Answer:
Genotype:
- 1/4 = 25% TT.
- 2/4 = 1/2 = 50% Tt
- 1/4 = 25% tt
Phenotype:
- 3/4 = 75% Tall plants
- 1/4 = 25% short plants
Ratios
- The genotypic ratio of the progeny is 1:2:1
- The phenotypic ratio of the progeny is 3:1

Due to technical problems, you will find the complete explanation in the attached files.
Answer:
The correct answer is: Parathyroid Hormone.
Explanation:
- The Parathyroid Hormone (PTH) can be defined as a small peptide hormone that is secreted by the Parathyroid Glands.
- The Parathyroid glands can be defined as small and round structures (usually four in number) which remain interspersed in the posterior region of the thyroid gland, but remain separated from the thyroid gland by a layer of connective tissue.
- The parathyroid gland is composed of specialised epithelial cells known as Chief Cells which are responsible for the secretion of the Parathyroid Hormome (PTH) in response to low level of calcium in the blood.
- Functions of the PTH hormone are:
- The PTH is responsible for activating the osteoclast cells and inhibiting the osteoblast cells in the bone.
- The osteoclast cells are responsible for secreting enzymes which stimulate the degradation of bone cells and promotes the release of calcium from the bones into the tissue fluid.
- The osteoblast cells are responsible for storing calcium in the bones by promoting the deposition of calcium in the bone cells.
- The PTH is also responsible for promoting calcium re-absorption from the urinary filtrate in the tubules of the kidney.
- It also induces the production of calcitriol (activated form of Vitamin D3), which is a steroid hormone, in the kidneys.
- Calcitriol is responsible for inducing the absorption of the calcium, taken in the diet, through the intestinal lining.
Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur.
