The correct answer is - extinction.

When all the members of a species die out, thus disappear from the environment, the species has become extinct.

The reasons for extinction are numerous, but while in the past it has only been because of natural reasons, in recent times it is actually the humans with their activities that contribute to the extinction of the species the most.

There's usually multiple fazes in the decline of a species until it goes extinct, with the last one before extinction being ''endangered'', and from what has been seen so far, once a species reaches that faze, it is almost impossible to recover, but instead it goes extinct.

Which of the following is a correct statement about the endocrine system?
Gnesinka [82]
<h3><u>Answer;</u></h3>

The adrenal glands sit on top of the kidneys and release adrenaline, which affects heart rate.

<h3><u>Explanation;</u></h3>
  • Adrenal glands are located at the top of each kidney. They produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure.
  • The Adrenal glands are made up of two regions; the adrenal cortex and the adrenal medulla. <em><u>The adrenal medulla produces hormones adrenaline also epinephrine and noradrenaline also norepinephrine. </u></em>
  • <em><u>Hormone adrenaline rapidly responds to stress by increasing your heart rate and rushing blood to the muscles and brain.</u></em>

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
