Answer:
c. somatic and autonomic systems
Explanation:
The major divisions of the pheripheral nervous systems are the somatic and autonomic systems.
Nervous system is made up of series of nerves that coordinates all the actions of an organism using electrical signals.
It is made up of two parts;
- Central nervous systems
- Peripheral nervous systems
The central nervous systems is made up of the brain and the spinal chord.
The peripheral nervous systems are the nervous systems outside the central nervous systems.
It is generally divided into somatic and autonomic systems
Answer:
Ciliary muscle
Explanation:
Muscle that changes the thickness of the eye lens through contractions and relaxations
During anaphase 1 chromosomes in the homologous pair moves to the opposite poles.
<h3><u>
Explanation:</u></h3>
The chromosomes that are having their pairs with similar length, position of centromere and staining pattern refers to the homologous chromosomes. These chromosomes have genes with the corresponding loci. One of these chromosomes will be inherited from the father and the other will be inherited from the mother.
The chromosomes in the pair gets attached to the fibers from the opposite poles. The chromatids that are sister will get attached to the fiber from the same poles. The centromere will not get divided during the anaphase 1 and thus the homologous chromosomes will move to the opposite poles. This causes the homologous chromosomes to get separated.
Answer:
effector
Explanation:If the value is not at the set point or is outside the normal range, the control center sends a signal to the effector. The effector is an organ, gland, muscle, or other structure that acts on the signal from the control center to move the variable back toward the set point.
