Which stage of mitosis occurs the least often and why?

Answers

Explanation:

The Anaphase stage is the shortest phase of mitosis. During this phase, disjunction occurs, and migration of sister chromatids away from each other to the poles of the cell occurs, leading to the formation of daughter chromosomes. Molecular motors use ATP to shorten the spindle fibers attached to each sister chromatid

Describe at least two ways in which nitrogen is important to biological processes. (Hint: Find the biological chemicals that contain nitrogen.)

Answers

Answer:

Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things.  Without amino acids, plants cannot make the special proteins that the plant cells need to grow. Without enough nitrogen, plant growth is affected negatively.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.​

Answers

Answer:

Explanation:

This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.

When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.

---------------------------    

The first step is to understand the given information. So,

The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II)  Among the fifth generation there are two plants with wrinkled seeds

Let us assume that a diallelic gene determines the shape of seeds.

D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seeds

Now, let us analyze the pedigree. According to the information provided here, we can tell that

black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individuals

Remember that Generations are represented with roman numbers.

We will name the plants with numbers from 1 to 26.

According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.

Option 1:

Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.

Option 2:

One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.

A mutation is a random change in DNA which therefore affects a gene and/or chromosome. Most mutations have no effect on the phenotype. Some influence phenotype to some extent. Very few create a new phenotype. Mutations can be inherited and therefore passed on from one individual to another. If a mutation causes a new phenotype that makes an organisms better suited to a particular environment, it can lead to rapid change in the characteristics of the individuals in that species.
