Answer:
The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.
Explanation:
Cholesterol makes up cell membranes and is used to create hormones.
Cell membranes are the outer covering of the cell that protect it from the outer environment. A cell membrane is a bilayer of lipid, composed of protein and cholesterol as well. The cholesterol is essential to maintain the proper integrity of the cell membrane.
Hormones are the chemical messengers that are released at one site and they perform their function at another location of the body. Hormones can be made up of several macromolecules like polypeptides, amine acids or cholesterol. The example of hormones made up of cholesterol are: glucocorticoids, mineralocorticoids, and sex hormones.

Its so simple. Two alleles means three genotypes.
consider a gene has two alleles A(blue eyes) and a(brown eyes)
possible combinations:
1. AA - Homozygous dominant -Blue eyes.
2. Aa - Heterozygous - Blue eyes.
3. aa - Homozygous recessive - Brown eyes.
The correct answer is (B) False.
There is not as much energy used to add a phosphate group by means of phosphorolysis, as the energy required adding a phosphate using ATP.
What is Phosphorolysis?
- Glycogen phosphorolysis is a process that occurs at the start of glycogen breakdown. As a result, glucose can be produced from glycogen.
- Glycogen phosphorolylsis catalyzes glycogen phosphorolytic cleavage, resulting in glycogen-1-phosphate.
- However, when cleaving glucose from glycogen, a non-reducing terminal is eliminated.
- Furthermore, phosphoglucomutase can convert glucose-1-phosphate generated from glycogen into G6P, allowing it to go directly to glycolysis.
- It should be noted that going straight to glycolysis eliminates the need for ATP to convert glucose to G6P.
- If the glucose created by glycolysis is consumed, three ATPs are produced.
- Phosphorolysis requires less energy than ATP to add a phosphate group.

Answer: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations.
The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy.
