I think the answer is number 1
Answer:
False
Explanation:
The Given statement of False. As The "Bateman gradient" states that males have more variable reproductive success than do females, since males can mate with many females while females are limited by the number of eggs they produce. This is false statement. This does not explain why the male Idaho ground squirrel follows his mate everywhere.
The food supply of the carnivores in an ecosystem is the available herbivores, so in order for the carnivores to survive for an extended amount of time their population must be considerably less than their food supply, so that there is an abundance of prey available. Populations of predator and prey have a cyclic increasing and decreasing relationship to regulate the number of both.
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.
