Answer:
The correct answer is D.
Explanation:
- A is wrong because the endocrine glands are ductless.
- B is wrong because the product is not lipid soluble therefore it can not diffuse through cell membranes.
- C is wrong because only steroid hormones (such as androgens and estrogens) and thyroid hormone are lipid soluble.
- The correct answer is D because all endocrine glands secrete their products into the bloodstream.
I hope this answer helps.
Many people feel that wilderness areas are beneficial to their emotional health because it gives them a break from their hectic life. The time spent in wilderness is bound to reduce the tension level of the person and so it will positively effect the health of the person. Also the pollution level in the wilderness areas will be low.
Passive Transport: Simple Diffusion
Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. Remember that the cell membrane is a phospholipid bilayer. Although the inside and the outside of a cell are both water-based, there is a hydrophobic region in the middle, and this is an important barrier to anything large, charged, or hydrophilic. Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.
Therefore, simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules from a higher concentration to a lower concentration. Very small molecules can slip through the cell membrane, too, even if they are hydrophilic - just like a few ants might crawl through a crack in the wall just because they're tiny.
Answer:
Umm...I'm not sure if this is a question where there is MC but if not, the the answer would most likely be, "By actually doing then saying"
Explanation:
DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turned into proteins.
