The letters X and Y represent missing events. Which option correctly replaces the letters X and Y?

in X, the homologous chromosomes separate, which increases genetic diversity because of Y.

OX: anaphase
Y: independent assortment

OX: anaphase 11
Y nondisjunction

Ox prophase 1
Y nondisjunction

OX: prophase 11
Y crossing over


Answers

Answer 1

Answer:

X: anaphase

Y: independent assortment

Explanation:

Homologous chromosomes seperate during meosis 1 while chromosomes seperate at meosis 2.  

Answer 2

Chromosomes are structures present in the nucleus of plant and animal cells. It transfers the genetic information from parent to offspring. Humans have 23 pairs of chromosomes. In which 22 pairs are autosomes while the 23rd pair is the sex chromosome.

The correct answer is:

Option A. OX: anaphase and Y: independent assortment

The explanation for this is:

In anaphase 1 of meiosis 1, the homologous chromosome separates.

In an independent assortment, the chromosomes move randomly towards the pole of the cells.

Independent assortment of the chromosomes raises the genetic diversity.

In meiosis, recombination happens due to which each gamete carries a unique set of DNA.

Therefore, in anaphase, the homologous chromosomes separate, which increases genetic diversity because of independent assortment.

Answer:

Osmosis

Explanation:

Osmosis is the diffusion of water or gas molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.

Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell.

The difference in the concentration of a substance between two areas is called the concentration gradient.

Propose an explanation as to
why beta cells would have a
greater concentration of rough
endoplasmic reticulum and
ribosomes than some other cell
types.

Answers

Answer:

The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.

Explanation:

Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.

The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body.

The photos shown below illustrate a case of synpolydactyly, a genetic abnormality characterized by two phenotypes: partially or completely duplicated fingers or toes, and webbing between fingers or toes. The same mutations that give rise to the human phenotype also give rise to a similar phenotype in mice. In which family of genes do you think these mutations occur?

Answers

Answer:

The correct answer is - Hox gene.

Explanation:

Synpolydactyly is a joint presentation of syndactyly is the condition of the partially or completely duplicated fingers or toes and weblike development in between toes and fingers.

This takes place due to the Gene of HOX family that has mutated to rise this condition in the individual. The gene that is responsible for this genetic condition is the mutation in the D13 gene.

Answers

Answer:A

Explanation:

Organisms are classify on the basis of kingdoms Bacteria, Protista, Fungi, Plantae, Animalia, Phylum. Therefore, option (A) is correct.

How do we classify organisms?

Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.

It is divided into phyla or divisions, which are further subdivided into classes. Further divisions include order, family, genus and species, in that order. Thus, species is the basic unit of classification.

Organisms are usually grouped together based on their unique characteristics. The classification of an organism often provides useful information about its evolutionary history and which other organisms are related to it.

Explanation:

so early adulthood think so

The stage of human development that might be most concerned with cognitive function is advanced adulthood. The correct option is D.

What are cognitive functions?

Cognitive functions are the psychological functions that are the mental processes that are done to express feelings and actions. They are eight types of cognitive functions.

In advanced adulthood, humans use most of the cognitive functions of the body.

What exactly is the significance of the cross-over in meiosis?

Crossing over is important in meiosis because it occurs when homologous chromosomes exchange genetic material, resulting in the formation of new combinations of genetic information and increasing genetic diversity in the population. As a result, evolution occurs, and unique offspring are produced.

Hence, the diagram that explains the crossing over in the following diagram is option C, as here the crossing over takes place and the chromosomes exchange their genetic materials and can later produce the gametes.

if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart​

Answers

Answer:

If a blue-eyed offspring forms from black-eyed parents, the blue-eyed trait must be recessive.

Explanation:

The blue-eyed trait is the recessive one because otherwise it could not come from parents with black eyes. A recessive trait is only expressed when both alleles for that trait are the same, and can only come from parents with the same trait, or heterozygotes.

In this case, both parents must be heterozygous, i.e. carriers of the recessive allele. If black eyes is B and blue eyes is b, then the genotype of the parents would be:

♂ Bb♀ Bb

In a Punnett square can be seen the crossing:

Bb X Bb

Alleles    B     b

B           BB    Bb

b           Bb    bb

Where the offspring could be:

Bb black eyes 50%.BB black eyes 25%bb blue eyes 25%

Therefore, if blue eyes is the recessive trait, as if it were the dominant trait it could not be the product of black-eyed parents.

The study of a living being is called biology.

The correct answer is recessive genes or mutation.

The character in the living organism is due to the gene present in the body. The genes are present in a pair. The single gene is known as an allele. The two alleles are as follows:-

DominantRecessive

In this question, the parents have a black color eye but the offspring has blue color eyes. This is due to recessive gene inheritance because this gene is dormant in their parent and shows its character in this generation.

The chances of this case are 1/4 out of total.

The mutation is also the reason for the blue eyes because the abnormal change beside the population is called a mutation.

Hence, the correct answer is Recessive and mutation.
