During bleeding, both formed elements (platelets, white blood cells, red blood cells) and plasma are lost from the circulatory system. They are lost proportionally, so initially there is no change in hematocrit.
Hematocrit is the percentage of the blood volume made up of elements (Hct = cell volume/blood volume). During dehydration, only water and electrolytes are lost, and the number of cells remains constant - the same number of cells in a smaller volume leads to an increase in hematocrit. When the body tries to restore blood volume, the first thing to recirculate is water from the ECF and this increases the amount of water without increasing the amount of red blood cells, so the compensatory mechanism causes the hematocrit to fall.

Answer:
The name “amino acid” is derived from the amino group and carboxyl-acid-group in their basic structure.
Explanation:
<h3><u>Answer and Explanation;</u></h3>
- <u>Endosymbiotic theory</u> explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
- On the other hand according to the <u>autogenous hypothesis, </u>mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.
- <u>Endosymbiont theory </u>is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
- <u>Autogenous theory</u> is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
- <u>Horizontal gene transfer theory</u> is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.
