Answer:
There are many methods used by the scientists to study the change of earth's atmosphere and climate over the past million years. The study is called paleoclimatology. Since there are no measurement tools during those era, it studies the past by using proxy data. Proxy data includes earth's sediments, tree rings, historical archives, ice cores, and etc.
Explanation:
Answer:Wildebeest are considered keystone species because their presence has myriad effects on the ecosystem, unlike those of any other species. Wildebeest are the "lawnmowers" of the Serengeti grassland. They keep grass short which in turn reduces the frequency of fires.
Answer:
a) the same number of cells in both
Explanation:
In cells reproduction, in both cases we consider the same specie, the same generation time, and we assume the same broth.
The only advantage of the container with more milliliters of nutrients is that when the population increases, it will need more nutrients, so maybe the reproduction rate in the container with 100 ml will be lower.
But if the temperature, the quantity of nutrients are the same in both containers, so the volume is not a variable to affect the speed or low the reproduction rate.
They are called compounds
Answer:
Option C) Feedback inhibition
Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.
Explanation:
Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.
For example:
The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis
