if in the cell have ten chromosomes and want to divides by meosis how many daughter cell will be formed?

Answers

Answer:

Explanation:

If a cell with ten chromosomes undergoes meiosis, it will result in the formation of four daughter cells. Meiosis consists of two rounds of division, known as Meiosis I and Meiosis II.

During Meiosis I, the cell undergoes a process called homologous chromosome pairing and crossing over. This results in the separation of homologous pairs of chromosomes, reducing the chromosome number from 10 to 5.

Then, during Meiosis II, each of the daughter cells formed in Meiosis I will undergo a second round of division. In this round, the sister chromatids within each cell separate, resulting in the formation of four haploid daughter cells, each containing five chromosomes.

Therefore, when a cell with ten chromosomes undergoes meiosis, it will produce four daughter cells.

Answer:

If a cell with ten chromosomes undergoes meiosis, it will form four daughter cells.

Explanation:

During meiosis, the cell goes through two rounds of division, resulting in the formation of four haploid daughter cells. In the first round of division, called meiosis I, the cell divides into two daughter cells, each with half the number of chromosomes as the original cell. In this case, each daughter cell would have five chromosomes.

In the second round of division, called meiosis II, each of the two daughter cells from meiosis I divides again, resulting in a total of four haploid daughter cells, each with five chromosomes. So, a cell with ten chromosomes undergoing meiosis would produce four daughter cells, each with five chromosomes.

Answers

Animals perform many behaviors which are caused by stimuli, or a signal that causes an organism to react in some way. An animal's response to this stimulus may include external actions or internal changes, such as a faster heartbeat, or both.

Thus, animals perform some instinctual behaviors without being taught, but most learned behaviors result from another animal's experience. A behavior that is a combination of instinct and learning is imprinting, which can be seen in a newly hatched bird that recognizes and follows the first moving object they see.

Learning that a particular stimulus or response can lead to a good or bad outcome is called conditioning. One form is trial-and-error learning in which animals learn to perform a behavior more skillfully through practice. Sometimes past experiences can be used to solve problems, and when this occurs, animals are using insight learning.

Which of the following would provide evidence that the mutated form of the CFTR protein is harmful to human

Answers

The correct option is D, as epidemiological studies showing that individuals with the CFTR mutation have a higher risk of developing respiratory infections and other complications provide support for the idea that the mutated form of the CFTR protein is harmful to humans.

What happened to cause the CFTR gene to become mutated?

F508del is the most prevalent CFTR mutation, seen in around 70% of patients with CF. The deletion of three base pairs in the CFTR gene results in the lack of an amino acid termed phenylalanine, abbreviated F, in the CFTR protein.

Recessive diseases include cystic fibrosis.

A mutated variant of the CFTR protein is dangerous. Individuals who inherit the mutant variant of the gene are more likely to experience major health issues.

Option D is accurate because it implies that epidemiological research supporting the hypothesis that the mutant version of the CFTR protein is detrimental to humans would demonstrate that people with the CFTR mutation have a higher chance of having respiratory infections and other issues. This is consistent with the widely held belief that the CFTR mutation has detrimental effects on health and causes problems with cystic fibrosis.

Black fur is dominant and white hair is recessive in rabbits. A white female has 2 white bunnies and 2 black bunnies. What was the genotype and phenotype of the father? You are not making baby bunnies so you need reasoning skills not a Punnett square.

Answers

The father would be dominant recessive. The mother is white so therefore her genotype would be recessive, bb . And the offspring are 50%, 50%. So therefore there has to be a Dominant gene present to form black offspring. But he can not be completely dominant or all the offspring would be black. So the fathers genotype would be Bb B=black b=white and his phenotype would be black.

A homozygous variety of opium poppy with lacerate leaves was crossed with another homozygous variety with normal leaves. All the F1 had lacerate leaves (jagged-edged leaves). Two F1 plants were crossed to produce the F2. Of the F2, 249 had lacerate leaves and 16 had normal leaves.
How are lacerate leaves determined in the opium poppy?
Give genotypes for all the plants in the P, F1, and F2 generations. Some generations will have more than one genotype.

Answers

Lacerate leave specified in the opium poppy is two genes, with a dominant allele at either or both loci.

Genotypes for all the plants in the P, F1, and F2 generations is F1 (lacerate = AaBb) and F2 (Lacerate leaves = A_B_ ⇔ aaB_ ⇔ A_bb) (Normal = aabb)

Crossing homozygous lacerate leaves (AABB) with homozygous normal leaves (aabb). Then it will produce the first offspring (F1) heterozygous torn leaves (AaBb).

Parental crosses (F1): AABB >< aabb

Gametes: AB >< bb

F1: AaBb (lacerate)

If F1 is crossed with each other, it will produce F2 offspring as follows:

Parental cross (F2): AaBb >< AaBb

Gametes: AB, aB, Ab, ab >< AB, aB, Ab, ab

F2: see picture

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water

Answers

The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.

Why do polar molecules repelled by the phospholipid bilayer?

Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.

What component of the phospholipid bilayer is water-repellent?

While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

What was the population's antibiotic resistance level like after antibiotic treatment (1 sentence)?​

Answers

Answer: A diverse population of bacteria that is treated repeatedly with the same antibiotic and not all of them die will eventually lead to the emergence of antibiotic-resistant bacteria that will thrive and become dominant. The population's antibiotic resistance level before being exposed to the antibiotic was low or non-existent. The "good" bacteria will die while the antibiotic-resistant bacteria will survive and reproduce. After antibiotic treatment, the population's antibiotic resistance level will be higher than before.

Explanation:

1. Researchers studied a population of 34 peregrine falcons for one year to analyze the effect of pesticides on population growth. In the first three months, 57 eggs were laid. Owing to thin shells suspected to have resulted from pesticide damage, 28 eggs broke. Of the remainder, 20 hatched successfully (Figure 6). However, nine baby falcons died from severe birth defects. During the next 6 months, 11 birds died as a result of direct pesticide exposure, and 8 were captured and taken to a conservation area. During the last three months, four birds migrated into the area. Determine the population growth of peregrine falcons in this study.

Answers

The population growth of peregrine falcons in this study is 55.

The population growth of peregrine falcons in this study is calculated as follows:

Initial population: 34 falcons

Eggs laid: 57

Eggs broken: 28

Eggs hatched: 57 - 28 = 29

Baby falcons died from birth defects: 9

Total number of surviving baby falcons: 29 - 9 = 20

Birds that died from direct pesticide exposure: 11

Birds captured and taken to conservation area: 8

Birds that migrated into the area: 4

Total population growth: (Initial population) + (Surviving baby falcons) - (Birds that died) + (Birds captured) + (Birds migrated)

= 34 + 20 - 11 + 8 + 4

= 55

Therefore, the population growth of peregrine falcons in this study is 55.

The population growth is calculated by taking into account the changes in the falcon population over the course of the study.

The initial population is given as 34 falcons. From the eggs laid, the number of broken eggs is subtracted to determine the number of eggs that hatched successfully.

The number of baby falcons that died from birth defects is subtracted from the surviving baby falcons.

The birds that died from direct pesticide exposure are subtracted, and the birds captured and migrated into the area are added. The result is the population growth of peregrine falcons, which in this case is 55.
