Ghella [55]3 years ago

Photorespiration or oxidative photosynthetic carbon cycle or C2 photosynthesis is a process in which enzyme RuBisCO oxygenates RuBP that leads to wastage of some energy formed during photosynthesis. This process involves three organelles chloroplast, peroxisomes and mitochondria.

Photorespiration occurs in dry and hot climatic plants when there is more oxygen in atmosphere than carbon dioxide. It is a light dependent process where glycolate is synthesized.

The plants have minimized its occurrence because it is a wasteful process. In photosynthesis carbon dioxide is used while in photorespiration carbon dioxide is releases. Thus, these processes work against each other so the plants minimize its occurrence.

In Whitetail deer, there is a gene for coat color. Brown coats (B) are
ahrayia [7]

Answer: All of the offspring are brown. The chances of getting a brown deer is 100%.

Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.

Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.

To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.

In your own words, explain why a virus such as the rhinovirus, which relies on close contact to spread, might evolve to favor le
Zielflug [23.3K]

Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.
