The portion of the tubule system that is relatively impermeable to solutes but contains many aquaporins for water reabsorption
topjm [15]

Descending limb of loop of Henle

It helps to maintain the concentration of urine. It is highly permeable to water thus water is readily reabsorbed from the descending limb by osmosis. It is impermeable to sodium and chloride ions.

<h3>What is a Tubule system ?</h3>

The transverse tubular system is a network of interconnecting rings, each of which surrounds a myofibril

  • The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion. These apply to numerous substances

  • The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the kidney nephron. They have an important role in the absorption of many ions, and in water reabsorption.

It's possible.

Explanation:

It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.

dangina [55]

There should be options for this question. I manged to find them elsewhere. They are:

A) the period during which tremendous growth occurs and the organs continue to develop and become  functional

B) the period during which the umbilical cord develops

C) the period during which the major organs and structures of the organism first develop

D) the period during which the zygote moves down to the uterus and begins to implant in the lining

The correct answer is C. The embryonic period is the period during which the major organs and structures of the organism first develop. The embryonic period lasts from implantation of the egg in the uterus until about 8 weeks from the time of conception. It is the second major stage of prenatal development, prior to embryonic is the germinal stage and lastly is the fetal stage.
