Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis

Answers

Answer 1

Answer:

To acquire growth and to replace worn out and defected cells.

Explanation:

The main purpose of mitosis is to acquire growth and to replace worn out and defected cells.

In prophase, the chromatin condenses which is present in the nucleus of the cell.

Prometaphase is the stage where the nuclear membrane breaks apart into numerous "membrane vesicles".

Metaphase is the phase where all the genetic material is condensing into chromosomes.

Anaphase is the stage in which chromosomes are pulled by the spindle fibers to opposite poles of the cell.

In Telophase, the cell is nearly dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.

Cytokinesis is the process which divides the cytoplasm of a parental cell into two daughter cells.

In a population of cattle, the average body fat percentage is 10.5%. You select parents with an average body weight percentage of 20.8%. The offspring they produce have an average body weight percentage of 17.6%. Based on these data, what is the narrow-sense heritability of this trait

Answers

Heritability in the narrow sense -h²- refers to the proportion of the phenotypic variability that is influenced by genetic factors. In the exposed example, the narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

-----------------------------

Before answering the question, let us first review a few concepts.

The selection differential, SD, is calculated by getting the difference between the mean value of the desired trait in the population (X₀) and the mean value of the same trait expressed by parents, (Xs). So,

                                                     SD =  Xs - X₀

Heritability in the narrow sense -h²- is the measure of the genetic component to which additive genetic variance contributes.  

It referes to the proportion of the phenotypic variability that is influenced by genetic factors.

The heritability might be used to determine how the population will respond to the selection done, R.  

                                                        h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h² with the selection differential, SD.  

                                                          R = h²SD  

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),  

                                                          R = X₁ - X₀

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:

Population average body fat ⇒ 10.5% ⇒ X₀  Selected parents average body weight ⇒ 20.8% ⇒ XsOffspring average body weight ⇒ 17.6% ⇒ X₁

We ned to get the narrow-sense heritability of this trait, h².

h² = R/SD

R  = X₁ - X₀ = 17.6% - 10.5% = 7.1%SD = Xs - X₀ = 20.8% - 10.5% = 10.3%

     

h² = R/SD =  7.1%  /   10.3% = 0.689 ≅ 0.7

The narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?

Answers

It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.

In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.

An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.

In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.

A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.

A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).

In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

I possess empathy and a subsumed theory of mind. I can project my own emotions and desires onto those of other beings. I therefore assume that all emotional beings value their own life as I do my own. Out of my empathy for others and my desire that others will empathize with me, I can value the lives of other emotional beings on their behalf. Because it is impossible to know with any certainty what of my emotional being will survive end of life, I place a very high. Perhaps the highest value on my life and by extension the lives of others. To me it seems that spiritual belief precepts which undermine the singular uniqueness of this life experience through afterlife or reincarnation mythologies those can only undermine and lessen the value i.e. the sanctity of life.

Answers

cell membrane as it is a semipermeable surface

The cell membrane allows gases and nutrients in and out of the cell.

The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.

The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:

Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.

Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.

In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

What is a similarity between phases of moon wi2 and wk 4

Answers

The similarity is that in both phases, the moon is only ¼ lit.
The moon has four phases, which happen in a fixed sequence. Each phase lasts one week and takes place as follows:

1st week - New Moon: At this moment, the part of the moon that is illuminated by the sun is not facing the earth. This prevents the moon from being seen.

2nd week - Crescent Moon: Only ¼ of the moon is being lit by the sun and facing the earth. Therefore, we can only visualize a small part of the moon.

3rd week - Full Moon: The face of the moon that is facing the earth is completely illuminated by the sun, which allows this entire face to be visualized.

4th week - Waning moon: Once again, only ¼ of the moon is lit by the sun and facing towards the earth.

The moon does not have its own light, but reflects the light received by the sun, for this reason, we cannot fully visualize the moon.
