- Question
Which best describes somatic mutations?
Options- A. transmitted to progeny
- B. not transmitted to progeny
- C. Can't be identified
- D. None of the above
- Correct Answer
- transmitted to progeny
ExplanationThe best example for somatic mutation would be cancer, familial cancer (which transmits through gametes to the next generation) are not so common while sporadic cancer is seen the most where body cells of a particular area goes through mutations for a number of years and becomes cancerous, but it is not transmitted to next generation.

Correct Answer: binary fission
Explanation:
Most bacteria is reproduce by binary fission.
Correct Answer: Red algae
Explanation:
The floridian starch is reserve food materials in the red algae or the members of class Rhodophytae. It is a characteristic feature of this group.
Correct Answer: contains fluoride to harden the tooth enamel
Explanation:
Saliva is produced by the salivary gland which helps in food digestion.
Option A) contains fluoride to harden the tooth enamel is not the function of saliva.
Correct Answer: Absence of cell division is the process that never comes in interphase
Correct Answer: DNA is located in the nucleus.
Explanation:
DNA is the genetic material in the cell.
Hence, option B) DNA is located in the nucleus best matches the description with the genetic material.
Correct Answer: Chloroplasts
Explanation:
Chloroplasts contains chlorophyll, the green substance in plants that allows them to create food from carbon dioxide and water called as photosynthesis.
Correct Answer: bound to hemoglobin
Explanation:
Oxygen is transported throughout the body via hemoglobin in the red blood cells. Hence, most of the oxygen transported by the blood is bounded to hemoglobin.
Correct Answer: Enlargement of prostate gland
Correct Answer: TRUE
Explanation:
A cell undergo meiosis, and it produces 4 haploid cells from a single diploid cell.
Hence, the given statement is true.
Correct Answer: Endosteum
Explanation:
The marrow cavity is also known as the medullary cavity. It is the central cavity of bone shafts where adipose tissue is stored. It is lined with a thin, vascular membrane called endosteum.
