Rephrase the law of conservation of mass in your own words

Answers

Answer 1
Answer:


the mass of matter remains the same even when undergoing a chemical change because matter can neither be created or destroyed
Answer 2
Answer: The law of conservation of mass basically says that nothig can be "created" or "destroyed" but that thigs just under go transformations and change into something else. For example, take a pile of wood. If light it on fire it doesnt disappear, i have just changed it into ash and thermal energy.

All BUT one factor contributes to biological evolution. That is...A) mitosis.
B) mutation.
C) crossing over.
D) sexual reproduction.

Answers

Mitosis enhances genetic continuity rather than variation. Mitosis is responsible for the growth, repair, and maintenance in organisms. Mitosis occurs when simple organisms, like a paramecium, reproduce asexually. All organisms have the same four nitrogen bases within their DNA, but how they are expressed in individuals is a result of their rearrangement as well as changes or mutations during sexual reproduction.

A: Mitosis! Since mitosis is the literal cloning of cells, it wouldn't increase genetic diversity of the gene pool.
