Answer:
mutation. random mating between organisms. random fertilization. crossing over (or recombination) between chromatids of homologous chromosomes during meiosis.
Explanation:
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
D) It is synthesized in the 5' to 3' direction
Riety of mushrooms in a Mushroom Pot at different temperatures. The Trumpet Royale Mushroom Kit produces a good mushroom to work with.
Once the pinheads (young mushrooms that look like a fat white pencil tip) form, you could measure the length of the young mushroom every 4 or 8 hours. If you measured growth rates at 60 F, 70 F, and 80 F would find a marked difference in growth rates. If the temperature is too low, the mushroom will grow very slowly or not at all. If the temperature is too high, most likely the mushroom will die.
D. They come from other living things
Explanation:
The cell theory states that all living things come from preexisting cells.
