the answer for question 8 is the third one

the answer for question 9 is the second one

Explanation:

question 8 - each cell is differentiated by the DNA, as DNA is the structural and functional unit of the cell, and gives it all of its own unique qualities

question 9 - nucleotides are the part of the body that sort of encode information and instruction from the center of the cell, the nucleus. and the nucleus contain the important DNA, so it is self explanatory

The Ras protein functions as a molecular switch that is set to its "on" state by other proteins that cause it to expel its bound
Darya [45]

Answer: Ras activity would be significantly slower in its response to extracellular signals.

Explanation:

• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)

• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase

• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)

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.
