When stomata are open, carbon dioxide enters the plant through stomata. Carbon dioxide is necessary for the process of photosynthesis in which it is converted together with water into oxygen and glucose. For most plants, it is necessary that stomata are opened during the day when there is a lot of Sunlight also necessary for the process of photosynthesis.
However, some plants from the arid locations have <span>stomata closed during the day, so they reduce water loss that way. In the night when is colder, stomata open and carbon dioxide enters through stomata. </span>
Answer:
Option (e).
Explanation:
Karl Woese was an biophysicist and microbiologist. He was known as the originator of rRNA sequences in 1967.
Karl determines the 16rRNA sequence by the technique pioneered by Woese. He breaks the prokaryotes into two groups and discovered the third domain of life.
Thus, the correct answer is option (e).
Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
