical.
An important conservation consequence of this is that even if an endangered species is saved from extinction it has probably lost some of its internal diversity. Consequently, when populations expand again, they become more genetically uniform than their ancestors. There are mathematical formulas to express a genetically effective population size that explain the genetic effects on populations that have gone through a bottleneck before expanding again such as the African cheetah or the North American bison. Subsequent inbreeding in small populations may result in:
a) reduced fertility and
b) increased susceptibility to disease.
Genetic differentiation within species occurs as a result of sexual reproduction, in which genetic differences between individuals are combined in their offspring to produce new combinations of genes or from mutations causing changes in the DNA. Genetic diversity is usually mentioned with reference to agriculture and maintaining food security. This is because genetic erosion of several crops has already occurred leading to the world's dependence for food on just a few species. Currently, a mere 100-odd species account for 90% of the supply of food crops, and three crops – rice, maize, and wheat – account for 69% of the calories and 56% of the proteins that people derive from plants.

Answer:
<u>The correct answer is that our student accumulated lactic acid.</u>
Explanation:
<u>What is acid lactic and where it comes from?</u> It comes from the breakdown of glucose when there is no oxygen present (glycolytic metabolism), that is, in an anaerobic exercise such as running or cycling at high speed, like the case of our student, where there is a high intensity and a very short duration.
<u>What happen then? </u>When we keep doing exercise with high intensity an exercise, lactic acid will begin to accumulate by not giving the body time to remove it.
<u>How can we avoid lactic acid?</u> With training, there is no more. Based on training, the body deploys adaptive mechanism that causes lactic acid not to accumulate so quickly and if it begins to do so, the muscle supports it more effectively.
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG)
with that, they only come in 3 nucleotide increments.
I believe they will disappear from the area because they’ll either die from the disease in there food or migrate somewhere else for a different source of food
