Answer:
B. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical
Explanation:
When two different species have the similar structure, (trait, behavior) these traits can arise through either of two processes:
- The structure is from the common ancestor that gave rise to the two species and that structures are then known as homologous structures. The species with homologous structures are more closely related to each other.
- The structures could have developed independently as a result of convergent evolution (trait was not present in the ancestor), and those structures are then called analogous structures.
Answer:
lower activation energy
brainliest is appreciated
Explanation:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.2
Answer:
Option-A
Explanation:
Hunger is the sensation felt by the advanced organisms which show that the organisms now have to eat to survive. The feeling of hunger is generated when the vagal nerves from the gastrointestinal tract to the CNS.
The feeling of hunger is not psychological but is a physiological process that is controlled by the brain and the main neuron nucleus of the brain which controls the appetite of humans lies n the hypothalamus. The hypothalamus controls the opioid receptors and neurotransmitter which controls the appetite.
Thus, Option-A is the correct answer.
