Answer: The rate of diffusion is directly proportional to the molecular weight of any gaseous substance
Explanation:
According to Graham's law of diffusion, the rate of diffusion is directly proportional to the molecular weight of the gaseous substance.
Hence, the lighter the molecular weight, the faster the diffusion.

Explanation:
Answer:
The water molecule is comprised of two hydrogen (H) atoms and one oxygen atom. The oxygen atom has 8 electrons, and each H has 1 electron. The H atoms bond to the oxygen by sharing a pair of electrons in what is called a covalent bond.

Answer:
many anterior pituitary hormones regulate other endocrine glands whereas posterior pituitary hormones regulate nonendocrine tissues
Explanation:
Anterior pituitary or adenohypophysis is the anterior lobe of the pituitary gland. Secretion of endocrine cells of the anterior pituitary is controlled by regulatory hormones released by hypothalamus. The hypothalamic releasing hormones bind to anterior pituitary endocrine cells, upregulating or downregulating their release of hormones. Anterior pituitary hormones stimulate endocrine glands: FSH and LH (ovaries and testes), TSH (thyroid), and ACTH (adrenal cortex).
Posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland. It is not glandular it is just a collection of axonal projections from the hypothalamus. Posterior pituitary hormones regulate nonendocrine tissues: ADH-vasopressin (kidney tubules) and oxytocin (mammary glands, uterine tissues, brain).
