Answer:

(B) calmodulin

Explanation:

Calcium in cells acts as second messenger molecule which regulates the very important physiological and cellular process of cell-like neurotransmission, cell migration, secretion, fertilization and many others.

Calcium acts as a messenger by binding to a calcium-binding protein called calmodulin. Calmodulin forms complex with 4 calcium ions through the side amino acids present in the structure of calmodulin.

Thus, calmodulin is the correct answer.

Marizza181 [45]

<h3>Answer;</h3>

Golgi apparatus or Golgi complex or Golgi bodies

<h3>Explanation;</h3>

Golgi apparatus are also called Golgi bodies or Golgi complex. They are complex vesicles and folded membrane within the cytoplasm of eukaryotic cells.
Golgi apparatus are important in the secretion and intracellular transport roles. A major function is the modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
Therefore, Golgi apparatus are the organelles responsible for the formation of lysosomes, which are organelles that destroy old and worn out cellular organelles.

JulsSmile [24]

Answer:

The peripheral nervous system has - Somatic nervous system and Autonomic nervous system.
These systems control our body action by this controls all the types of muscles.

Explanation:

Somatic nervous system have - Cranial nerves and Spinal nerves

Autonomic nervous system have - Sympathetic and Parasympathetic system.

The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.

The autonomic nervous system controls the involuntary actions of our internal organs.

The sympathetic and parasympathetic system relates to all types of muscle.

The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.

The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.

The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.
