B. They start as a single cell.
Answer:
glycolysis in the cytoplasm
Explanation:
~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.
Answer:
A. to enter a cell at a specific receptor site.
Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.
Answer:
Oxygen
Explanation:
Oxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight.
