A condensed form of DNA that occurs when the cell is dividing, option (a) is correct.

Chromosomes are condensed structures of DNA that occur when the cell is dividing. During cell division, DNA molecules undergo a process of condensation and coiling, resulting in the formation of visible chromosomes. These structures contain genetic information in the form of genes. Chromosomes ensure that genetic material is evenly distributed to daughter cells during cell division.

They consist of a central region called the centromere, which plays a role in the separation of chromosomes during cell division, and two arms known as chromatids. Each chromatid contains a copy of the DNA molecule. Chromosomes are temporary structures that revert back to an uncondensed form of DNA called chromatin during interphase, the non-dividing phase of the cell cycle, option (a) is correct.

Increased glucagon, decreased insulin, and lower blood glucose levels can promote weight loss by stimulating the breakdown of stored fat, limiting glucose storage, and encouraging the body to utilize fat and protein for energy.

Increased glucagon, decreased insulin, and lower blood glucose levels can lead to weight loss due to the following reasons:

Glucagon: This hormone stimulates the breakdown of stored fat (lipolysis) and the release of fatty acids into the bloodstream. As a result, the body uses these fatty acids as an energy source, leading to weight loss.

Insulin: Lower insulin levels indicate that there is less glucose in the bloodstream. Insulin helps to store glucose as glycogen in the liver and muscles. When insulin levels are low, the body is unable to store as much glucose, and it begins to break down stored fat for energy, leading to weight loss.

Blood Glucose Levels: Lower blood glucose levels mean that there is less available energy for the body to use. In response, the body breaks down stored fat and protein to generate the necessary energy, which contributes to weight loss.

Answer: Hijacking of host cell's metabolic action

Answer: D is the answer.

Explanation:

The approximate percentage of base T is also 32%. In DNA, the amount of guanine (G) is equal to cytosine (C), and the amount of adenine (A) is equal to thymine (T).

Polymer composed of two polynucleotide chains that coil around each other to form a double helix is known as DNA.

As the percentage of C is given as 18%, we know that the amount of G is also 18%, since they always pair up.

That leaves us with 64% of the DNA to be accounted for. Since A pairs up with T, we can assume that the percentage of A is also 32%. Therefore, the approximate percentage of base T is also 32%.

So the approximate percentage of each base is:

Adenine (A) = 32%

Thymine (T) = 32%

Cytosine (C) = 18%

Guanine (G) = 18%

Answer:

The correct option is;

D. 45%

Explanation:

From the Hardy- Weinberg law, we have;

p² + 2·p·q + q² = 1

p + q = 1

Where:

p = Dom inant allele frequency in the population

q = Recessive allele frequency in the population

p² = The percentage of individuals in the population that are hom ozygous dominant

q² = The percentage of individuals in the population that are homo zygous recessive

2×p×q = The percentage of hete rozyous individuals in the population

The number of individuals that express the recessive phenotype = 86

The number of individuals in the population = 200

The percentage of  individuals that express the recessive phenotype, q² = 86/200 = 0.43

Therefore;

q = √0.43 = 0.656

p + q = 1

p = 1 - q = 1 - 0.656= 0.344

∴ The frequency of  individuals that express the do minant phe notype, p = 0.344

The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%

The answer is 50%, or B.

Enhancers are regions of DNA that bind to specific proteins and enhance the transcription of genes. However, the effects of enhancers need to be restricted to ensure that they do not activate inappropriate transcription of non-target genes.

This is achieved through various mechanisms such as the specificity of the enhancer-protein interactions, the proximity of the enhancer to its target gene, and the presence of insulator sequences that block enhancer activity on non-target genes.

The specificity of enhancer-protein interactions ensures that the enhancer only binds to proteins that are specific to its target gene, thereby preventing it from binding to non-target genes. Additionally, the proximity of the enhancer to its target gene ensures that the effects of the enhancer are limited to that particular gene.

Insulator sequences are DNA elements that block the effects of enhancers on non-target genes by forming a boundary between enhancers and target genes. Insulators act as barriers that prevent the spread of enhancer activity to non-target genes. Therefore, the presence of insulator sequences is crucial in ensuring that the effects of enhancers are restricted to their target genes.

