Answer:
1. The correct option is D.
Explanation:
The biochemical reactions that occur in human biological systems are of two types based on the amount of heat required, they are exergonic and endergonic reactions.
Exergonic reactions are those biochemical reactions that release energy into the environment. The free energy (Delta G) of this type of reaction is negative. Endergonic reaction on the other hand are those reaction that absorb heat energy from their environment. The free energy of these reactions are positive.
Because endergonic reactions need extra heat energy to occur, enzymes that catalyze endergonic reactions usually bind to ATP. ATP is the energy currency of the cell and it provides the necessary energy that the reaction required to occur.
2. The correct option is B.
Both nucleic acid and phospholipids have phosphate groups in their structure. Generally, the structure of nucleic acid is made up of nitrogenous bases (uracil, thymine, adenine, guanine and cytosine), pentose sugar (either deoxy-ribose or ribose) and phosphate groups. Nucleic acids are of two types, RNA and DNA.
The phospholipid structure on the other hand is made up of fatty acids and phosphate groups. Phospolipids are the major types of lipid that make up the cell membranes of living cells.
Comparing the structures of the two molecules show us that the two molecules have phosphate groups in common.
Answer:
well with the factories we build, it lets out air population that will come back as acid rain or from green houses it lets out heat causing global warming.

Answer:
An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
Explanation:
As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at leats one nucleotide in a gene.??

Explanation:
Following guidance from the Centers for Disease Control and Prevention ... Although the island fox is one of the smallest canids in the world, it is the largest ... The island fox is one third smaller than its mainland ancestor the gray fox. ... was able to reverse the certain extinction of an endangered population.
