A would decrease the need for reproduction, so that's not it.
C wouldn't be helpful - less food wouldn't want you to produce more organisms, it would mean more competition for less food
D wouldn't be helpful, asexual reproduction creates a limited gene pool that is less likely to be resistant to diseases
So B is the answer, because the more of the species there are, the greater chance of survival.
Origin of Prokaryotic and Eukaryotas. Fossil records indicate that Eukaryotas evolved from prokaryotic somewhere between 1.5 to 2 billion years ago<span>. Two proposed pathways describe the invasion of prokaryotic cells by two smaller prokaryotic cells.</span>
<span>c.)The product only has different physical properties than the reactants because a chemical reaction occurred.
This is because rust can behave differently than oxygen and iron. This is because a chemical reaction has happened- a chemical reaction is when a new product is formed. Rust can be change chemically and physically. </span>
Oh yeahhh thanks for the points
