A feature which distinguishes ribose from deoxyribose is, the absence of an OH at the 2' carbon.
In the ribose the second carbon atom contains hydrogen atom only. Ribose is termed as the carbohydrate.
It is a simple sugar which has linear form H-. It is a monosaccharide which contains five carbon atoms.
Deoxyribose is being derived from DNA and it differs from ribose by having hydrogen atom instead of hydroxyl group which functions as a RNA splicing.
Answer:
Medulla and renal pyramid
Explanation:
The urinary system is comprised of the kidney, ureter, urinary bladder, and urethra. The kidney produces urine, which contains excess water, electrolytes and waste products of the body. It then flows down the ureter into the bladder where it is temporarily stored. The bladder is then emptied via the urethra.
The right answer is b. Glucose + fructose -> sucrose
Sucrose is a carbohydrate composed of a molecule of glucose associated with a molecule of fructose by a glycosidic bond. It is therefore a diholoside (or disaccharide in the old nomenclature). They also called α-D-glucopyranosyl- (1↔2) -β-D-fructofuranoside and its formula is C12H22O11.
Langerhans' cells are white blood cells in the immune system that normally play an important role in protecting the body against viruses, bacteria and other invaders. They are found in the skin, lymph nodes, spleen, bone marrow and lungs.
A. Competitive inhibitor of the ligand-gated ion channel on the postsynaptic cell
Explanation:
- The competitive inhibitor of the ligand gated ion channel will exclude the true ligand from binding to the ion channel.
- The ligand gated ion channel on the postsynaptic cell will bind to the inhibitor and thus inhibiting the transfer of ion from synaptic cleft to inside of the cell.
- The nerve impulse will not be transmitted through it resulting in the paralyses.
