Answer:
populations
Explanation:
A) genotypes
Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.
Recall that genotype is the type of alleles one has.
B) populations
Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.
C) individuals
Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.
D) phenotypes
Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.
Recall that phenotype is the physical appearance one has.
Extra:
Phenotype vs. Genotype:
If A is dominant for brown hair and a is recessive for albino hair:
Genotype Aa has a phenotype of brown hair.
Genotype AA has the phenotype of brown hair.
Genotype aa has the phenotype of albino hair.
You can see how genotype and phenotype are like.
Natural selection causes changes in populations. The correct option is B.
What is natural selection?Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.
Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.
A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.
Therefore, the correct option is B.

Two sound waves are moving through a medium at the same speed. If wave x has a greater frequency than wave y, then wave x
Correct Question:
Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X
A. has a lower amplitude.
B. has a shorter wavelength.
C. has a longer wavelength.
D. has a greater amplitude.
Answer:
C. has a longer wavelength.
The basic equation of frequency and speed are
velocity = frequency x wavelength
When both waves' velocities are the same then
v1 = v2
f-1 x wavelenght-1 = f-2 x wavelenght-2
Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

Your alien friend from planet Xenon is visiting and wants to learn how to breed pea plants. You show your friend a recent batch of pea plants with purple flowers that you grew by crossing plants that had purple flowers with plants that had white flowers. Your Alien friend is confused as to why all your plants have purple flowers. How would u explain in the simplest way possible what happened? Hint: think about parents passing on alleles and dominant vs recessive. ANSWER ASAP FOR BRAINLEIST
Answer:
You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.

What does pyruvate with O2 go to?
Answer:
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.

A canyon is a small, deep valley with cliff-like sides. The Spanish word caon, which meaning “tube” or “pipe,” is where the term “canyon” originates. Thus, option A is correct.
What Canyons type of land features represented?A deep valley that has been carved into the surface of the earth over a long period of time by erosion from a flowing river is referred to as a canyon.
It is also referred to as a gorge and typically features rocky cliffs and very steep walls. One of the most well-known instances is the Grand Canyon, which the Colorado River carved out.
Canyon: A deep valley with steep walls and a V-shape created by a river slicing through hard rock. These valleys are common in the upper reaches of rivers, where the stream's fast, strong current rapidly digs the valley. Gorges are smaller valleys with a similar aspect.
Therefore, Although “gorge” is frequently used interchangeably with “canyon,” a gorge is nearly invariably narrower and steeper.

List and describe the characteristic and position on the periodic table of halogens.
Answer:
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge.

How are decreasing amounts of sea ice particularly harmful to mother polar bears and their cubs?
Answer:
Every winter, Arctic sea ice grows around the pole, its frozen tendrils threading along northern coasts. Right now sea ice has just passed its peak coverage for the year, and will begin to shrink with the coming of spring. It’s a crucial time for polar bears, whose food supply is inextricably linked to sea ice.
And in recent decades, sea ice has been shrinking faster than ever. According to the National Snow and Ice Data Center, 2019 has the seventh-lowest sea ice cover in the Arctic since they began collecting satellite data 40 years ago.
This year “doesn't break any records, but it's the trend that matters,” says University of Alberta polar bear scientist Andrew Derocher. “The downward trend in Arctic sea ice across all months is the concern,” he says, and “now we wait to see what spring conditions bring.” (Read more about global warming’s link to polar bears.)
A cold spring allows ice to linger, giving polar bears easier access to one of their favorite foods: seals. A warm spring cuts short the availability of their food super-highway....

4.habitat
Answer:
4.habitat
Explanation:
Habitat is the place or environment in which organisms normally lives and grows. Habitat may be small for small size organisms and large for large size organisms. In these habitat, the organisms lives because of the suitable environmental conditions that allows growth and survival of organisms in that environment. If the habitat is no longer suitable for the growth of organisms the organisms migrate from that area to another suitable area.
