Explanation:
Color blindness is a recessive X-linked trait. A normal couple has a color-blind child. At least one member of the couple's families is colorblind, who is this most likely to be?a) the child's paternal grandmotherb) the child's paternal grandmother or grandfatherc) the child's maternal grandmotherd) the child's paternal grandfathere) the child's maternal grandfather
Answers
Answer:
c or e
Explanation:
The correct answer would be the child's maternal grandmother or grandfather.
For X-linked traits, only females can be carriers while males are either affected or totally free from the trait. This is because females have two X (XX) chromosomes while males have only one (XY).
Since the couple is normal, it means the father is free from color blindness. The only available option now is the mother and since she is phenotypically normal, it means that she is a carrier of the disease. She must have inherited the allele from either of her parents, but not from both. If she had inherited an affected X chromosome from each of her parents, she would have been phenotypically affected for color blindness.
Hence, the child's color-blind allele can only be traced back to either of the child's maternal grandmother or grandfather.
The correct option is c or e.
The member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.
An X-linked recessive inherited genetic trait is transmitted from parent to child through mutations in genes localized on the X chromosome.In males, X-linked recessive traits are always expressed because males contain only one X chromosome.In consequence, in this case, the mother should be a normal carrier of the disease/condition, thereby her dominant X-linked allele can mask the expression of the recessive (daltonic) allele, which is passed to the child from the maternal grandfather.In conclusion, the member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?
Answers
Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.

Answers
Answer:
The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.
Explanation:
Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.
There are different enzymes, produced in the digestive system, for this purpose:
Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

what solution describes a saturated solution?
Answers
Answer:
This is not my answer, I found it on the internet.
No more solutes can be dissolved in a saturated solution at a given temperature and pressure.
Explanation:
A saturated solution is a solution that consists of maximum amount and concentration of the solute that is dissolved in the solvent.
The extra amount of solute cannot be dissolved in a saturated solution.
The saturated solution is composed of solute and solvent and solvent cannot dissolve more solute at some extent.
The carbonated beverage is an ideal example of saturated solution.
A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.
What is Saturated solution?Solvent and solute make up the saturated solution, and to a certain extent, solvent cannot dissolve more solute. A saturated solution is best exemplified by fizzy beverages.
A solute's solubility is the greatest amount of that solute that can dissolve in a solvent at a given temperature and pressure. The moles of solute per volume (mol/L) or the mass of solute per mass of solvent (g/g) are other common ways to express solubility.
There is typically a limit to how much solute can dissolve in a given amount of solvent, even for extremely soluble compounds. In general, temperature and pressure—for gases—as well as the energy components we have already covered affect a substance's solubility.
Therefore, A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.

Which are the two most important factors determining the movement of ions across the cell membrane?
Answers
Answer:
The two most important factors determining the movement of ions across the cell membrane are: the permeability of the molecule in the membrane, and the existence of an energy source.
Explanation:
Ions are charged molecules that, no matter their size, cannot pass through the membrane by simple diffusion because of the nature of the lipid bilayer of the membrane.
Ions can move across the cell membrane in two different ways: passive transport and active transport. The disparity between these two relies on the usage of ATP (energy) - passive transport doesn't need ATP while active transport does. This is where the availability of a source of energy is important, because if there isn't, then active transport is impossible.
On the other hand, ions can move through the cell membrane without the use of energy by diffusing through the membrane with the help of specific membrane proteins that form channels for ions to pass through - and this is where permeability matters: if the cell membrane is permeable to a specific ion, it means that it has opened channels for that ion to use; and this ion will move from one fluid to the other (intracellular or extracellular) following its concentration gradient (for example, sodium is poorly concentrated in the inside of the cell, while is highly concentrated on the outside - this means that sodium will go through the membrane to get inside the cell and even the concentrations between the two fluids, but only if the membrane is permeable to sodium!).

C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.
D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.
Answers
Answer:
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
Explanation:
Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.

b. tRNAs released from the ribosome are degraded B) termination and eukaryotes utilizes three different release factors.
c. Polycistronic MRNA usually has a single ribosome binding site.
e. once a single mRNA strand is translated once it is degraded
Answers
Answer:
The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.
Explanation:
Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.
To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a polysome and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.
The true statement regarding the machinery of translation is ; ( A ) A single mRNA can be translated simultaneously by several ribosomes
Translation is the process of producing protein with the use of RNA ( i.e. the process of protein synthesis from an mRNA template ) during translation the code found in the template is converted into an amino acid sequence.
Ribosomes are composed of rRNA which directs the process of translation with the proteins and key molecules such as tRNA.
Hence we can conclude that the true statement regarding the machinery of translation is A single mRNA can be translated simultaneously by several ribosomes.

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable
Answers
Answer:
temperature
Explanation:
The independent variable would be the colored water at different temperatures.
The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.
In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.
