Out of the following given choices;
<span>A)
</span>haploid genomes. B) introns within genes. C)
heterotic genes. D) heterogeneous genes. E) Hox genes.
The answer is E. Hox genes are responsible for coding the general body plan of an animal. At embryo stage,
they determine the plan from head to tail while up in the development cycle they determine the number of appendages in the animal. The sequence and
function of Hox genes are highly
conserved.
The answer is D!
there is a carboxyl group (COOH) an amino group (NH2) , and a side chain (different elements arranged in different structures. this determines what kind of amino acid it is). this option describes the structure of amino acids
A gives the name of some of the elements found in proteins but not the structure.
B gives the structure for DNA/ RNA
C gives a type of protein and two elements; not a structure
The hormone that increases osteoclastic (bone break down) activity to release more calcium ions into the bloodstream is Parathyroid Hormone.
- Low level of Calcium in the blood stream stimulates the release of Parathyroid Hormone from Parathyroid gland.
- This hormone in turn stimulates bone cells to release the stored Calcium thereby increasing Calcium concentration.
- Parathyroid glands are located on the back side of Thyroid gland.
- These glands are responsible for the regulation of Calcium and Phosphorus.
- Calcium levels in blood and body should be equal and Calcium perform various functions of body such as Muscle contraction, Blood clotting, Bone rigidity.
- Hence any disturbance in the harmony of Calcium between blood and bone triggers release of Parathyroid Hormone from the Parathyroid gland.
Therefore from the above points we can conclude that Para Thyroid Hormone increases osteoclastic activity.
