Answer:
92.
Explanation:
92 chromatids are visible for humans at prophase stage because the replication of 46 chromosomes occur. When the replication of chromosomes occur, each chromosome is converted into two chromatids so when 46 chromosomes replication occur then it changed into 92 chromatids. So we can say that there is 92 chromatids in humans in the prophase stage of mitosis.
Electric and mechanical energy
Answer:
The least likely to be a source of genetic variation among living organisms is asexual reproduction. Asexual reproduction is a kind of reproduction that does not include fertilization process of two gametes: female and male but only includes parts of plants or cells. In this case, variation is minimized
Explanation:
Answer: Don’t listen to the other person, B is incorrect. A is the correct answer.
Explanation: The law of conservation of energy states that energy cannot be created nor destroyed. B says that the mechanical energy disappears, but this is wrong. It changes into another energy, but the energy doesn’t disappear.
