Answer:
requires an intermediate found in urea biosynthesis
Explanation:
Both pyrimidine and urea are carbon and nitrogen containing compounds. Carbamoyl phosphate provides both carbon and nitrogen in biosynthesis pathways of both pyrimidine and urea. Hence, it is an intermediate in both the pathways.
In urea biosynthesis carbamoyl phosphate provides its carbamoyl group to ornithine. In pyrimidine synthesis it donates the carbamoyl group to aspartate. Carbamoyl phosphate synthetase synthesizes carbamoyl phosphate by joining ammonium ions to carbon dioxide and adenosine triphosphate.
Answer:
The importance to goblet cells and other glandular epithelia are to secrete mucus in order to protect the mucous membranes where they are found.
Answer: physiological
When we are under constant stress, our body will start expressing it with physiological responses. When the body realizes the presence of the stressor agent, sends signals to the hypothalamus, and it activates the sympathetic and hormonal
responses to eliminate the stress.
The digestive tract is a part of the body very commonly affected by stress.
"Rainwater can replace or replenish freshwater sources" and "precipitation, such as rainwater, is a source of freshwater on Earth" statements describe freshwater sources
<u>Explanation:</u>
Rainwater a source of pure distilled water, evaporated by the sun. When it falls it comes in contact of air and land. when ground soaks the water it becomes mineral water. And it is safe for drinking.
All the freshwater sources are result of precipitation from the earth surface,in various form i.e rain,mist,snow. Freshwater falling as rain have materials dissolved from atmosphere in it,sea and the land over which the clouds has travelled.
