Answer:

More darker skins are more resistant to disease than lighter skins.

Explanation:

  • The skin color pigmentation is based on the genetic makeup that is biological factors and physiological factors such as solar insolation, heat humidity, and temperature. The human's skin color ranges from dark brown to lighter hues.
  • The people who live near the tropics are much darker occurs due to the pigmentation of skin as compared to those that live near the arctic. The presence of melanocytes in the skin cells helps in deterring fitness and evolutionary traits.

Answer:

Anatomy supports the theory of evolution because some species share similar physical features that was present in a common ancestor.

An example of shared anatomy is sharks and dolphins. types of analogous structures, such as dolphins and sharks, do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments

Molecular biology because DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

in recent research is has been shown that the myoglobin and hemoglobin sequences for dozens of mammals, birds, reptiles, amphibians, fish, worms, and molluscs were related.

Structural similarities is when different animals share the same structural similarities. For example the skeletons of turtles, horses, humans, birds, and bats are very similar, despite their t different ways of life and the diversity of their environments.

Xelga [282]

Answer:

I agree and disagree with his statement.

Explanation:

We all know that the blood type AB is the universal recipient, so we know that this bloodtype can recieve any kind of blood. AB-type blood doesn't fight off anything because it has all of the antibodies needed. We also know that type O is the universal donor, meaning that this blood can be donated to anyone. This bloodtype doesn't have antibodies, so nothing will go wrong. However, for the other bloodtypes, yes, things have to be matched carefully. Type B blood can't be given type A blood, and so on. Another thing you have to think about is the Rh factor, which is the +/- after blood types. Rh+ bloodtypes can recieve both Rh+ and Rh- bloodtypes, but Rh- bloodtypes can only recieve Rh- bloodtypes. There are also graphic tables that will help answer this question if you're a visual learner!

I hope this helps, sorry it was a bit late!
