The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer.
HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys
HbS: Val-His-Leu-Thr-Pro-Val-Glu-Lys
Yes The two peptides will separate from each other in an electric field when the pH is 7.0
The two peptides wil drift/separate from each other when the pH is 7.0 because of the reaction of trypsin enzyme and also the difference in charge between HbA and Hbs
Considering charge of each peptide
Since The isoelectric point of normal Hba is 6.9 and Hbs possess two fewer negative charges per hemoglobin molecules
The Hbs is more hydrophobicity than HbA due to the substitution of glutamic acids of HbS by valine residue.
Considering Electrophoresis
At a lower pH level Hbs shows a slower moving band than Hba
while a higher pH level the HbS peptide is less negatively charged while the carboxyl group of HbA is more negatively charged and Hba moves faster as well as an acidic pH.
Hence we can conclude that the two peptides will separate from each other in an electric field when the pH is 7.0

The pedigree on the right shows the inheritance pattern for an X-linked recessive disorder.
The mother of the individuals circled in pink is not shown on the pedigree. Based on the phenotypes of these individuals and their father, what are the possible genotypes of their mother? Check all of the boxes that apply.
- XAXA
- XaXa
- XAXa
The mother's genotype can be either [tex]X^AX^A[/tex] or [tex]X^AX^a[/tex].
For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.
The circled male child is free from the disorder ([tex]X^AY[/tex]) while the females are carriers ([tex]X^AX^a[/tex]).
The male inherited the healthy allele, [tex]X^A[/tex], from the mother.
The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.
This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.
Thus, the possible genotype of the mother are [tex]X^AX^A[/tex] and [tex]X^AX^a[/tex].

Is fermentation as efficient as aerobic cellular respiration? Multiple choice question, yes or no?
Answer:
NOEXPLANATION :
Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration. They quickly die if deprived of oxygen.

How would an error during mitosis cause a different effect on the body than an
error during meiosis
A mistake in the process of mitosis leads to the development of the daughter cells having chromosomes without segregation.
What is mitosis?A cell undergoes cell division by replicating its chromosomes, segregating chromosomes, and creating two identical nuclei during the mitotic phase. The cell organelles are divided equally between two daughter cells with the same set of genomes after mitosis.
Prophase, prometaphase, metaphase, anaphase, and telophase are the main four stages. Meiosis creates cells that are genetically distinct from the parent and have half as much DNA as mitosis, which divides a single "parent" cell into two genetically identical cells.
Therefore, mitosis is a process used in the somatic cells whereas miosis is in fertilization.

vermiform appendix is a vestigial organ in human being give reason.
Answer:
The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm. Vestigial in that sense means that the vermiform appendix seemingly has no functions or is useless now but they might have had functions previously which are lost someway due to evolution.
Explanation:
Vestigial organs are organs, tissues or cells in a body which are not functional anymore the way they were in their ancestral form of the trait. It is therefore authentication of evolution and hence were helpful in explaining adaptation.
Which statement is true about the particles in liquid water at 100°C and the particles in steam at 1000C? (Select ALL that apply)
the particles will have the same kinetic energy
the space between the particles is different with more space between particles in a gas
the particles will have different kinetic energy
the space between the particles is different,with less space between particles in a gas
The particulate nature of matter explains that when a substance gets heated it particles gets energised and they move away from one another in a random manner, hence the correct options are
The space between the particles is different with more space between particles in a gasThe particles will have different kinetic energyWhat happens to particles when they are heated
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?
Explanation:
The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32
To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.
The Hardy-Weinberg equation is given as:
p² + 2pq + q² = 1
Where:
p = frequency of one (dominant) allele
q = frequency of the other allele (recessive) allele
p² = expected frequency of homozygous dominant individuals
2pq = expected frequency of heterozygous individuals
q² = expected frequency of homozygous recessive individuals
To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.
