“How is it possible that siblings with the same parents can have such different traits, such as skin tone?”

Answers

Answer 1
Hi there!

Answer: Each parent actually has two different sets of genes. Each parent only gives half of the genes to there child and the other half gets passed down randomly. So every child is born unique in there own way.

Outline the process of the Carbon Cycle.

Answers

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

In flies, red eye color (Xa) is a sex-linked recessive trait. Black eyes (XA) are the normal colored eyes for flies. What are the chances
that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10

Answers

Answer:

The correct answer is -

a. a red-eye male as their next offspring? = 25%

b. a black eye female as their next offspring? = 25%

Explanation:

The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.

So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:

        XA          Y

Xa     XaXA    XaY

XA   XAXA     XAY

On the basis of red eye male would be XaY = 1/4 = 25%

and the black eye female would be XAXA  = 1/4 = 25%

In at least 200 words explain how DNA replicates

Answers

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

~i hope this helps :)

Answer:

QUESTION:

ANSWER:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains

Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer

After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs.

The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

Overhunting of lion and cheetah populations has led to a decline in the food source population.

Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Answers

Answer:

The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

Explanation:

The decrease in zebra population also decreases the population of the predator lion and cheetah because both predators depends on zebra for their survival. Both predators used zebra as a source of food for their growth and survival so if there is high availability of zebra so the population of Lions and cheetah also increases while on the other hand, if there is decrease in zebra population, the population of lion and cheetah also decreases because of less available food for them.

Answer:

B) The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

During a hot July day, Brian and his friends play football outside. After a while, they are covered in sweat. Brian comments that sweat is just your body’s way of cooling itself. Which systems are involved in your body attempting to maintain homeostasis during high temperatures?

a. Your nervous system sends signals to your muscular system.
b. Your circulatory system gives blood to your respiratory system.
c. Your muscular system attempts to cool your skin through radiation.
d. Your excretory system attempts to cool your skin through evaporation.

Answers

Answer: B is correct I had this question too!

Similarly, the cardiovascular, integumentary (pores and skin and related structures), respiratory, and muscular structures paintings collectively assist the frame preserves a strong inner temperature. If frame temperature rises, blood vessels withinside the pores and skin dilate, permitting extra blood to waft close to the pores and skin's surface.

The temperature in the frame varies; in a frame in homeostasis (regular fitness state), the 'core' temperature is maintained inside quite a number 36-37.5.

What is Homeostasis?

Homeostasis via way of means of contracting to show chemical electricity into thermal electricity if the frame is cold, it additionally facilitates to preserve homeostasis via way of means of contracting extra or much less frequently so oxygen can get to all cells from the heart.

Thus it is clear that systems are involved in your body attempting to maintain homeostasis during high temperatures your muscular system attempts to cool your skin through radiation.

Answers

The answer is D. The insects are the same species.

The insects are the same species best describes this insect population.

What is reproductive isolation?

The fact that the two insect groups were able to reproduce and produce offspring that could also breed indicates that they are not experiencing reproductive isolation. Reproductive isolation occurs when two populations of organisms can no longer interbreed due to genetic or behavioral differences.

Since the two insect groups can interbreed and produce viable offspring, it suggests that they are not different enough genetically to be considered different species.
