Explanation:
The cell must be lysed (broken open) to release the nucleus. the nucleus (if present) must also be open to release the DNA. at that point the DNA must be protected from enzymes that will degrade it, causing shearing. [[ once the DNA is released, it must then be precipitated in alcohol...]
Answer:
The correct answer is option C. They absorb water vapor from the atmosphere, providing water to the plant for photosynthesis.
Explanation:
Stomata are small opening present on the lower side of leaf. Its main function is to exchange of gases that are required for the process of photosynthesis. During day time, stomata are open and carbondioxode which is a raw material used for the production of glucose is absorbed from air and oxygen is released in the atmosphere.
The correct answer is (c) the moon' gravity
The moon's gravity causes oceans to bulge. The moon's gravitational power is responsible for the rising and falling tides.The moon affects the ocean on the sides of the planet facing and facing away from it which causes oceans to bulge away from the earth. On one side ocean bulges away from the earth as planet is being pulled towards the moon and on the other side the ocean bulges towards the moon. Bulges facing towards the moon is high tides and bulges not facing towards moon is low tides.
