Will give the brainiest! Please answer it correctly and thoughtfully. Please answer the first question with AT LEAST 2-3 sentences, while the last one can just be examples 1. Meiosis is two divisions of a reproductive cell’s nucleus. It occurs in a continuous series of steps. Compare AND contrast the steps of meiosis I to meiosis II.

2. Describe mutation. Give EXAMPLES where mutations could be harmful, beneficial, or neutral.

1. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. 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.

2. Answer! A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. I hope it helps! :)

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