In conclusion, the effects of enhancers are restricted to prevent the inappropriate transcriptional activation of non-target genes. This is achieved through the specificity of enhancer-protein interactions, the proximity of enhancers to their target genes, and the presence of insulator sequences that block enhancer activity on non-target genes.

Answer:

1.Budding 2.I do not know

Explanation:

The number of bands that will be visible on a gel after cleaving all unprotected DNA will depend on various factors such as the size and number of DNA fragments, the type of gel used, and the specific experimental conditions.

In general, DNA cleavage can result in the generation of multiple fragments of varying sizes. These fragments can then be separated on a gel using techniques such as agarose gel electrophoresis or polyacrylamide gel electrophoresis based on their size, with smaller fragments migrating faster through the gel and larger fragments migrating slower.

Assuming that all the unprotected DNA has been cleaved into fragments of different sizes, the number of bands visible on the gel would correspond to the number of different-sized DNA fragments generated. Each distinct size of DNA fragment will appear as a separate band on the gel, which can be visualized using techniques such as DNA staining or radioactive labeling.

Therefore, the total number of bands visible on the gel will depend on how many different-sized fragments were generated by the DNA cleavage, which can vary depending on the experimental conditions and the specific DNA being cleaved. A DNA ladder, which is a mixture of DNA fragments of known sizes, is typically included on the gel as a reference to estimate the sizes of the DNA fragments generated from the cleavage.

Following Hardy-Weinberg equilibrium equations, and considering a diallelic gene, if p = 0.37, then q = 0.63. The frequency of the recessive allele -q- is 0.63.

To answer this question, we will assume Hardy-Weinberg equilibrium.

The Hardy-Weinberg equilibrium is a theory that states that a population in equilibrium will express the same allelic and genotypic frequencies through several generations.

Assuming a diallelic gene,

• The frequency of the dominant allele p(X) is p

• The frequency of the recessive allele p(x) is q

The addition of the allelic frequencies equals 1

p + q = 1.

• p² (Homozygous dominant genotypic frequency),

• 2pq (Heterozygous genotypic frequency),

• q² (Homozygous recessive genotypic frequency).

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.

In the exposed example, we have a diallelic gene. We already know the frequency of the dominant allele (p = 0.37) and now we need to know the frequency of the recessive allele (q = ?). All we need to do is to clear the following equation,

p + q = 1

0.37 + q = 1

q = 1 - 0.37

q = 0.63

The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called gas exchange. This process takes place in the lungs. Oxygen is taken into the body via inhalation and enters the lungs, where it moves across the alveolar walls and into the bloodstream.

At the same time, carbon dioxide, a waste product, moves from the bloodstream across the alveolar walls and is exhaled from the body during exhalation.The lungs are one of the most important organs in the body's respiratory system.

The respiratory system's primary function is to transfer oxygen from the environment to the body's cells while removing carbon dioxide from those cells and returning it to the environment.

The exchange of gases between the atmosphere and the body cells is known as respiration, which occurs in three phases: external respiration, internal respiration, and cellular respiration.

An inflammatory response would result from a jellyfish sting. When a person gets stung by a jellyfish, it triggers an immune response in the body, leading to inflammation at the site of the sting.

Jellyfish tentacles contain specialized cells called cnidocytes, which release venomous threads upon contact. These venomous threads can cause local tissue damage and elicit an immune response. The immune response to a jellyfish sting involves the release of various chemical mediators, such as histamine and prostaglandins. These mediators cause blood vessels to dilate, leading to increased blood flow to the affected area.

They also increase the permeability of blood vessels, allowing immune cells and substances to migrate to the site of injury. Inflammation manifests as redness, swelling, pain, and warmth at the sting site. This response is the body's way of defending against potential pathogens or foreign substances and initiating the healing process. A headache and vomiting, on the other hand, may be associated with various conditions, but they are not directly related to an inflammatory response caused by a jellyfish sting.
