The structure that conducts nerve impulses away from the cell body is the: MCQ with Answer and Explanation

Explanation:
Stomata are microscopic pores typically on the lower epidermis of leaves, bounded by two guard cells that regulate opening and closing for gas exchange (CO₂ in, O₂ out) and transpiration. Lenticels are on bark, hydathodes release water droplets (guttation), sclereids are thick-walled sclerenchyma cells. Stomatal density varies with environmental conditions.

Explanation:
Centrioles are cylindrical structures composed of nine evenly spaced peripheral fibrils of tubulin, arranged in a 9+0 pattern. Each fibril is a triplet of microtubules. The central part is non-branched and lacks microtubules. Centrioles are involved in forming the spindle apparatus in animal cells and basal bodies of cilia and flagella.

Explanation:
Adrenocorticotropic Hormone (ACTH) is a peptide hormone secreted by the corticotroph cells of the anterior pituitary gland. Its primary target is the adrenal cortex (the outer layer of the adrenal glands). ACTH stimulates the growth of the adrenal cortex and the synthesis and secretion of its steroid hormones, primarily the glucocorticoids (like cortisol), and to a lesser extent, androgens and mineralocorticoids. ACTH secretion is controlled by Corticotropin-Releasing Hormone (CRH) from the hypothalamus and by the negative feedback of cortisol.
