What is the genotype for a h0m0zygous dominant plant? PP

What is the phenotype? Purple plants

What is the genotype for a h0m0zygous recessive plant? pp

What is the phenotype? White plants

What is the genotype for a heterozygous plant? Pp

What is the phenotype? Purple plants.

What is the genotype for a h0m0zygous dominant for freckles? FF

What is the phenotype? Freckles

What is the genotype for a h0m0zygous recessive for freckles? ff

What is the phenotype? No freckles

What is the genotype for a heterozygous individual for freckles? Ff

What is the phenotype? Freckles.

Each individual has two alleles for a given gene.

For example, the allele dimples are dominant. How would you represent this allele? With capital letters, for example, DD.

The allele for no dimple is recessive. How would you represent this allele? With lowercase letters, for example, dd.

The allele for brown eyes is dominant. How would you represent this allele? With capital letters, for example, BB.

The allele for blue eyes is recessive. How would you represent this allele? With lowercase letters, for example, bb.

PP: h0m0zygous dominant; Yy: heterozygous; Ss: heterozygous; bb:h0m0zygous recessive; FF: h0m0zygous dominant

Explanation:

Every being, such as plants, animals, or humans, have two different copies of a gene. These are alleles. These copies can be dominant or recessive.

Dominant genes are the ones that we will see. They "hide" the recessive gene. Recessive genes are the ones that we will only express if the two alleles are recessive since there is no dominant gene that hides the other.

Genotype is the genes that an individual or animal has. We can not see it. For example, a person can have a dominant trait for blue eyes and a recessive trait for brown eyes (Bb)s. In other words, it is the genetic information that a person carries. The phenotype is what we can see of a trait. Following the previous example, the dominant trait is blue eyes, and the recessive is brown, so the gene that will express itself is blue eyes, and we will able to see it.

The pair of alleles can be h0m0zygous and heterozygous. H0m0zygous is when the two traits are the same, for example, BB or bb. Heterozygous is when the traits are different, like, Bb.

Pea plants have two flower varieties where purple is dominant over white. The dominant trait, we represent it with a capital letter, in this case, P, because it is the first letter in purple. The recessive trait we represent it with a lowercase letter, in this case, p.

The genotype for a h0m0zygous dominant plant would be PP. We have to remember that the genotype is the information that the plant carries. If this information is h0m0zygous, it means the two alleles are the same, and if they are both dominant, we write capital letters. The phenotype is what we can see of the information; the gene that it is expressed, in this case, would be the color purple.

A h0m0zygous recessive plant has two alleles with the same information, and as they are recessive, we write two lowercase letters (pp). The genotype would be white plants since there is no dominant allele that covers the recessive one.

In a heterozygous plant, the traits are different. We have the dominant trait purple (P) and the recessive trait white (p). The dominant is the one that will express itself and the one that we will be able to see, see in a purple plant.

The following questions are similar to the first one. We know that freckles are a dominant trait, so we use a capital letter to represent it (F) and a lowercase letter to portrait the recessive trait, which is no freckles (f).

A h0m0zygous dominant means that the two alleles are the same and that one does not hide the other so, the genotype would be FF, and the phenotype would be a person with freckles.

If the person is h0m0zygous recessive, it means that it has the same traits, but one allele does not hide the other. The genotype would be ff, and the phenotype would be no freckles.

In the last case, the person is heterozygous, which means that it has one dominant and one recessive allele. The dominant allele will express itself; the genotype would be Ff, and the phenotype freckles.

In the following questions, we know that we represent dominant alleles with capital letters and recessive ones with lowercase letters, if it is a dominant allele for brown eyes, we write BB, taking the first letter of the dominant trait, in this case, brown. If it is a recessive trait, we write lowercase letters, in this case, bb for blue eyes.

In the last set of questions, we have to observe the letters to find the genotype.

PP, FF: the two letters are the same, which means that the allele is h0m0zygous. Also, they are both in capital letters, so they are dominant traits. Yy, Ss: the two letters are different, one is in capital letters, and the other is not. The allele is heterozygous. bb: the two letters are the same, so they carry the same information. They are h0m0zygous. Both of them are in lowercase, so they are recessive alleles.

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.

How are decreasing amounts of sea ice particularly harmful to mother polar bears and their cubs?

Answers

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....

polar bear live on the ice caps and snow so the sea ice melting is basically the same as deforestation, they’re losing their homes and since this is also affecting the fish in the ocean they’re losing their source of food and etc. hope this helps :)

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

Answers

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.

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

Answers

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.
