Answer: D. Jacob and Monod
Explanation:
An operon is a region of DNA that consists of a single gene regulated by more than one promoter. An operon is a region of RNA that consists of the coding regions of more than one gene. RNA polymerase is the enzyme that binds to promoters and transcribes the coding regions of genes into RNA.
Jacques Monod was the first to demonstrate the preference for certain substrates over others through his studies of E. coli’s growth when cultured in the presence of two different substrates simultaneously.
Answer: Although humans cannot prevent all cancers, a healthy diet and weight followed by adequate exercise, sleep, and stress reduction all play a part in cancer reduction.
Cancer occurs when cells multiply uncontrollably and are not "cleaned up" by the body. We are dependent on our bodies recognizing and destroying old cells and foreign substances like toxins. When our body's fail to do this, either through stress, poor diet or being sedentary, cancer could result.

Answer:
Fixation of oxygen occur instead of carbondioxide.
Explanation:
If the stomata remain closed due to water loss, the concentration of carbondioxide decreases and oxygen increases in the leaf because of the fixation of oxygen instead of carbondioxide by rubisco. The plant takes carbondioxide from the atmosphere when the stomata is open so when the stomata is closed there is no other way for getting carbondioxide into the leave so the oxygen is now being fixed by our rubisco enzyme to that five-carbon compound instead of carbon dioxide.
Answer:
This is the specific heat capacity
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise the temperature of 1 g of water by 1 degree.it is due to the aggregation of hydrogen bonding holding water molecules together.
Therefore,large quantity of heat energy is needed to be supplied to raise the temperature of water.
This is an advantage for earth temperature because a significant rise in the earth temperature,would not affect the earth because the ocean would have absorbed the heat.Therefore regulating the earth temperature within the narrow limits
However,during summer little heat is released by the ocean and this cools the earth,this is because the specific heat capacity of the ocean is higher than that of the land,thus as the ocean warms up slowly its warms the earth.
