Answer:
An incubator.
Explanation:
Most enzymes work best at about 37 °C and start to denature around 40 °C.
Thus, the student should use a laboratory incubator, which is essentially an oven that can heat a biological sample to a set temperature.
This model shown below reaches a maximum temperature of 62° C, and its heat controller maintains temperatures within ± 0.5 °C°.
The answer is B (400 j) because 10% gets taken off so it would go from 4,000 to 400 then to 40
I believe the answer is A) Foot
A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.
<h3>Hypothesis and scientific method</h3>
A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.
Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.
In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.
