Identify the structure represented in the picture . Then, identify the parts labeled A—D.
Given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.
A= spike
B= Envelop
C= Nucleic acid
D= Capsid
What are Viruses?Small infectious agents known as viruses can multiply only in the living cells of other animals. They are composed of genetic material, which can be DNA or RNA, encased in a protein shell called a capsid. Some viruses also have a lipid-based outer coat.
Because they cannot perform metabolic functions on their own and require a host cell to reproduce, viruses are not considered living organisms. They spread infection to various living things including bacteria, plants, animals and people.
A virus replicates its genetic material and forms new viral particles when it infects a host cell using the host cell's machinery. This can lead to the death of the host cell and result in the spread of the virus to other cells of the host.
Therefore, given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.

The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or insertion mutation. Identify which sentence represents a substitution, which represents a deletion, and which represents an insertion.
Answer:
The question is incomplete, the complete question has been added as an attachment.
THE DGR AN represents deletion mutation
THE RED ANA TRA N represents insertion mutation
THE FOX WTS RED represents substitution mutation
Explanation:
Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.
An insertion mutation is the addition of one or more nucleotide bases to the sequence.
A substitution mutation is the replacement of one or more nucleotide base in a sequence.
The original sentences were:
1. THE RED ANT RAN
2. THE FOX WAS RED
3. THE DOG RAN
The three sentences that mutated/changed are:
1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.
2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.
3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
How can you determine the optimum pH of an enzyme?
You can determine the optimum pH of an enzyme by graphing its pH activity and studying the results.
Enzymes each perform differently in distinct environments. Some require lower pH to function, while others achieve maximum performance at higher pH levels.
This relationship between the productivity of the enzyme and the pH can be studied and graphed. Once done, we can expect this graph to look like a parabola, increasing steadily until maxed, then gradually decreasing back to zero at the other extreme. The vertice of this parabola will give us the optimum pH for the enzyme.

Industrial melanism refers to the dark pigmentation that evolved in some insects giving them protective coloration on vegetation darkened by soot in heavily industrialized areas prior to air pollution regulation. Assume that in one heavily polluted area near Birmingham, England in 1956, 79% of the moths of the species Biston betularia were black due to the presence of a dominant gene for melanism. Estimate the frequency of the dominant allele in this population, and the proportion of black moths that are heterozygous.
Answer:
The frequency of the dominant allele, p = 0.542The proportion of black moths that are heterozygous 2pq = 0.496Explanation:
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the same way, the sum of genotypic frequencies equals 1, this is
p² + 2pq + q² = 1
Being
p the dominant allelic frequency,q the recessive allelic frequency,p² the homozygous dominant genotypic frequencyq² the homozygous recessive genotypic frequency2pq the heterozygous genotypic frequencyIn the exposed example, 79% of the moths of the species Biston betularia were black due to the presence of a dominant gene for melanism.
If the genotypic frequency of back moths is 0.79, then, by performing the following equation we can get the not-black moths genotypic frequency:
p² + 2pq + q² = 1
where p² is the homozygous dominant genotypic frequency, q² the homozygous recessive genotypic frequency, and 2pq is the heterozygous genotypic frequency.
As 0.79 is the phenotypic frequency of black moths, then this frequency equals p²+2pq.
Clearing the equation:
p² + 2pq + q² = 1
0.79 + q² = 1
q² = 1 - 0.79
q² = 0.21
The genotypic frequency of non-black moths is 0.21. So, from here we can calculate the allelic frequency:
q² = 0.21
q= v 0.21
q = 0.458
If 0.46 is the allelic frequency of non-black moths, then by clearing the equation p + q = 1, we can get the p allelic frequency:
p + q = 1
p + 0.458 = 1
p = 1 - 0.458
p = 0.542
The genotypic frequency p² = (0.542)² = 0.294The heterozygote genotypic frequency2 x p x q = 2 x 0.542 x 0.458 = 0.496
Finally, we can check this answer by clearing the following equation:
p² + 2pq + q² = 1
0.294 + 0.496 + 0.21 = 1

Answer:
Bacteria have smaller populations, grow faster, and also share more genes compared to mammals.
Explanation:
Because bacteria reproduce quicker and are also in smaller populations, they can evolve quicker because more genes are shared which can be helpful. This is due to natural selection, which will affect bacteria more than mammals because their small populations will make natural selection more significant to be harmed by mutations and allow them to evolve.
A cell has two pairs of submetacentric chromosomes, which we will call chromosomes IA, IB, IIA, and IIB (chromosomes IA and I B are homologs, and chromosomes IIA and IIB are homologs). Allele M is located on the long arm of chromosome IA and allele m is located at the same position on chromosome IB. Allele P is located on the short arm of chromosome IA, and allele p is located at the same position on chromosome IB. Allele R is located on chromosome IIA and allele r is located at the same position on chromosome IIB.
A. Draw these chromosomes, identifying alleles M, m, P, p, R, and r as they would appear in metaphase I of meiosis. Assume there is no crossing over.
B. Taking into consideration the random separation of chromosomes in anaphase I, draw the possible types of gametes that might result from this cell’s undergoing meiosis. Assume that there is no crossing over.
Answer:
A) Allelic position in the chromosomes:
IA ----------M------------:-----------P----
IB ----------m------------:-----------p----
IIA -----------------R--------------------:---------------------
IIB -----------------r---------------------:---------------------
B) Types of gametes (assuming there is no crossing over):
MPR; MPr; mpR; mpr.
Explanation:
In submetacentric chromosomes, the centromere is located near to the middle of the chromosomes.
Since these two pairs of homologous chromosomes do not undergo crossover, the resulting gametes after meiosis may have four (4) allele combinations.

