What are The answer choices?
Answer: the three objects are not always in exactly the same plane
Explanation: the diagram shows two dimensions. There is also variation in the third dimension. The Moon’s orbit is tilted relative to the sun earth plane
Answer:
D. The methyl group of acetyl CoA becomes radio-labeled
Explanation:
During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.
Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.
Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.
Answer:
The correct answer is -
1. stomata - openings that are most frequently found on the underside of a leaf.
2. Palaside layer - the layer in the leaf that is the primary spot of photosynthesis.
3. spongy layer - the layer within the leaf that has many holes and spaces for gases to exchange.
4. cuticle - the waxy protective coating on leaves.
5. epidermis - the outer layer of cells on leaves that has a waxy coating.
Explanation:
The structure of leaves has various layers and structures in it for specific functions.
Epidermis - it is the outermost protective layer of the leaf that has a waxy coating known as the cuticle.
Cuticle - it is a waxy coating that provides protection to the plant leaves and prevents moisture to move out of the cells.
Palisade layer - it is the closely packed photosynthetic pigments chlorophyll layer known as the primary spot for photosynthesis.
Spongy layer - it is the layer that has loosely packed photosynthetic cells and allows the gaseous exchange as their many small holes and spaces.
Stomata - Stomata is the holes or openings that are most frequently found on the underside of a leaf that allows for gaseous exchange.
