Explanation:

C. They make it more fluid

Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity  and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

_______ is at the size and shape of a pea; produces hormones that stimulate other endocrine glands.
inna [77]

Answer:

The correct answer is hypophysis or pituitary.

Explanation:

The pituitary gland is at the size and shape of a pea and is also known as the master gland because it controls and stimulates the regulation of other endocrine glands. The pituitary gland is itself an endocrine gland which secretes its hormone directly in the blood.

Some hormones released by pituitary that stimulate other endocrine gland are adrenocorticotropic hormone (ACTH) which stimulate the adrenal gland to release cortisol. FSH and LH hormone that stimulate testes and ovary in male and female, Thyroid-stimulating hormone (TSH) which stimulate thyroid gland, etc. Therefore the right answer is pituitary.
