Answer:
A-B-C-D
Explanation:
PROPHASE; 1. chromosomes become thicker
2. nuclear membrane disintegrates
3. centrosome divide to form centrioles
4. centrioles move to the opposite polls of the cell
METAPHASE; 1. chromosomes get arranged at the equator
2. centrioles produce spindle fibre that attach to the middle of the chromosomes
ANAPHASE; 1. shortest stage of mitosis
2. spindles will pull apart each chromosomes to form chromatids
TELLOPHASE; 1. each chromatid moves to opposite polls of the cell
2. nuclear membrane appears around both of them
3. the centrioles sill stop producing spindles
4. centrosomes will then form again
cytokinesis then divides by the cleavage furrow to form the two daughter cells
Answer:
Superposition
Explanation:
Sedimentary rocks are deposited one on top of another. The youngest layers are found at the top of the sequence, and the oldest layers are found at the bottom.
Answer:
Human cells can readily absorb folic acid; bacteria cells cannot.
Explanation:
Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.
The correct answer is: [B]: "decreased" .

In a graph of "coal reserves in the United States" vs. "time" ;
→ the "time" is the "independent variable" that belongs on the "x-axis" .
→ The quantity or amount of "coal reserves in the United States" is the "dependent variable" that belongs on the "y-axis" .
If the graph "slopes downward" ; this would indicate a "decrease" in the amount/quantity of "coal reserves" over "time" .
→ As the value of "x" increases — "time" increases — and; as "x" increases, the value of "y" {the amount/quantity of "coal reserves"} decreases.
→ This would be represented by a "downward sloping" graph;
→ and, among the answer choices given, could indicate that coal production:

→ "decreased" ;

→ which is: Answer choice: [B]: "decreased" .
