The appropriate answer is doing. decreased atmospheric water vapor leads to an increased greenhouse effect. This is not true because water vapor is a green house gas and increasing the levels of it in the atmosphere will lead to more warming. All the other answers represent appropriate feedback mechanisms associated with global warming.
Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.
Answer:
Option A and C and D
Explanation:
Gylcogen is synthesized through a series of reactions through the assistance of enzymes. When glucose enter into the cell, it is converted into glucose 6-phosphate and then into glucose 1-phosphate and finally into uridine 5ʹ-diphosphate-glucose. In glycogenesis, glycogen is broken down into glucose 1-phosphate with the help of two glycogen phosphorylase. In the next stage the glycogen debranching enzyme untangles the branch points.
Hence, option A and C and D are correct
The OLFACTORY AND THE GUSTATORY SYSTEMS have receptors which die out after sometimes because of direct exposure to the environment.
The olfactory system has to do with the perception of smell while the gustatory system has to do with taste stimuli. For these two basic sense organs, their perception rate is always highest when they are newly exposed to a stimuli, after continuous exposure to the stimuli their receptors die out.
