Answer part D please

Each of the following three questions contains two lists. The first is a list of some characteristics of our own species, Homo sapiens, that distinguish it from LUCA. The second is a list of possible sequences (reading from left to right) in which these novelties were acquired by our ancestors during the course of human evolution. Choose the number of the correct sequence. If none is correct, choose "None of the above." Here is the first pair of lists: A. Bilateral symmetry B. Bony skeleton C. Mitochondria D. Notochord E. Multicellularity O D, E, B, A, C O C, E, A, D, B O E, C, A, D, B O A, E, C, D, B O None of the above

Melting Temperature (Tm) of a dsDNA molecule is the temperature at which a 100% of the dsDNA exists in a single stranded (denatured form). b Temperature at which the first dsDNA molecules denatures. c 50% of the dsDNA exists in a single stranded (denatured form). d Temperature at which the dsDNA solution starts boiling.

Biology You are analyzing a qPCR experiment and obtain the following results. The slope of the gDNA standard curve is -4 and the R2 = .999 for the linear fit of the line. From this slope, should you trust the quantities you get for your unknown samples? Why or why not. Show any relevant calculation(s) to support your answer

What is the difference between a primary and continuous mammalian cell line?   Question 5 options:   Primary cell lines can be maintained indefinitely unlike continuous cell lines   Primary cell lines are cancerous and continuous cell lines are not   Continuous cell lines can be maintained indefinitely whilst primary cell lines last up to 100 generations   None of these

Discuss whether the phenomenon of reproductive isolation applies to bacteria, which reproduce asexually. How would a geneticist divide bacteria into separate species?

Please answer 4

QUESTION 2) A new species of squirrel has been discovered in the Himalayas, but scientist disagree if the new species is closer to a Kashmir woolly flying squirrel (Eupetaurus cinereus) or to a Kashmir flying squirrel (Eoglaucomys fimbriatus). To resolve the issue, we sequenced a fragment of its DNA and compared it to the other two. a. Using the sequences below, construct a phylogenetic tree using Maximum Parsimony. Please identify the informative sites in the alignment, draw all the possible hypothesis and place the changes along the branch. Finally, clearly identify which is the correct tree. Flying squirrel: A GACTGAG Woolly flying squirrel: CTATT TAG New Species: CTTCTAAG Ancestor: AGTTTGAG b. Explain which squirrel species is closer to the newly discovered species. Do the Kashmir Flying squirrel and the new species form a monophyletic group?
