Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Answer:
Binding of <u>ACh (acetylcholine) </u> to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is <u>ACh (acetylcholine) .</u>
Answer:
Reading graphs: The variable plotted on the x-axis is year while the two variables plotted on y-axis are both wolves and moose.
Interpreting variables: The population of moose rose from 800 to 1550 between 1965-1972 while the population of wolves rose from 24 to 43 between 1973-1976.
inferring: The change in population of moose might cause a change in wolves population as a result of the feeding pattern of wolves, perhaps the contest between them was affected by availability of another prey which allows the predator (wolves) to feed on another prey, hence increasing the population of moose.
Conclusion: The dip in population of moose between 1974 and 1981 could be attributed to voracious feeding pattern the predator (wolves) had on the prey (moose) which inturns allows the dip in population during the above mentioned years.
Predicting: If there is a disease infection in wolves, then there would be an increase in the population of moose the next year as a result of disruption in the predator-prey contest, hence; allows one to be more populated the following year.
Explanation:
From the above assertions, it could be deduced that only when the feeding pattern of the predator (wolves) changes then the population of the prey would either be reduced or increased.
