<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer. Obviously we can't say whether chickens will have teeth with certainty, the chickens with teeth are clearly still chickens, and a baby croc isn't hatching out of a chicken egg any time soon.

Explain how diabetes can affect two other human body systems.
Leviafan [203]
Considering people who suffer from diabetes can have issues and need help with circumventing the difficulties this disease can pose for them, it's very possible that other people (who are part of the support structure/inner social group of the person who's suffering from it) would need to help him or her with his diabetes issues.

This answer explains how other people might be affected by someone having diabetes in their particular social group. I hope this was what you were interested in, your question seemed to ask this.

Two species of tree frogs that live sympatrically in the northeastern United States differ in ploidy: Hyla chrysoscelis is diplo
Artist 52 [7]

Answer:

The correct answer is - polyploidy.

Explanation:

Speciation can be two types allopatric and sympatric speciation. Sympatric speciation is the process of speciation is developing the new species that diverged from the common ancestral species while the ancestral and developed species both can share the same place or geological area. The main cause of such speciation is due to the change in their genetic level more than environmental conditions.

In this case, the frog's species show differences in their ploidy level as well as their mating call but polyploidy is the most likely the difference that evolved first rather than females call for mating.

Thus, the correct answer is - polyploidy.
