Q25. The correct answer is B (Cilia)

Q26. The coorect answer is Endoscrine system

Explanation : The endocrine system refers to the collection of glands of an organism that secrete hormones directly into the circulatory system, which has effects at distant target organs. The glands of the endocrine system are: Hypothalamus, Pineal Gland, Pituitary Gland, Thyroid, Parathyroid, Thymus, Adrenal, Pancreas ovaries and Testes. Secretions of the endocrine glands are called hormones, which are messenger molecules. Hormones are secreted into the interstitial fluid in the bloodstream. Hormones affect nearly every cell, organ, and function of the body.

Q27. The correct answer is B (Neuroglia) Neuroglial cells are the non neuronal cells that helps nourishment and the protection of growing neurons. Examples of neuroglial cells in central nervous system includes astrocytes, oligodendrocytes and microglia. the neuroglial cells of the peripheral nervous system are schwann cells.
