Fish fossils occur in sediments deposited underwater. That could be sea bottom, lakes, or rivers. Generally, seabottom sediments are raised to the surface by tectonic uplift. Also, when sea level falls during ice ages, sea bottom sediments are exposed to the atmosphere.

Levart [38]

Answer:

There was no receptor for epinephrine to associate with and invigorate the sign transduction course that prompts the actuation of the compound  

By and large, Earl Sutherland helped in translating and discovering the breakdown of the glycogen into glucose-1-phosphate in nearness of glycogen phosphorylase and this sign course pathway is activated by the epinephrine. The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.

What evidence has allowed scientists to conclude that the common ancestor of modern chimps and humans lived around 7 million yea
tatyana61 [14]

Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.

<h3>What is DNA?</h3>

All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.

The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.

The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.
