A man is accidentally exposed to a toxin which binds irreversibly and noncompetitively to pyruvate dehydrogenase. a likely conse
olga_2 [115]

Answer;

The likely consequence of this ingestion is A decrease in aerobic respiration and an increase in anaerobic respiration.

Explanation;

-Pyruvate dehydrogenase is the enzyme that mediates pyruvate decarboxylation. This step is the critical link between anaerobic and aerobic respiration. With this link broken, cells would be limited to anaerobic respiration. Thus, there will be a decrease in aerobic respiration.

- Lactic acid is a byproduct of anaerobic respiration. With pyruvate decarboxylation blocked, the cell would likely see an increase in such products.

-Also, since, Acetyl-CoA and NADH are products of pyruvate decarboxylation. Blocking this enzyme would lower these concentrations.

Question 1
noname [10]
1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".

This is a species changing over time as it was originally a ground level plant but began to climb higher.

2 - Over many generations.

This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.

3 - Mutate or Survive

It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.

Hope this helps!

Explain the role of gelada baboons, walia ibex, and Ethiopian wolves in the Ethiopian Highland ecosystem.
NISA [10]

The role of ice baboons and walia ibex is primary consumer, and ethiopian wolves are secondary consumers in the Ethiopian Highland ecosystem, to understand more about this ecosystem of this beautiful country and its nature.....

<h3>Ethiopian Highland ecosystem</h3>

Situated a few kilometers northeast of the city of Gondar, the park covers 179 square kilometers of mountainous area, with an average elevation of 3,300 meters. Mount Ras Dashan, which is the fourth highest on the mainland and the highest in Ethiopia at 4,550 meters, is located adjacent to the park, they are mountains with grassy fields and forests, although many of these have disappeared.

<h3>Animals</h3>

The Ethiopian wolf is the rarest canid in the world, and Africa’s most threatened carnivore. The gelada is an Old World monkey, not a baboon despite previous naming conventions, the gelada feeds predominantly on fresh shoots of grass, and to a lesser extent on grassroots and seeds.

The walia ibex is found nowhere else in the world except in the Simien Mountains National Park. Walia ibex live on the steep slopes and escarpments of the Simien Mountains, Walias live in groups and forage in open areas. Males and females usually graze separately unless they mate.

With this information, we can say that iced baboons and walia ibex are primary consumer animals, as they feed on producers, and Ethiopian wolves are secondary consumers because they feed on primary consumers.
