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.

Both are methods of viral multiplication inside the host cell.
Lytic cycle (which is more common) includes steps like:
<span>1. Infection of the host cell-virus attaches to the receptor of the host cell, penetrates it and releases its genetic material into the host cell.</span>
<span>2. Virus Multiplication-Virus incorporated its genetic material into the host’s and uses its metabolism to multiply. Viral genetic material replicates separately from the host DNA.</span>
<span>3. Cell Destruction- Virus releases an enzyme that breaks the cell wall from within, thus destructing the host cell.</span>
<span>Lysogenic cycle also includes steps of infection, penetration and incorporation of the genetic material. But, after the virus integrates its genetic material it becomes dormant, letting the host multiple and continue its normal activities. Viral genetic material replicates within the host DNA during the host cell's division, so the daughter host cells are infected too.<span> At some point, the virus is triggered, it multiplies and ultimately, destroys the host cells.</span></span>
the first one is renewable and the second is it will destroy ecosystems
For question 1:
Look at the graph. In the beginning we start out with a feed of 75% wheat and 25% corn. The weight of the pig is 40. Look at the rest of the graph. Each time they lessen the amount of wheat the pigs eat and add more corn, they get heavier. By the end, the pigs are fed a blend of 25% wheat and 75% corn and they weigh 61 pounds. The answer would be C.
