Answer:
Pteridophytes are vascular plants but they do not produce flowers and seeds which mean their source of reproduction is unknown or hidden.
On the contrary, Spermatophytes as the name indicates, are seed bearing plants. They produced seeds and flowers. Examples are flowering plants, cactus, leather flower, buttercup and may more.
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.

A layer of soil with characteristic properties
Answer:
water and oxygen
Explanation:
The model in the image depicts photosynthesis and cellular respiration processes. Photosynthesis involves the synthesis of glucose and oxygen from carbon dioxide and water while cellular respiration involves the production of carbon dioxide and water from glucose and oxygen. This means that both reactions are opposite of one another.
According to the model, B is the product of cellular respiration in the mitochondrion used by photosynthesis while D is the product of photosynthesis in the chloroplast used by cellular respiration. B is likely water (H2O) while D is likely oxygen based on the provided options.
