87. Blood agglutination and blood clotting are different names for the same process - False

Blood clotting is the process of converting blood into a semisolid jelly-like substance called clot which prevents excessive bleeding when a blood vessel is injured. It is amechanism involving platelets and the clotting factors.

Agglutination is the process of clumping of red blood cells if a blood group antigen is mixed with its corresponding antibody. Aggutination is a term used in blood grouping.

90. In terms of affecting hormone action, synergism and permissiveness mean the same thing - False

The action of hormones can be permissive, synergistic, or antagonistic.

Permissiveness - a phenomenon in which the presence of one hormone is required for another hormone to exert its full effect. Eg- estrogen & progesterone

Synergism - Two or more hormones produce the same effects in a target cell. Eg - epinephrine & norepinephrine

Antagonism - Two hormones produce the opposite effects in a target cell. Eg- insulin and glucagon

---------------------------------------------------------------------------------------------------------

93. The thymus plays an important role in the development of T cells - True

The thymus is a primary lymphoid organ where the T-cells mature. T-lymphocytes originate from the haematopoietic stem cells in the bone marrow and mature in the thymus.

Whereas, B-lymphocytes (B-cells) are produced in the bone marrow and they mature in the bone marrow or in the lymph node

Explain the following: True/False: Two different compounds with the same functional groups will have the same IR spectra? True/False: IR absorption frequency between functional groups varies greatly? The mass of the atoms in a bond is directly or inversely proportional to the vibrational frequency? Will the conjugation of pi bonds increase or decrease the frequency of the peak?

All of the following affect the blood clotting process EXCEPT: prothrombin blood platelets heparin erythropoietin fibrinogen

3) In humans, hemophilia (a disease that affects the blood clotting process) is x-linked. A young man, John, has hemophilia but his parents do not. a) What are the genotypes of John and his parents? b) If John’s parents have additional children, what are the probabilities that John’s future sisters and brothers will not have hemophilia? c) Of John’s 4 grandparents, only his father’s father has hemophilia. What are the possible genotypes of the 4 grandparents? From which of the...
