An allele that causes a helminth to produce eggs more quickly C. An allele that creates a non-functional cytoskeleton D. An allele that prevents algae from capturing blue light in photosynthesis

Explain how archae are more closely related to Eukarya than to bacteria even though Archae are related. Explain fully   a. both are bacteria b. both have cells c. both have nucelus d. both are prokaryotes

Which of the following statements is an evolutionary advantage of sex and sexual reproduction?   A. Sex and recombination results in decreased genetic variation in a population and maintains advantageous traits. B. Sex and recombination can bring beneficial alleles together when producing offspring. C. Sex and recombination results in the inheritance of all the genetic information available from both parents. D. Reproduction is less risky when gametes from two individuals must fuse.

Why are humans so genetically similar within our species?  A. Humans are not very genetically similar to one another.   B. Because humans evolved in one location (Africa) and we have existed as a species for very long time.  C. Because humans evolved in multiple locations around the world at different times.  D. Because humans evolved in one location (Africa) and we haven't existed as a species for very long.

What is an example of evolutionary mismatch in modern day humans?    A. Evolutionary mismatch is not a real concept.   B. Fatty and sugary foods were disadvantageous for early humans to eat, and they are overly abundant in modern times and contribute to obesity in modern humans.    C. Fruits and vegetables were disadvantageous for early humans to eat, but they are healthy for modern humans.    D. Fatty and sugary foods were advantageous for early humans to eat, but they are overly abundant in modern times and contribute to obesity.

Long bearded macaques are a (hypothetical) species of monkey who grow long white hair on their faces. A team of scientists studying a population of long bearded macaques notices that males with longer hair get more opportunities to mate and father more offspring. They hypothesize that long hair is adaptive in male monkeys. How should they test their hypothesis? a. Look for evidence of hair in the ancestors of macaques. b. Determine whether macaque hair length is heritable. c. Test if other traits in male macaques are also adaptive d. Test if male macaques who have had their faces shaved are still able to mate.* O e. Measure hair length of female macaques.

What genes did H. sapiens inherit from Neanderthals and Denisovans? (Note: you’ll need to watch the entire video to answer this question.)   A. STAT2   B. All of these are correct   C. EPAS1   D. HYAL2
