Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

Explanation:
Why do continents rise above the ocean floor?
Answer:
This increase is linked to the continental crusts rising above the oceans. ... As Earth's land plates began to shift and move, less dense rock may have been forced upward, shaping the continents we see today on Earth's crust.
Explanation:
Answer:
the second one
Explanation:
As a result, the rock that forms from that melt is less dense than the original rock.

Which of these items would undergo cellular respiration to obtain energy from its food? Choose the three that apply.
an oak tree
a rock
a deer
a grass hopper
Answer:
An oak tree, a deer and a grasshopper
Explanation:
Just took the test
All the organisms such as an oak tree, a deer, and a grasshopper would undergo cellular respiration to obtain energy from its food. Thus, the correct options are A, C, and D.
What is Cellular respiration?Cellular respiration is the process through which the cell produces energy. Cellular respiration occurs in the mitochondria of the cell. This is also called as aerobic respiration.
Cellular respiration involves the production of energy in the form of ATP (Adenosine triphosphate) from the food (carbohydrate) which they consume. Cellular respiration occurs in the cells of every living organism on this planet.
Therefore, the correct options are A, C, and D.

How has the study of genetics shaped our understanding of heredity? Include Gregor Mendel’s studies to support your answer.
Answer:
resessive and dominant genes.
Explanation:
we foumd out that was a thing. like red hair is recessive. black hair is dominant. that kind of thing.
Answer:
Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn't until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.
