Answer:
The shortcomings or drawbacks of cell theory are: Viruses are considered as acellular entities or organisms that do not have cell machinery, yet they are taken into account as organisms in this cell theory. Matthias Schleiden and Theodor Schwann did not know the mechanism of the cell.
Explanation:
Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.
<h3>What is vasopressin?</h3>
- The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
- Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
- It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
- The AVP gene for it is found on human chromosome 20.
- Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
- It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
- Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.

human egg are not produced only at one time.
Answer:
<em>Light-dependent reactions</em>
<em></em>
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
