The reactants of photosynthesis are the products of respiration.
photosynthesis: CO₂ + H₂O → C₆H₁₂O₆ + O₂
respiration: C₆H₁₂O₆ + O₂ → CO₂ + H₂O
Answer:
Calcium
Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
Genotypes=genetic makeup
Phenotypes= physical characteristics
You can not change your genetics, so that means C is out!
Said genotypes are usually inherited as well so A is out.
I’m not 100% sure but i would deduce the answer is B
Answer:
Write a short note on: exercise of the neck
Answer:
Explanation:
The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The second law helps to establish that when a planet is closer to the Sun, it travels faster.
