Another? What are the answers xD
A)Since the population is isolated so that no other alleles are introduced, the population is in Hardy-Weinberg equilibrium. B)The brown deer mate more often, so mating is not random, and the population is not in Hardy-Weinberg equilibrium. C)The population must be small so that some alleles will be prominent, and since the population is large, it is not in Hardy-Weinberg equilibrium. D)Natural selection must not affect the population, and since fur color gives no survival advantage, the population is in Hardy-Weinberg equilibrium.
LOL im not sure if its A or B
I would choose A, as a lack of gene flow is part of the requirements for H-W Equilibrium
Your doing virtual school I'm guessing?
okay :D haha thanks i probably have a few more just trying to double check my work before i turn it in :D
and yes i am lol
It's alright I can help out xP
Florida virtual school? Or another
florida virtual lol
LOL I'm doing that to xD
I'm actually doing Biology atm
nice! what grade are you in?
I'm supposed to be in 12th lol let's just say that xD
nice lol same here xD
Alright we let's see those other questions I think I know all of them because I took that test at my last high school. Well I've seen those 2 before lol
The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows: Species A: CAGGCCATTATG Species B: CCAGCCTATAGG This DNA sequence has a known mutation rate, which the scientists used to calculate that the species diverged from a common ancestor 80 million years ago. Using this information, how much more time do you predict will pass before these species differ by a total of eight base pairs?
do you know the equation im suppose to use ?
Sequences currently differ by 5 bases. Over 80 million years = one mutation per 16 million years. Three more mutations = 48 million years
48 is your answer I'm pretty sure :)
thank you omg your the best !
Based on fossilized evidence, there are scientific claims made about the evolution of certain species. If a scientist studying the fossils of a specific species had a hypothesis other than what was currently accepted, what steps should be taken to have the alternative hypothesis considered? A)ince the original hypothesis is untestable given the circumstances, another one is more likely to be correct. B)If an alternative hypothesis sounds plausible it could be used in place of the original hypothesis. C)The scientist should publish the alternative hypothesis in a popular magazine to gain public support. D)It is useful to test alternative hypotheses and know that they are incorrect.
I beieve the answer is c
It is useful to test alternative hypotheses and know that they are incorrect.
Wait I just noticed what you did there xD
I would publish it to
The insulin used to treat people with diabetes is commonly produced by inserting the DNA sequence for human insulin into a bacterium. The insulin the bacterium produces using that sequence is then harvested. In fact, DNA sequences from virtually any living organism could be inserted into a bacterium and the bacterium would be able to use the sequences to make the same proteins that the original organism did. In what way does this provide evidence for evolution? A)Since bacteria are able to use DNA from other organisms, they must have evolved from them as a common descendant. B)Bacteria must be less evolved than higher organisms since they can still make proteins from the DNA of other organisms. C)Since the genetic code is the same across species, these species must have inherited it from a common ancestor. D) Since the bacterium was changed by adding a foreign DNA sequence, the bacterium was able to evolve.
Okay its either c or d
I believe that one is D
Most of these questions are confusing until you re read them a couple times and then your like, "Really" lol
Mass extinctions have occurred repeatedly during the course of Earth's history. One of these events occurred at the end of the Cretaceous Period, during which the dinosaurs became extinct. Mammals flourished after the dinosaurs were gone. This led to a variety of generically diverse species. Why did the mammals suddenly start diverging into different species after the dinosaurs were gone? A)Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce. B)Once the dinosaurs were gone, the mammals started having larger numbers of offspring in each litter to fill the empty niches. C)The mammals chose to move into the vacant niches the dinosaurs had occupied and change their body shapes to suit these new environments. D)Mammals began mutating rapidly once the dinosaurs died out and were able to create new species based on the mutations.
yeah i agree lol i have to get going soon tho i have practice and a game today xD haha
twank you !
Your lucky lol I'm on house arrest
It sucks lol
lmfao so are most of my friends xD but they all live right by me so i just go annoy them after school !
A researcher is studying a population of 100 beetles that eat flower pollen. They are confined in a large aquarium in his lab and have fresh flowers to graze on every day. Eighty-four of the beetles have smooth shells, a dominant trait, while the other 16 show the ridged shell recessive trait. The beetles mate and produce offspring, increasing the proportion of ridged shells in the population to 49%. How has the frequency of the ridged allele changed between the two generations, and how might the conditions for Hardy-Weinberg equilibrium have been violated for this to happen? A)The ridged allele increased by 30 percent between generations, which was likely caused by having a small, nonrandomly mating population. B)The ridged allele increased by 30 percent between generations, which was likely caused by mutations in several of the smooth-shelled beetles. C)The ridged allele increased by 33 percent between generations, which was likely caused by having a large population in a small enclosure. D)The ridged allele increased by 33 percent between generations, which was likely caused by isolating this population from other beetle populations.
My friends come by every now and again lol but yeah
my freiends mostly come over summer and just stay at my place for like a month or 2 haha xD
I'm thinking this is D but I'm not sure
And lol that sounds fun xD I'm just waiting 4 months till I hit 18 then going to move in a with a friend
same here 0.o lmfao
An anthropologist compares the remains of H. neaderthalensis to earlier hominid species, like H. habilis, and to the contemporary and later species H. sapiens. He believes that H. neanderthalensis were the first hominids to bury their dead. Which of the following would be a valid reason to question the reliability of this idea?
A)Finding a fossil of H. habilis beneath fossils of H. neanderthalensis B)Finding fossils of H. neanderthalensis skeletons in isolation C)Finding burial sites of modern H. sapiens in the same region as H. neanderthalensis fossils D)Finding burial sites of H. habilis on different continents
