having two sets of chromosomes, one inherited from the mother and the other set inherited from the father.
Having two sets of chromosomes, one inherited from the mother and the other set inherited from the father occurs in organisms that reproduce by sexual reproduction.
In the field of science, sexual reproduction can be described as a process by which the male and female gamete join in order to produce a fertile offspring.
The daughter cell or the zygote formed after the fertilization process has two sets of chromosomes. One from the father and the other one from the mother. Hence, sexual reproduction is the process by which offspring are produced that have tow sets of chromosomes.

A nonsense mutation typically reduces the length of the polypeptide and thus alters its function. this is due to the fact that the of the protein is terminated prematurely is True.
It results in a truncated protein that is either non-functional or destroyed.4This form of substitution variant tells the cell to prematurely stop translating, rather than causing an alteration in the amino acid, as is the case with other types of substitution variants.In other words, this point mutation causes an early stop codon to be added to the mRNA sequence, where a stop codon is created by changing just one nucleotide. When this happens, the translation is stopped before it is finished, which causes the protein to be abnormally truncated.To know more about mutation check the below link:

the symptoms of diphtheria are due to an exotoxin that blocks proteins synthesis in host cells.
The symptoms of diphtheria are due to an exotoxin that blocks proteins synthesis in host cells. The above statement is true.
The diphtheria toxin, also referred to as an A-B toxin, is a single polypeptide chain with 535 amino acids that is made up of two subunits connected by disulfide bridges. The B subunit, the less stable of the two subunits, binds to the cell surface, allowing the A subunit, the more stable portion of the protein, to enter the host cell. The crystal structure of the diphtheria toxin homodimer has been established to 2.5 Ångstrom resolution. Three domains make up the Y-shaped molecule that is revealed by the structure. The catalytic C domain is present in fragment A, while the T and R domains are present in fragment B.
The C domain, which is the amino-terminal catalytic domain, features a unique beta+alpha fold. By transferring ADP-ribose from NAD to a diphthamide residue of eukaryotic elongation factor, the C domain inhibits protein synthesis. The T domain or TM domain, a central translocation domain, lacks the first globin helix homologue but contains two extra helices at the amino terminus and a multi-helical globin-like fold. It is believed that this domain unfolds in the membrane. The transfer of the C domain into the cytoplasm and insertion into the endosomal membrane are both facilitated by a pH-induced conformational shift in the T domain.

It is true that three-fourths (3/4) of the offspring will have purple flowers.
A monohybrid cross is one in which parents with only one distinct characteristic are crossed. Mendel proposed the law of dominance based on garden pea plant monohybrid crosses.
In the heterozygous state, a dominant allele is one that can fully express itself. In this instance, it has been established that the white flower color outweighs the purple flower color. As a result, heterozygous plants with this trait will have purple flowers.

If the density of ethanol is 0.789 g/mL, how many milliliters are produced in this reaction?
C6H12O6 --> 2 C2H5OH + 2 CO2
The volume of the ethanol is 6.7 mL
What is the density of the ethanol?We know that density is defined as the ratio of the mass to the volume of an object. We know that the density is said to be an intrinsic property and this means that we can use the density of the object to be able to obtain the kind of object that we are dealing with.
We have the information that the mass of the carbon dioxide that can be obtained from the reaction is about 10 g. We can now use this to obtain the number of moles by the use of the formula;
Number of moles = mass/ molar mass
= 10 g/44 g/mol
= 0.23 moles
From the reaction equation:
1 mole of ethanol produces 2 moles of carbon dioxide
x moles of ethanol produces 0.23 moles of carbon dioxide
x = 0.23 × 1 /2
= 0.115 moles
Mass of ethanol = 0.115 moles × 46 g/mol

Quantitative and polygenic inheritance refers to the contribution of different genes to the expression of a trait, generating phenotypic graduation according to the interaction between the alleles. Option B. Two diallelic genes are involved in the production of color.
What are quantitative and polygenic inheritance?
When the expression of a phenotypic trait depends on the additive effect of a series of genes, we talk about quantitative heritability.
Polygenic inheritance occurs when a trait results from the interaction of more than one gene.
The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits can be measured, such as longitude, weight, and eggs laid per female, among others.
These characters do not group individuals by any precise and clear categories. Instead, they group individuals into different categories that depend on how the genes intercrossed and distributed during meiosis.
The result depends on the magnitude in which each allele contributes to the final phenotype and genotype.
When they interact, they create a gradation in phenotypes, according to the contribution level.
In the exposed example we have a color gradation, so we can assume we are talking bout quantitative heritability.
Cross 1)
Parentals) dark-red strain x white strain
F1) 100% medium-red

Following the provided data, we know that dark-red and white are homozygous individuals.
From the cross between dark-red and white individuals, we got medium-red individuals, so we will assume the dark-red color is the dominant phenotype.
Medium-red is the heterozygous genotype because most individuals express this phenotype.
Two diallelic genes must be coding for this feature.

The proportion of the population who will be heterozygous carriers of the recessive allele is 0.48 according to the hardy-Weinberg equilibrium.
According to the Hardy-Weinberg principle, allele frequencies in a population are consistent and stable throughout generations. The gene pool, or the total number of genes and alleles in a population, does not change over time. We refer to this as genetic equilibrium. The sum of all allelic frequencies equals one.
For instance, specific frequencies can be given names like p, q, etc. P and Q stand for the frequency of allele A and allele an in a diploid.
In a population, p2 is the proportion of AA people. The likelihood that an allele A with a frequency of p exists on both chromosomes of a diploid individual is just the product of the probabilities of p2. This is how it is also known.
Similar to this, aa's is q2 and aa's is 2pq.
Consequently, the binomial expansion of (p+q)2 is p2+2pq+q=1, or 1.

Anaerobic respiration during exerciseAnaerobic respiration during exercise is a type of respiration that occurs when the body is working at a high level and is unable to take in enough oxygen to meet its energy needs.
During anaerobic respiration, carbohydrates such as glucose are broken down and converted into energy in the form of ATP (adenosine triphosphate) without the use of oxygen.
