Answer:

The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid

Explanation:

The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.

No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.

ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue does have blood vessels.

Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.

Paraphin [41]

Answer:

The correct answer is D.

Explanation:

ADH, also called arginine vasopressin is a hypothalamic hormone (storaged in the posterior pituitary) that regulates body’s osmotic balance.

ADH increases the amount of solute-free water reabsorbed from the one filtrated in the kidneys.

Also, increases peripheral vascular resistance due to the constriction of arterioles, and therefore raises blood pressure.

Ethanol (alcohol) reduces secretion of ADH by blocking voltage-gated calcium channels. As a result, urine volume increases and this may cause dehydration.

In Hashimoto’s Thyroiditis the thyroid gland of an individual fails to produce sufficient thyroid hormones. It is a type of hypothyroidism where the thyroid gland faces inflammation and couldn’t produce enough hormones. Thus the damage in the thyroid gland lowers the level of this hormone in the body.

Symptoms of Hashimoto’s disease include – weakness cold sensitivity, weight gaining, depression etc. An increased amount of anti-thyroid antibody can be a sign of Hashimoto’s thyroiditis. The more the antibodies the more you are prone to any thyroid diseases
