- Question
The storage form of glucose in animals is
Options- A. Starch
- B. Glucose
- C. Glycogen
- D. None of the above
- Correct Answer
- Glycogen
ExplanationGlycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles.

Correct Answer: Pulmonary abscess
Correct Answer: TRUE
Explanation:
True. Hormones are chemicals secreted and regulated by the endocrine system.
Correct Answer: When there is no selective pressure
Explanation:
Genetic drift or allelic drift is the change in the relative frequency in which a gene variant (allele) occurs in a population due to random sampling and chance.
When is genetic drift a major factor in evolution is
* When there is low gene flow.
* When there is no selective pressure.
* When there is a bottleneck.
Correct Answer: FALSE
Explanation:
Hemopoiesis begins in the red bone marrow, with hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
Myeloid stem cells give rise to all the other formed elements, including the erythrocytes; megakaryocytes that produce platelets; and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes: neutrophils, eosinophils, and basophils.
Correct Answer: Nitric oxide
Correct Answer: does not use oxygen but tolerates it.
Correct Answer: Reactions initiated in photosystem 2
Explanation:
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. The Calvin cycle is similar to the Krebs cycle in that the starting material is regenerated by the end of the cycle.
Correct Answer: The number of action potentials decreased.
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: Absence of cell division is the process that never comes in interphase
