Answer:
The correct option is 'A'
The breezes are the pollinator of pine trees.
Explanation:
Pine tree belong under genus Pinus and family Pinaceae which are important for it's timber and wood pulp.
Pine trees are mostly monoecious as the male and femlae contain cones which is present on the same tree but few are sub dioecious with single sex.
As they lack flowers,so pollination is not done by bee or butterfly.But they mainly pollinate by breeze or wind.
Female cone require 1.5 to 3 years to gain maturity after pollination.
At the onset of maturity, the diameter of female cone is 3-60cm long
The answer is; D. The movement of water molecules from an area of high concentration to an area of low concentration
A is not correct because Osmosis does not create DNA.
B is incorrect because the movement of molecules through the cell membrane is called Passive Transport.
C is incorrect because the division process of the cell's cytoplasm is called Mitosis.
<u>Thus brings us to </u><u>D </u><u>which is the correct answer because Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.</u>
Answer:
Aerobic respiration saves a lot of energy compared to anaerobic respiration. Aerobic activities can generate up to 38 ATP per gram of glucose consumed. Anaerobic reactions only produce 2 ATP per gram of glucose.
