A mother and father both have brown eyes, but their child has blue eyes. Which statement most likely explains this
Answer:
Blue eyes is a recessive trait
Explanation:
Recessive traits show in 25% of the offspring, but they skip the first generation. This means that the 25% only shows up in the second generation unless two recessive traits are put together. A likely combination is that both of the parents had Bb, which you can put into a punnet square to visualize.

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

w, use what you have learned about heredity to complete the chart below. The allele pairs in the left column represent eye color in fruit flies. Ris the
ominant color (red), and r is the recessive color (white). Study the chart and fill in the missing phenotypes.
Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.

Kindly refer to the attachment.Thank U,NExt
DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
DNA contains genetic information that is passed from adult organisms to their offspring during reproduction.Each offspring forms by the combination of the parent's gene or DNAThe actual sequence of DNA on each of the chromosomes is unique due in part to recombination.recombination causes genetic variation and made everyone unique.This is incorporated in the nucleotide sequences in DNA molecules.Thus, DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA

Why does a fever become dangerous to body functions if it continues to rise?
A. Dehydration will occur
B. Osmosis may be affected due to lack of water
C. A fever breaking is more dangerous than the fever itself
D. Proteins become denatured and are unable to complete their jobs
b osmosis may be affected due to lack of water
Fever has been defined as the rise in the temperature of the body. The rise in fever is a dangerous process as lack of water causes dehydration in the body. Thus, option A is correct.
What is dehydration?Dehydration is the loss of water and body fluid than the intake of the fluid amount. The high-temperature condition of the body causes the loss of water from the body that gets evaporated from the skin cells.
When a person is suffering from fever the body fluid and electrolytes are lost by vomiting, tears, sweat, diarrhea, and urine. Dehydration can be detected by thirst, dry mouth, dizziness, etc.
Too much heat in the body during fevers results in the loss of water from the body that is more because the fluid intake gets reduced and the body becomes deficient in electrolytes and fluids.
It is a serious problem that should be dealt with so that the cells and tissues of the body can restore the water balance that is crucial for various activities and functions.
Therefore, option A. increase in the temperature in fever causes dehydration.

In a normal cellular protein, where would you expect to find a hydrophobic amino acid like valine?
A.In the interior of the folded protein, away from water.
B.On the exterior surface of the protein, interacting with water.
C.In the transmembrane portion interacting with lipid fatty acid chains.
D.In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
E. Anywhere in the protein, with equal probability.
Answer:
D. In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
In a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).
Aminoacids can contain hydrophilic side chains that interact with water molecules or hydrophobic side chains that cannot make hydrogen bonds and therefore do not interact with water.
In membrane protein, hydrophilic amino acids are arranged so they can interact with water on the surface of the cell membrane,
Moreover, hydrophobic amino acids of membrane proteins are arranged away from water so they can interact with fatty acid chains in the transmembrane portion of transmembrane proteins or with other hydrophobic amino acids in the interior of the folded protein.
In conclusion, in a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).

Explain the role of certain plant cells in flood control
Answer:
To absorb water to lowers the intensity of flood.
Explanation:
The main role of certain plant cells in flood control is to absorb water as well as the decrease the flow of water which slower down the intensity of flood. There are some plants in which their cells absorb huge amount of water which decreases the amount of water in the flood and as a result flood water decreases so that's why vegetation is very important in order to avoid flooded condition.

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.
The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.

Answer:
Remember that males have an x and y chromosome, while women have two x chromosomes.
Explanation:
This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.
This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.
The chance of a male offspring inheriting the disease is
A) 100%
Answer:
Mother
Explanation:
This mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only had one X chromosome (XY).
