Question

A species of birds lives in a particular niche. As their population increases, many of these birds migrate to new niches with different food sources.

In niches where hard seeds and nuts are the main food sources, the birds with stronger beaks succeed and grow in population. In niches where small insects and larvae are the main food sources, the birds with longer, narrow beaks succeed and grow in population.

This is an example of how

genetic engineering leads to more diversity.
natural selection leads to more diversity.
genetic engineering leads to less diversity.
natural selection leads to less diversity.

Answer 1

I think it's D

Answer 2

Thanks!

Answer 3

Answer 4

Peppered moths use the adaptation of camouflage as protection from predators. They may have a variety of colors or shades, but before the Industrial Revolution, they were typically white with black speckles. The Industrial Revolution in the 1880s introduced large-scale pollution into the environment. The pollution resulted in widespread, dark-colored staining of buildings and trees.

Which of the following was the most likely effect of the Industrial Revolution on peppered moths in cities?

The peppered moths adapted an improved sense of sight and smell.

The population of light-colored moths decreased and the population of dark-colored moths increased.

The peppered moths developed a tolerance to smog and chemical waste.

Over time, the white, speckled moths were outnumbered by plain white moths.

Answer 5

No. I think its A

Lol well, @shreehari499 give @sarah786 a gold medal :3

Answer 12

Sure...!! :)

Answer 13

Fossils can reveal which of the following about a species or organism?

the growth stages of the organism's species
the microscopic features of the organism
the appearance of the organism and its structures
how the organism interacted with other organisms

Answer 14

Its C

Answer 15

(Its a select each answer question, Meaning: More than one)

Answer 16

Some organisms have favorable traits that are well-suited to the environment at hand. Organisms with this advantage are more likely to thrive, reproduce, and pass their traits to future generations than organisms without favorable traits.

This process is known as

artificial selection.
natural selection.
selective breeding.
genetic engineering.

Answer 17

This is Natural Selection for sure....1000% sure :)

Answer 18

Examine the evolutionary diagram below. What does the diagram imply about the peafowl and field mouse?




They share a remote common ancestor.
They did not evolve from older forms of life.
They share a recent common ancestor.
They are unrelated.

Answer 19

Its A) They share a remote common ancestor.

Answer 20

Some species that appear to be very different from other species can actually have similar anatomy. For example, scientists believe that whales evolved from land mammals. One reason for this is the presence of several functionless hind-limb bones still found internally in a number of whale species.

What is the term for a reduced, often functionless anatomical structure that serves as evidence of an organism's evolutionary past?

homologous structure
absorbed structure
trace structure
vestigial structure

Answer 21

vestigial structure

Answer 22

Which of the following is true about natural selection?

Natural selection usually causes a species to change gradually.

Natural selection usually causes a species to change suddenly.

Natural selection does not cause a species to change.

Natural selection is the only cause of changes in a species.

Answer 23

Natural selection usually causes a species to change gradually.

Answer 24

Fossils are most commonly found in which type of rock?

igneous
sedimentary
paleolithic
metamorphic

Answer 25

Oh wait

Answer 26

xD I know this one already xD

Answer 27

Its B

Answer 28

What does the fossil record reveal about new species of organisms?

They evolved over time from older species.
They developed without any relation to other organisms.
They changed into warm-blooded organisms.
They became larger over time.
