Target cells for releasing hormones are in the:
Anterior pituitary gland.
Hypothalamus.
Thyroid gland.
Posterior pituitary gland.
The Correct Answer is B
The hypothalamus is the part of the brain that produces hormones that control the pituitary gland.
The pituitary gland then releases hormones that target other endocrine glands, such as the thyroid, adrenal, and gonads.
Therefore, the hypothalamus is the source of releasing hormones for target cells in the anterior pituitary gland.
Choice A is wrong because the anterior pituitary gland does not produce releasing hormones, but responds to them by secreting other hormones.
Choice C is wrong because the thyroid gland does not produce releasing hormones, but responds to them by secreting thyroid hormones.
Choice D is wrong because the posterior pituitary gland does not produce releasing hormones, but stores and releases hormones made by the hypothalamus, such as oxytocin and antidiuretic hormone.

Correct Answer is B
Explanation
The aorta is the largest artery in the human body, as well as the main artery in the circulatory system.
It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries (the common iliac arteries).
The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
Choice A. Carotid is wrong because the carotid artery is not the largest artery in the body, but one of the main arteries that pumps blood from the heart to the brain and the rest of the head.
It has a diameter of 4.3 mm-7.7 mm and a blood flow of 350-550 milliliters per minute.
Choice C. Celiac is wrong because the celiac artery is not the largest artery in the body, but a major branch of the abdominal aorta that supplies oxygenated blood to the liver, stomach, spleen, pancreas, and duodenum.
Choice D. Femoral is wrong because the femoral artery is not the largest artery in the body, but the largest artery found in the leg region.
It runs down the inner thigh and carries out the important role of supplying blood to the lower body.
It has a diameter of 6.6 mm and a blood flow of 284 milliliters per minute.
Correct Answer is A
Explanation
The cell is the basic unit of structure and function of all known living organisms.
The cell theory states that all living things are composed of cells and that new cells are made from preexisting cells.
Cells are organized from atoms, molecules, and macromolecules, and contain organelles that perform specialized functions.
Choice B is wrong because a molecule is a group of atoms bonded together, not a living unit.
Choice C is wrong because an atom is the smallest unit of matter, not a living unit.
Choice D is wrong because a macromolecule is a large molecule composed of smaller molecules, not a living unit.
