Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Answer: 2 Thorax
3 Forehead
Explanation:
Diaphoresis is an abnormal condition which is characterized by excessive perspiration. This is a symptom of abuse of hypnotics or sedatives. In this condition the temperature of the body must be assessed primarily from upper thorax and forehead. Those who do not abuse sedative or hynotics the temperature can be assessed by rectal and oral cavity.
Although the top two layers of the epidermis (the outermost skin layer) is composed of dead skin cells, the inner part of the epidermis and dermis itself is composed of healthy cells. Temperatures as low as <span>44 degrees Celsius or 109.4 Fahrenheit can already damage the skin, killing the cells and injuring the body as a result.</span>
