A. The sister chromatids of each chromosome separate into different daughter
cells.
B. The two homologous chromosomes are not separated during meiosis I.
C. The two homologous chromosomes travel together into one new daughter cell.
D. The nonsister chromatids of each homologous pairs separate into different
daughter cells.
The two homologous chromosomes separate into two different daughter cells.

Answers

Answer:

two homologous chromosomes travel together into one new daughter cell.

Explanation:

in metaphase I the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. in anaphase I centromeres break down and homologous chromosomes separate. in telophase I chromosomes move to opposite pols; during cytokinesis the cell separates into haploid cells.

if you cross Bb with bb what's is the genotype ratio?

Answers

Answer:

Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.

Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.

Explanation:

Answer:

I don't know about the ration but it's going to be 25% chance for them to have an offspring with blue eyes as there is a presence of a dominant allele

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?

Answers

I believe the answer is the NUCLEUS

The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.

What is nucleus?

The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.

DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.

The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.

The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.

Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.

Thus, nucleus is only present is eukaryotic cells.

Explain why selective breeding of plants takes a long time (

Answers

Hello! Selective breeding means choosing the plants or animals that have the most pronounced desirable characteristics and breeding them. It takes generations to make the desirable characteristics develop more and more, until finally they are at the desired level. Meaning the reason why it takes so long is because you need to breed multiple generations. Hope this helps!

25% red, 50% pink, and 25% white

Explanation:

construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.

RR is red and occurs once so that is a 25% chance (1/4)

RW is pink and it occurs twice so that is 50% (2/4)

WW is white which occurs once and it is another 25% (1/4)

25%
A red flowered Snapdragon(RR) is crossed to white flowered Snapdragon(rr). The F1 individuals are Pink flowered(Rr). When F1 individuals are self crossed, in the F2 generation, 1 plant with red flowers(RR-25%), 2 plants with pink flowers(Rr-50%), 1 plant is with white flowers(rr-25%) are formed. The phenotypic ratio is 1:2:1 and genotypic ration is 1:2:1.
So, the correct option is ‘25%’.

describe the role of insulin in regulating blood sugar levels

Answers

Answer:

Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Organelle 1 is called as the nucleus that stores DNA, which would determine blood type. So, the correct option is A.

What is Nucleus?

The membrane-enclosed organelle in a cell that houses the chromosomes is known as the nucleus. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such proteins and nucleic acids) inside and outside the nucleus.

The cytoplasm and nucleus's contents are separated by the membrane. The chromosomes of the cell are also included within it. The chromosomes, which contain DNA, supply the genetic data necessary for the synthesis of various cell components as well as for the replication of life.

It regulates the cell's growth and reproduction and holds the genetic information. The genetic makeup of a cell is contained in the nucleus, which has been explained in detail as a membrane-bound structure.

Therefore, the correct option is A.

Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?
A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.

Answers

Answer: A- Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS

Answers

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.
