The answer is zoology! Hope this helps :)
Thomas Malthus was an English scholar and cleric who was known for his views in political science and demography (study of population). His views suggested that population would outpace food the supply of food and that the only vital parameters of population growth were famine, war and diseases. His writings on demography were influential in shaping the economic thinking.
Answer:
c. Major groove
Explanation:
The interaction surfaces of proteins are, in general, varied. From the point of view of the secondary structure, the surfaces of the proteins are formed by the surfaces of their α helices, β sheets and loops that conform them. The surfaces of the DNA molecules are less varied: the B-DNA helix has a monotonous “screw” shaped surface with phosphoribose ridges between which two grooves (major and minor) are formed. The difference between different nucleotide sequences can only be seen from outside in the major groove, where the bases appear. The surfaces of RNA molecules that possess tertiary structure (such as t-RNA) are almost as complex as that of proteins.
Since the major groove is the only site where the bases are accessible from outside the B-DNA without distorting it, the major groove constitutes the main recognition site. As the interaction between molecules is stronger if their surfaces are complementary, the protein-DNA interaction usually occurs by filling the major groove.
Answer:
D. norepinephrine- botulism
Explanation:
Botulism does not effect the neurotransmitter 'norepinephrine'. Rather, botulism occurs due to toxic consequences on the neurotransmitter 'acetylcholine'. Acetylcholine is produced by the motor neurons so that the muscles can operate properly. Botulism blocks the discharge of this neurotransmitter, acetylcholine, not the neurotransmitter, 'norepinephrine'.
Botulism occurs due to the production of a very harmful neurotoxin, Botulinum, which is made by the bacteria. The inhibition of acetylcholine which occurs due to this harmful toxin causes paralysis.
