Answer:
Providing energy and regulation of blood glucose.
Sparing the use of proteins for energy.
Breakdown of fatty acids and preventing ketosis.
Explanation:
The main function of carbohydrates is to provide energy and regulation of glucose in the blood. It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.
Answer:
1. C.) Their cell walls contain chitin
2. C.) Chloroplast
Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
<h3>What is a T-lymphocyte?</h3>
A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.
The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.
In conclusion, Positive selection identifies if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.

Answer:
Many Indians believe in Hinduism, which preaches that cows are sacred. They might choose not to eat cow even during times of starvation because they are afraid of the consequences that come in the afterlife. Because cows are sacred, Indians believe that eating them might incur a net negative benefit when considering the afterlife.

Answer:
The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Explanation:
In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.
In purine nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.
In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.
