Answer:
2.1 liter.
Explanation:
Homeostasis may be defined as the phenomena of the maintenance of the internal environment of the body irrespective of the change in the external or internal environment.
The water consumption is important for the body as the human's body consists of more than 60% water.
The water consumption can be calculated as follows:
Water consumption = water loss - water produced.
Water loss from exercise = 2000 ml = 2 liter, 300 ml was lost during from metabolism = 0.3 liter.
The water produced = 200 ml = 0.2 liter.
The water consumption = 2 L + 0.3 L - 0.2 L
Total water consumption done by the body = 2.1 liter.
Thus, the answer is 2.1 liter.
Answer:
Negative feedback.
Explanation:
Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.
The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.
Thus, the correct answer is option (c).

Answer:
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
