Answer:
Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.
The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.
The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
<span>The answer is A. This is because the P53 gene is involved in a cell cycle regulation and is thought to hold the cell in a particular phase until DNA defects are repaired. </span>
When air is inhaled, oxygen diffuses from the alveoli into the blood to be used for respiration by the body’s cells. Carbon dioxide is a waste product made by the body’s cells during respiration.
The correct answer is a.
Even-aged practices remove larger groups of trees than uneven-aged management practices. Uneven-aged management is termed as the forest management whereby trees of different species are maintained for many sizes and ages to allow continuation of natural regeneration.
Answer:
Option E is correct.
Explanation:
It is also known as DNA replication which is biological action where two identical replicas of a DNA from one original DNA molecule is formed, the cell usually have distinct divisional property..