You are studying a bacterium that utilizes a sugar called athelose. This sugar can be used as an energy source when necessary.Metabolism of athelose is controlled by the ath operon. The genes of the ath operon code for the enzymes necessary to use athelose as an energy source.You have found the following:The genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high.When glucose is absent, the bacterium needs to metabolize athelose as an energy source as much as possible.The same catabolite activator protein (CAP) involved with the lac operon interacts with the ath operon.Based on this information, how is the ath operon most likely controlled?Drag the labels onto the diagram to identify the small molecules and the states of the regulatory proteins. Not all labels will be used.POSITIVE CONTROLa) Inactive Activator (not glowing, w/o yellow square)b) cAMPc) Active Activator (glowing, w/ yellow square)NEGATIVE CONTROLd) Active Repressor (glowing, w/o yellow square)e) athelosef) Inactive repressor (not glowing, w/ yellow square)
Answer:
POSITIVE CONTROL
c) Active Activator
d) Active Repressor
NEGATIVE CONTROL
f) Inactive repressor
a) Inactive Activator
b) cAMP
Explanation:
The positive controls are those groups in the experiment whose treatments are expected to confirm previously known results, thereby enabling the comparison of these results with the target group. In this case, both active activators and repressors are able to give results that can be compared with the test group
The negative controls are those experimental groups where no response is expected. In this case, both inactive activators and repressors, and cAMP (which is a secondary messenger in diverse biological processes but is not involved in this pathway), are not expected to produce any measurable response.
What explains the presence in living humans of DNA sections which are identical to DNA
found in Neanderthals who lived 40 000 years ago?
Answer:
It can be explained by hybridization among human and neanderthal ancestral populations.
Explanation:
Next-generation sequencing (NGS) technologies coupled with bioinformatics tools have enabled to confirm admixture between Neanderthals and humans. The technique to identify admixture events consists in discovering nucleotide regions from neanderthal genomes that could be inserted in human genomes, thereby the observed sequence homology must be statistically significant (e-value). This emergent research field is known as paleogenomics.
The genetics of a-thalassemia are similar to narrow sense heritability in that there is a gradation of phenotype, with each allele seeming to contribute equally to the trait. However, there are also differences from narrow sense heritability. In particular, as you can see from your answers above, it is difficult to predict offspring phenotype based only on parental phenotype. What two aspects of HBA1 and HBA2 combine to offset what would otherwise appear to be narrow sense heritability of a-thalassemia?
Answer:
In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia .
Explanation:
A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.

O c.
construct a hypothesis and record data
D.
analyze the results and make a conclusion
Answer:
Explanation:
The next step in this experiment is constructing a hypothesis and recording data. The correct option is (C).
Making observations and keeping track of data would be the experiment's next phase. The learner would observe and record the ripening of both apples at locations A and B in this stage. They would have to keep track of the maturity of the apples throughout time by routinely observing and recording the changes. This could entail examining the apples visually for color, texture, and overall maturity and recording any variations between the apples at locations A (by themselves) and B (next to a banana).
The student can analyze the results and develop conclusions regarding the impact of bananas on the maturity of other fruits by gathering information on the ripening of the apples in both locations. The information can be used to prove or disprove the initial theory and assist determine whether bananas actually influence the maturity of surrounding fruits.
Hence, the correct option is (C). Construct a hypothesis and record data.

Explanation:
Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine
The given question is incomplete, the complete question is:
Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine. If the nitrogen ingested in food is 100 g/day, but only 80% of the food is actually absorbed, while the rest goes to waste, what is the amount of nitrogen lost by excretion? Assume steady-state. Of the nitrogen liberated from muscle, 90% is excreted, while the rest is recycled, what fraction of the nitrogen entering the muscle is from the absorbed food? (In other words, what is the ratio A/(A+R)). Again, assume steady-state
Answer:
The amount of nitrogen lost in the process is 20 grams in a day and the fraction of nitrogen entering the muscle is 0.909.
Explanation:
Based on the given question, the amount of nitrogen absorbed is 80 percent of 100 grams, that is,
100*(80/100) = 80 grams in a day.
The concentration of nitrogen lost in the process is,
Nitrogen ingested-nitrogen absorbed = 100-80 = 20 grams in a day.
Let us assume that all the ingested nitrogen is liberated from the muscle. Therefore, 80 grams of nitrogen is liberated. If 90 percent of the nitrogen liberated from the muscle get excreted, then the value of excreted nitrogen will be,
90% of 80 grams = 90/100*80 = 72 grams
Now the nitrogen recycled will be,
Liberated nitrogen - excreted nitrogen = 80-72 = 8 grams
From the absorbed food, the fraction of the nitrogen entering the muscle will be,
80/(80+8) = 80/88 = 0.909.
