Choose the phase of meiosis in column 2 that best matches each event in column 1. - one haploid set of replicated chromosomes at each spindle pole - genetic recombination events take place - shortest stage - aligning of bivalents in the center of a spindle - one haploid set of unreplicated chromosomes at each spindle pole - aligning of monovalents in the center of a spindle - separation of homologous chromosomes - separation of sister chromatids A. telophase II B. anaphase I C. metaphase I D. prophase II E. anaphase II F. telophase I G. metaphase II H. prophase I

Answers

Answer:

H. prophase I → genetic recombination events take place

C. metaphase I → aligning of bivalents in the center of a spindle

B. anaphase I → separation of homologous chromosomes

F. telophase I → one haploid set of replicated chromosomes at each spindle pole

D. prophase II → shortest stage

G. metaphase II → aligning of monovalents in the center of a spindle

E. anaphase II → separation of sister chromatids

A. telophase II → one haploid set of unreplicated chromosomes at each spindle pole

Explanation:

Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.

1. In the first phase, Meiosis I:

Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane. Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.

2. In the second phase, Meiosis II:

Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.

explain why you would recommend the nguni cattle meat to consumers in your locality?​

Answers

Answer:

Due to their natural growth.

Explanation:

I would recommend the meat of Nguni cattle to consumers in the locality because of their pure quality. These cattles have excellent resistance to internal and external parasites with natural immunity to kill borne diseases. There is no injections or vaccines are given to these cattles which enables them to grow in natural environment. So due to their natural growth, the meat have higher quality as compared to other cattle's meat.

Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?

Answers

Answer:

Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.

Explanation:

In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.

Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Belle, who was born on the same date at the same hospital. Mrs. Green, having recently seen Belle, is convinced that Belle and Georgia had been assigned to the wrong parents at the hospital. Mrs. Green thinks that Belle is her biological daughter. ABO blood analysis was performed on all individuals involved:Mr. Green: Type AMrs. Green: Type A Georgia: Type AMr. Blue: Type ABMrs. Blue: Type ABelle: Type O
Is Mrs. Green correct? Is Belle her biological daughter? Explain.

Answers

Answer:

Yes, Mrs Green is correct that Belle is her biological daughter

Explanation:

According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.

Based on the blood analysis, the following were obtained:

Mr. Green: Type A

Mrs. Green: Type A

Georgia: Type A

Mr. Blue: Type AB

Mrs. Blue: Type A

Belle: Type O

The genotype of the following blood types is as follows:

Type A - iAiA or iAi

Type B - iBiB or iBi

Type O - ii

Type AB - iAiB

From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.

However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.

The correct answer is - D. They convert energy from the sun to chemical energy.

Explanation:

In any food web, producers are the organism that can make their own food and energy by converting light energy coming from the sun into chemical energy, this process called photosynthesis.

Normally producers are green plants. These are present at the bottom of the energy pyramid as these are the highest in the number. Consumers et energy from producers by feed on them.

write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond​

Answers

(See the attached picture)

Direction: Write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond.

Answer:

The goal of the sperms’ journey to the egg is to fertilize it. To do so, the sperm cell must pass through a long and challenging path. This is one of the reasons why the total number of motile sperm cells is very important, and a key parameter for a man’s potential to reach pregnancy with his partner.

The sperms’ journey to the egg begins with millions of sperm cells that are released into the female reproductive tract during intercourse. The sperm cells gain their full ability to swim when they are ejaculated into the reproductive tract.

Upon ejaculation, the sperm cells are enclosed in a fluid called seminal plasma or semen, which is a mix of fluids from the testes, seminal vesicles, prostate, and the bulbourethral glands. The fluid contains elements which protect the sperm cells during their journey towards the egg. The semen thickens and helps the sperm cells stay inside the woman – as close as possible to the cervix, which is the “gate” to the egg.

Liquid extends from the cervix, allowing the sperm cells from the semen to swim into the cervix. Only the strongest sperm cells will make it this far. Once through the cervix, the sperm cells swim across the uterus and into the fallopian tubes.

I hope it helps!!

The sperm cell fertilizes the egg and forms a zygote, which is further divided into multiple cells and becomes a child. The division is the process of mitosis that takes place from the zygote to the child's development.

How is the zygote formed and developed?

The sperm and the ovum are produced by the process of meiosis from the male and female, respectively, and when both fertilize, the zygote is formed. The fertilized zygote is a single cell, but later that cell is further divided mitotically and forms a morula, then a blastula, and then the gastrula.

The cells of the gastrula undergo cell differentiation, different organs are developed, and the baby is finally formed. The child then continues to grow in size, and different organs grow and form the mature organ system. After a certain age, the reproductive organs start to mature and are capable of forming the gametes.

Hence, all of these events occurred from the zygote to the child's maturity.
