the strongest animal will win in the fight of evolution

individuals are born and as they live the develop traits that will help them survive

8.

there is little to no change in the environment

there are no different traits in the populatio n

there must be genetic variation the population

This is a bunch of words to distract you from the actual question. you should just read the last question on the answers and see what makes the most sense. bacteria live in petri dishes they can evolve quickly because they have short reproductive times and squire many mutations, which is why there are many strands of bacteria that are immune to antibiotics now. we see that an experiment where bacteria in a petri dish with out antibiotics has alot of bacteria and a petri dish with antibiotics still has a few bacteria

why are there still bacteria in the petri dish with aibiotics?

a)

Natural selection, the gene that made bacteria immune to antibiotics helped them survive and became the common gene in the population

b)

natural selection, bacteria chose changed their DNA to be able to survive in the antibiotics

c)

bacteria that had the resistant gene were more attractive to other bacteria so they mated with them in a long sensual bacteria mating ritual

d)

gene flow from the bacteria in the other dish hoping over like spiderman

pick the true statement from below and dont read anything from above

a)

bacteria reproduce through asexual reproduction so there is not enough genetic variety to have natural selection

b)

genetic variation keeps evolution from happening

c)

genes are not heritable from one generation to the next

d)

evolution can only happen once in a species after that it cant anymore

you have to have a experimental group you are not testing a variable on to?

a)

have a snack for later

b)

have a dependent variable to include in your data

c)

to have a control group to know if what you are changing in the testing group is what is causing any differences

d)

its a backup in case you mess up on your testing group

12.

sloths used to be almost 10 feet tall and move quicker than they do now, why do you think sloths have changed so much

a)

migration

b)

inbreeding

c)

natural selection

d)

commercialism

13.

giant water bugs carry thousands of eggs on their backs, this is an example of what natural selection behavior

a)

overproduction

b)

variation

c)

heredity

d)

comparative anatomy

14.

bower birds give blue gifts as a mating ritual, what condition of natural selection is this behavior

a)

overproduction

b)

heredity

c)

variation

d)

reproductive advantage

15.

how are natural selection and genetic drift similar?

a)

both change allele frequency

b)

both take place in small groups only

c)

both require no mutations

d)

both are based on random chance

16.

elephant males leave their herd when they become sexually mature. what is the genetic outcome of these males leaving their herd to join others

a)

Gene flow

b)

genetic variation decreases in original herd

c)

allele frequency is constant

d)

DNA mutation increases in both herds

17.

the mainland lady bugs are a even mix of red and white, a small portion of lady bugs move to an island (seen in the picture) explain why the island population is more likely to loose the white alleles

a)

the white lady bugs would reproduce more and increase the chance of mutation

b)

it is likely the mainland environment will change favoring the white ones they will move back

c)

because the island has such a small population and have few white bugs so the chances of NOT passing on the white alleles is high

d)

in a small population they are more likely to grow where they change colors

18.

identify which one is NOT Genetic Drift (when a natural disaster or something wipes out a large part of the population or when a small portion of a population of split and secluded from the rest)

a)

moths that are dark blend in well with smog colored trees, less easy to spot in turn making dark moths common over generations

b)

lady bugs on the main land are red and yellow but when a few of them flew to a near by island only red ones arrived, the new island population only has red bugs

c)

florida had blue and green iguanas then a deep frost killed a majority of the population including all the blue ones, only green were left in the population

increases

b)

decreases

c)

keeps constant

20.

Mutations help organisms adapt to its environment because

a)

they cause harmful diseases

b)

they increase genetic variety

c)

they don't harm they individual in somatic cells

Here is a some more text to distract you from the actual question if you just read the question at the bottom and find the correct answer you can answer this more quickly.

Louis Pasteur created an experiment to test how living organisms are generated. previously it was believed spontaneous generations, or the creation of living things spontaneously forming from non living compounds was the correct understanding of creation of life. Pasteur experiment to test this looked like this: (see picture)

his results showed that when the non living substances were not exposed to the environment no new living things were generated, when the organic compounds were exposed to the environment living organisms appeared.

what did Pasteur conclude based on his results?

a)

life comes from water

b)

living organisms are NOT spontaneously generated

c)

inanimate objects when broken enough can create life

d)

when enough heat is applied to something it can create heat

23.

its theorized that the origin of life on earth started from bio molecules and energy combining. What must have occurred first for this to happen?

cellular respiration

b)

RNA created

c)

creation of monomers

d)

phospholipid bilayer

its is believed that DNA was the first genetic material not RNA, True or False

a)

True

b)

False
