Scientists have observed that pythons have vestigial leg bones. they have also observed that snakes in general have more dna sequences in common with four-legged geckos than they do with legless eels. what do these two observations have in common? (2 points) they both suggest that geckos evolved from snakes. they both suggest that pythons are more primitive than other snakes. they both suggest that snakes evolved from an ancestor with legs. they both suggest that snakes evolved from geckos.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

There are only about 250,000 known fossil species. true or false

Which statement correctly compares metaphase i and metaphase ii? in metaphase ii twice as many chromosomes line up along the middle of the cell as in metaphase i. in metaphase i twice as many chromosomes line up along the middle of the cell as in metaphase ii. in metaphase ii twice as many chromosomes are pulled to opposite ends of the cell as in metaphase i. in metaphase i twice as many chromosomes are pulled to opposite ends of the cell as in metaphase ii.
