They go through mitosis to create identical copies of themselves.

They go through meiosis to create haploid (1/2) cells of themselves.

They go through several bacterial partners before they meet their "A" partner.

Genes are not a part of stem cells.

Genes are either turned on or off depending on what cell the body needs to make.

Genes are inherited so when stem cell specializes, it asks a parent for permission.

Fish: both whales and fish live in the ocean meaning they are both fish.

Mammal: evidence from anatomy and DNA show whales have a more recent common ancestor will mammals.

Mammal: whales have to be mammals because I really don't like fish.

Primates and rodents have a more recent common ancestor.

Primates and birds have a more recent common ancestor.

Primates are equally related to birds and rodents.

Yes. This characteristic is on the cladogram.

No. This characteristic occurred later in time.

Maybe. It's not clear from the cladogram.

Directional and disruptive both favor several phenotypes.

Directional favors just one phenotype while disruptive favors two extremes.

Directional selection favors the average phenotype while disruptive doesn't favor any phenotype.

Maybe. Antibiotics can be dangerous because they can create super bacteria.

Yes. The COVID-19 virus is alive and antibiotics kill living things.

No. Antibiotics are used to fight bacterial infections not viral infections.

I don't know. I'll highlight it on my study guide to review later.

There is variation in the population, heritability in the trait, and a reproductive advantage to those who have that trait.

There are directional, stabilizing, and disruptive selection patterns in the bacterial populations.

There are fossil, DNA, and embryology evidence supporting the evolution of bacteria.

Someone with dark skin will survive in high UV and thus reproduce.

Different skin colors provide an advantage in different environments due to variation in UV radiation.
