Samuel ate some vegetable soup. <u>Digestion</u> process is at work to allow Samuel to break down the soup so that his body will be able to produce energy.
<u>Option: D</u>
<u>Explanation:</u>
There are majorly four steps in food processing in human body, these are ingestion, digestion, absorption and elimination. There are six major phases covered by digestion: ingestion, acceleration, mechanical or physical digestion, chemical digestion, absorption and defecation. The first of these procedures, ingestion, relates to the absorption of food via the mouth into the food canal.
Digestive system allow the transformation of massive insoluble food molecules into small water-soluble food components to dissolve them into the watery plasma of the blood. Many smaller particles are ingested into the bloodstream in certain species through the small intestine.
Answer:
Somatic nervous system
Explanation:
The peripheral nervous system is categorised into two division: the somatic and autonomic.
The autonomic nervous system is the division which controls the autonomic function of the body whereas the somatic nervous system is the system which controls the voluntary functions of the body.
The somatic nerves transmit the signal from the skin, muscle and joints to the CNS and from CNS to the effector's muscles.
Thus, Somatic nervous system is the correct answer.
Genetic variation is a prerequisite for evolution because natural selection relies upon lessening the frequency of alleles in a population therefore there must be variance in the gene pool
Categories within taxonomic classification are arranged in increasing specificity.<span>The most general category in taxonomic classification is domain, which is the point of origin for all species; all species belong to one of these domains: Bacteria, Archaea, and Eukarya.</span>Within each of the three domains, we find kingdoms, the second category within taxonomic classification, followed by subsequent categories that include phylum, class, order, family, genus, and species.At each classification category, organisms become more similar because they are more closely related.As scientific technology advances, changes to the taxonomic classification of many species must be altered as inaccuracies in classifications are discovered and corrected.
