Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.
Answer:
Active transportation
Explanation:
Active transportation is happening because energy is need to pump against the gradient. Whenever energy is used the transportation is active.
I believe the primary structure will be preserved. The secondary level of proteins is defined by patterns of hydrogen bonds between the main chain peptide groups. Therefore distorting the Hydrogen bonds disrupts the secondary structures. The primary structure on the other hand is not affected by disruption of the hydrogen bond since these structures refers to the sequences of amino acids in the polypeptide chains that are joined by the peptide bonds.
The answer is:
False
Here is why:
What makes this statement false is "mouth." Polypeptide digestion starts in the stomach and it ends in the small intestine, in the duodenum to be more specific. Polypeptides cannot be directly absorbed by the body, so they are broken down into either individual amino acids, dipeptides or tripeptides so they can be absorbed.
The methods they are using now and days is cross fertalization. To make certain types of crops, and better/best celling crops
