Question:

Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light  green -> LG; Dark purple-> DP, Light purple -> LP)

How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?

Answer:

Possible chromosome combinations:

LG,LP + DG,DP  LG,DP + DG,LP        

The random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is different and depends on the chromosomes that form that cell.

Explanation:  

1) During meiosis, organisms can produce at least four different  gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.

The possible chromosome combinations in the two daughter cells of the exposed example are

LG,LP + DG,DP  LG,DP + DG,LP      

2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

       

Answer 2

Possible chromosome combinations:

LG,LP + DG,DP   LG,DP + DG,LP        

The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.

Anaphase I

Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.

During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.

The possible chromosome combinations within the two daughter cells of the exposed example are-

LG,LP + DG,DP   LG,DP + DG,LP    

 

Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.

Metaphase I

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.

The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.

When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.

Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.

When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.

This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.

Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

Which of the following explains why meiosis contributes to genetic variations?
A - it increases the ratio of mitosis within an organism
B - It produces offspring that are different from either parent
C - It decreases the rate of mutation occurrence
D - It forms DNA that is resistant to environmental changes

Answers

Answer:

A

Explanation:

The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.

Why does meiosis contributes to genetic variations?

Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.

Also, it rises the mitosis ratio within an organism

Hence, the option A is correct.

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?

A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.

C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.

D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.


I think it’s B, but I’m not completely sure. Help please!

Answers

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

True/ False: Substances will diffuse more rapidly through a dense substance. Explain

Answers

Answer:

I'd say true

Explanation:

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.

Answer:

False

Explanation:

As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.
