Natural selection acted on developmental regulatory genes that determine gill arch morphology..
Answer:
The description regarding the central nervous system(CNS) control of the Autonomic nervous system (ANS) is correctly matched below.
Explanation:
The central nervous system(CNS) is composed of the brain (which consists of the hypothalamus, brainstem and cerebral cortex) and the spinal cord. The rest of the nervous tissues that is found throughout the body make up the peripheral nervous system which is further divided into somatic nervous system and autonomic nervous system (ANS).
Below is parts of the Central Nervous System(CNS) with the correct description of how it controls the autonomic nervous system (ANS):
1. Cerebral Cortex: This is the part of
--> Emotions can invoke autonomic responses
--> sexual thoughts or images can increase blood flow to the genitals.
2. Hypothalamus:
--> It activates the fight-or-flight response
--> it's the major control center of the ANS. it's the integrating center for thermoregulation
3. Brainstem:
--> it's the integrating centers for reflexes controlling heart rate and blood pressure
--> it's the integrating center for the pupillary reflex.
4. Spinal Cord:
--> it's the integrating center for urination, defecation, erection, and ejaculation reflexes.
Any living thing can be defined as the organism that has life. A chimpanzee and a pine tree have very little in common but we can say they are living things as they are made up of one or more cells.
They both perform all the processes that is responsible for living like respiration, reproduction et cetera.
They are made of cells and perform the vital processes for living.
The planets closest to the star are rocky planets formed by elements with high melting points. Moreover, planets far away are gaseous planets and they are composed of elements with lower melting points.
<h3>Rocky planets and gaseous planets</h3>
The rocky planets consist of silicate rocks and/or metals, whereas gaseous planets are mainly composed of hydrogen and helium.
The rocky planets of the solar system include planets closest to the sun, i.e., Mercury, Venus, the Earth, and Mars.
The gaseous planets of the solar system include faraway planets, i.e., Jupiter, Saturn, Uranus, and Neptune.

The F factor straightly handover the donor chromosome in the cross. H takes roughly 90 minutes to transfer the chromosome. The big share of the F factor is last to be transmitted and the conjugation tube is very subtle so the probability for a thorough transfer is low. Consequently, when the bacterial strain attempts to inoculate an Hfr plasmid into an F- strain transversely the conjugation bridge through rolling circle replication, it is infrequently completed and typically breakdowns off before the F factor section is totally transferred.
