mutation
speciation
genetic drift
gene flow
non-random mating
Answers
Evolution is a term that is used for how living things have evolved from another form different from the current form.
Of the given options, speciation is not a mechanism of evolution.
Take for instance, the human.
Human was believed to have evolved from Australopithecus to human (after several evolution stages)
There are several mechanisms that contribute to evolution.
However, speciation is not a mechanism of evolution, but instead it is a process of evolution, where new species are formed

Without genetic variation, natural selection would not be possible. Explain why.
Answers
hello
Answer:
Explanation:
Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously existed in the population. Natural selection can't select anything if there is no difference between individuals. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.
Genetic variation is the alteration of the genetic composition of an organism. Without genetic variation, natural selection is impossible as it selects species with divergent and favorable genes.
What are genetic variation and natural selection?Genetic variation is the difference in the genetic composition or the genes of the organism of the population due to mutation and environmental conditions.
Natural selection is a process that selects the genetically different and fit organism that can survive and reproduce in altered conditions.
Therefore, natural selection occurs in a population with genetic variability.

Imagine your cell phone rings. Describe how the sound gets transmitted from your phone to your ear, and then, from your ear to your brain. In your response, be sure to mention the type of wave that a sound wave is, the medium the sound is transmitted through before it gets to your ear, and what happens in your ear once the sound reaches it.
Answers
it is a mechanical wave type
The sound gets transmitted from your phone to your ear - air - eardrum- bones- nerve ending-electrical impulse - cranial nerve - the brain.
SoundSound is a compression wave that requires a medium upon which to travel. When the phone rings the sound waves of the ring travels through the air and reach the ear.
The air that vibrated due to sound waves enters the ear and vibrates the eardrum sympathetically, which acts on the bones malleus, incus, and stapes in the ear.
The vibrations of bones act on the hairs in the cochlea (inner ear), which acts on the aural nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

Where does water exit a plant (be specific)?
Answers
1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

The earths magnetic field extends far and wide but it is very weak in terms of the field strength. The field lines go out of earth near the south pole, enter earth in the north pole, and are not aligned with the geographic poles describes earth’s magnetic field lines. The correct option is B.
The earth's magnetic field is also defined as the geomagnetic field. The earth's magnetic field extends millions of kilometers into the outer space and looks like a bar magnet. The earth's south magnetic pole is actually near the north pole and the magnetic north pole is Antarctica.
The field lines go out of the earth near Antarctica, enter earth in northern canada, and are not aligned with the geographic poles.

Answers
Answer:
Every genotypic combination with DD or Dd is classified as Rh Positive (red).Explanation:
It may be because extra blood rushes to the skin's surface to fight off irritants and encourage healing. Your skin can also become red from exertion, such as after a heart-pounding exercise session.This is just an explanation of why there skin might turn red. Hope this helps!Answer: 50-60% chance of being a darker skin tone, in this case Purple (P).
And red skin would be: 40-50%
Explained:
The Genotype is the genes of an organism. A capital letter represents the dominant form of a gene ( P is a cap so it is dominant) , and a lowercase letter is the abbreviation for the recessive form of the gene (less dominant).
So darker skins have dominant traits. So
50-60% chance of being a darker skin tone, in this case Purple (P).
And red skin would be: 40-50%

Melissa lives in a town called Greendale. She discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. Melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. Her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. Melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area.
Based on this information, which three statements are plausible consequences of fracking in Greendale?
Fracking contributed to methane finding its way into the residential water supply.
Fracking is always safe to use in the proximity of Greendale's water supply.
Pressure from fracking forced methane to mix with Greendale's groundwater.
Fracking in Greendale produces more freshwater than it consumes.
If fracking can contaminate city water, it might also poison nearby rivers.

Millions of years ago, a small population of birds lived on the Hawaiian Islands. Over time, this population evolved into more than 54 separate species, each with different colors, beak shapes, and food sources. Which of the following best explains why the original population of birds evolved into so many different species?
A Many of the birds were killed each time a volcano erupted on the Hawaiian Islands.
B The Hawaiian Islands had few predator species to decrease the lifespan of the birds.
C The bird population moved into and adapted to many different environments on the Hawaiian Islands.
D The climate of the Hawaiian Islands rarely changed, which helped the bird population to increase in size.
Answers
Answer:
C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.
Why:
When a species adapts itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.
(Hope this was a good explanation.)
Which BEST describes the relationship between adaptations and environmental factors?
A)Environmental factors can determine which mutations are classified as adaptations.
B)Environmental factors determine which adaptations an organism will decide to develop.
C)Mutations determine which environmental factors will negatively affect an organism’s survival.
D)Mutations determine which adaptations a species will adopt over a period of time.
