During which phase of meiosis does crossing over chromosomes occur

Answers

Answer 1
Answer:

Answer:

Pachytene of prophase I of meiosis I

Explanation:

Crossing over is the process of exchange of genetic material between non-sister chromatids of homologous chromosomes. It occurs during the pachytene stage of prophase I of meiosis I. During pachytene, the paired homologous chromosomes exchange genetic material between themselves and add new gene combinations to the daughter cells.

Answer 2
Answer: phase where crossing over chromosomes occur is prophase 1

The kinetic theory assumes that collisions of gas particles are perfectly elastic. What does this statement mean?

Answers

For example: if a car collides head first into each other, they would just kinda stay in that same position that they collided in because they are not elastic. But since gas particles are elastic, they would just bounce right off of each other and walls as if they didn't hit anything.

How do the products and reactants of a chemical change compare?The mass of the products is greater than the mass of the reactants because energy is taken in by the reaction.

The mass of the products equals the mass of the reactants because the same matter is present.

The mass of the products equals the mass of the reactants because there is no energy involved in the reaction.

The mass of the products is less than the mass of the reactants because energy is given off by the reaction.

Answers

The correct answer for this question is "The mass of the products equals the mass of the reactants because the same matter is present."

All chemical reactions follow the Law of Conservation of Mass which states that mass cannot be created nor destroyed. This means that mass is constant before and after a process. If ever it seems like the mass is not the same, it is possible that the missing mass was converted to something else.
