Answer:
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

Hope this helps pls mark brainliest!!!
Answer:
all organism evolved on earth, and all are genetically related to one another. Species living under unusual conditions might defer more than others, though. We might also predict that the more similar the percentages of naturally occurring elements are in two species, the more closely related those two species are.
Explanation:
this is what i am assuming the answer could be :)
Answer:
Lead is toxic mostly because during biochemical reactions it tries to substitute certain metals. hence while doing this, It disrupts with the proteins that control blood pressure, the production of heme and the formation of sperm. Through reactions that propagate electrical signals in the brain, lead often consumes calcium, which reduces the capacity to think and retrieve information.
