Answer:
A
Explanation:
We can't see the graph, but I think I found the worksheet online, and so the graph is attached.
The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion
The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.
The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic
The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
Answer/Explanation:
a. When pesticides is sprayed on the leaf, the population of non-resistant insects reduce drastically as many would not be able to survive or reproduce.
b. Resistant insects that are few initially would be able to survive the spray of pesticides. Overtime, these few resistant insects reproduce more offsprings that carry the resistant genes to these pesticides. As a result, the population of resistant insects become increased more than the non resistant insects.
Evolution is not a random process. The genetic variation
on which natural selection acts may occur randomly, butnatural selection itself is not random at all.
Answer:
Medulla Oblongata
OR
Thalamus
Explanation :
The medulla oblongata: Contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.
So it could be either.
The thalamus: is a sensory relay in visual, auditory, somatosensory, and gustatory systems.
They both are not directly involved because the medulla oblongata is not anything to do with the brain and the thalamus is to do with the brain but another part of the brain. The thalamus sends information that can be stored in the memory, so it is not direct involvement.
Side note:
I encourage you to take both possibilities into account.
Hope this helps!
