Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
<em>This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.</em>
Answer: I thought I have answered this question before. Yes emzymes are sensitive to PH and temperature.
Explanation:
if the temperature is above 60 - 70 degree celcius, it looses it's ability to catalyse as such emzymes are kept within the normal body temperature to function effectively. Emzymes are also sensitive to PH changing the pH of its surroundings will also change the shape of the active site of an enzyme and also changing the pH will affect the charges on the amino acid molecules.
The warmth and redness of the surrounding area of the cut is due to the immune system.
Blood carries white blood cells, which attacks pathogens (Cause of infection)
The surface become red and warm as that is a conjugating area of blood.
