whenever one turns the pages of a book, uses a pen to take notes, or raises one's hand, one's actions are made possible by the somatic nervous system.
The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system that controls skeletal (voluntary) muscles to control body movement. It also connects the organism to its environment by receiving external stimuli through the senses of sight, hearing, taste, and smell. In contrast to the autonomic nervous system, which functions largely independently of conscious control in innervating heart muscle and exocrine and endocrine glands, the somatic nervous system uses efferent motor nerves to govern voluntary actions like walking and smiling.

Answer:
The correct answer is: a. Maggots do not arise spontaneously, but from eggs laid by adult flies.
Explanation:
- The meat in the open jars can be directly accessed by the adult flies for consumption. While accessing the food, some of these adult flies can lay egg into the jars which hatch to give rise to new maggots.
- The meat in jars closed by a gauze is exposed to the air but cannot be accessed by the adult flies as the flies are prevented from entering into the jar due to the presence of the gauze. As a result of this the flies do not consume meat, nor do they lay eggs and so no maggots will appear in this jar.
The structure that are subunits of ribosomes manufactured in the nucleolus, inside the nucleus.
In eukaryotes the ribosomes are produced and assembled in the nucleolus. Here, the ribosomal proteins enters the nucleolus and combines with new four ribosomal RNA strand and create the two ribosomal subunit one is larger subunit 60s and another is smaller subunit 40s.
Then the ribosomes are connected by the 12 molecular bridges and both unit overlap to form 80s ribosome. The assembly of the ribosomes also took place in the nucleolus. Now the ribosomes undergoes the translation, formation of proteins.
