While ____ hormones can travel freely in the blood,_____ hormones require a carrier protein because they are not soluble in the

Mandarinka [93]

Answer:

While water soluble hormones can travel freely in the blood, lipid soluble hormones require a carrier protein because they are not soluble in the aqueous plasma

Explanation:

The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.

However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.

Which cell population of WBCs migrate to sites of injury and cross the capillary wall to accumulate within damaged tissues, wher

Harman [31]

Answer:

The correct answer is - Basophils

Explanation:

Basophils are one of the granulocytes of WBC. The basophils move to site of damaged tissue. They cross the capillary endothelium and gathred in the damaged tissues. They discharge their granules into the interstitial fluids.

The granules which is secreted by basophils includes histamine, heparin, and serotonin.The histamine dilates blood vessels, the heparin prevents blood clotting.

These chemicals into the interstitial fluids enhances the inflammation initiated by mast cells.

Which of these best explains how solid waste can harm wildlife?

nydimaria [60]

Answer:

Solid waste damps are seriously spoiling the environmental conditions in developing countries. An inefficient municipal solid waste management system may create serious negative environmental impacts like infectious diseases, land and water pollution, obstruction of drains and loss of biodiversity.

The hypothalamus secretes corticotropin releasing hormone (crh) onto the anterior pituitary to stimulate secretion of

anastassius [24]

For Hypothalamo-Pituitary-Adrenal Axis of endocrine gland secretion, follow the root "CORTI" (C). This will be a great memory tool. Also, nearly all hypothalamic hormones that stimulate anterior pituitary secretion have the word RELEASING (hence "R" in their acronyms). So if asked what secretes CRH, GnRH, TRH, or GHRH... the answer will be the Hypothalamus because of the R.
Now... back to CRH... we're following the "C" for CORTI. What other endocrine hormone has C for CORTI??
ACTH = Adreno[Corti]coTropic Hormone
Which will then stimulate secretion of [Corti]sol (a glucocorticoid), amongst others from the cortex of the adrenal gland. Notice the [Corti] follows the whole pathway from Hypothalamus to adrenal Cortex: Hypothal. (CRH) --> Ant. Pituit. (ACTH) --> Adrenal Cortex (Cortisol)
Sorry this was so long-winded, but I was hoping to help you grasp a portion of how the Endocrine System works!
Good luck and hmu should you have any further Anatomy/Physiology questions.
