Explanation:

Approximately 50% of mitotic cells would be radiolabeled 9 hours after the pulse in a pulse-chase experiment performed with radioactive thymidine on an asynchronous culture of cells.

During a pulse-chase experiment, a radioactive thymidine is added to the culture medium for a short period of time, referred to as the "pulse." The radioactive thymidine gets incorporated into newly synthesized DNA molecules. After the pulse, the cells are allowed to continue growing in a non-radioactive thymidine-containing medium, known as the "chase" period. This allows the labeled DNA to be diluted among the total DNA pool of the cells.

In an asynchronous culture, cells are in different stages of the cell cycle, including interphase and mitosis. However, during mitosis, DNA synthesis is temporarily halted, as the cell prepares for cell division. Therefore, mitotic cells that were in the process of synthesizing DNA during the pulse would not incorporate the radioactive thymidine.

Considering the time frame of 9 hours after the pulse, most of the labeled DNA would have been diluted in the non-radioactive thymidine-containing medium during the chase period. Consequently, the percentage of radiolabeled mitotic cells at this time point would be minimal. It is estimated that approximately 50% of the mitotic cells would still retain the label, as they had not undergone DNA synthesis during the pulse phase.

Pulse-chase experiments are valuable tools in molecular biology and cell biology research. They allow scientists to study the dynamics of cellular processes such as DNA replication, protein synthesis, and trafficking. By using a radioactive or fluorescently labeled precursor molecule during the pulse phase, researchers can track the movement and fate of these molecules within cells over time.

Explanation:because salt has been taken from the ocean only

The enzyme required to synthesize mRNA is called RNA polymerase.

The enzyme required to synthesize mRNA is called RNA polymerase. RNA polymerase plays a crucial role in the process of transcription, which is the synthesis of RNA molecules using a DNA template.

During transcription, RNA polymerase binds to the DNA molecule at a specific region called the promoter. It then unwinds the DNA double helix and separates the DNA strands.

The RNA polymerase uses one of the DNA strands, known as the template strand, as a guide to synthesize a complementary RNA molecule.

As the RNA polymerase moves along the DNA template, it adds ribonucleotides to the growing RNA chain, following the rules of base pairing. Adenine (A) pairs with uracil (U), cytosine (C) pairs with guanine (G), and so on.

This process continues until the RNA polymerase reaches a termination sequence, which signals the end of transcription.

RNA polymerase is highly specific and capable of recognizing different types of promoters and regulatory elements to initiate transcription at specific locations within the genome.

It ensures accurate and controlled synthesis of mRNA, which serves as a template for protein synthesis during translation.

In summary, the enzyme responsible for synthesizing mRNA is RNA polymerase, making option (c) the correct answer. RNA polymerase plays a vital role in gene expression by transcribing the genetic information encoded in DNA into functional RNA molecules.

Two parents that are heterozygous for a recessive disease-causing allele (Aa x Aa). To find the probability that both of their children are affected by the recessive disease, we need to calculate the probability of one child being affected and then square it since we want the probability for two children which for aa comes (1/4) * (1/4), that is 0.0625.

1. Determine the possible offspring genotypes using a Punnett square:

  A  |  a
-----------
A | AA | Aa
-----------
a | Aa | aa

Affected genotype : aa

Unaffected genotype : Aa (heterozygous) , AA

2. To calculate the probability of one child having the mutant disease-causing allele (aa) from the Punnett square:
  There are 4 outcomes, and 1 of them has the aa genotype, so the probability is 1/4.

3. To determine the probability of both children being affected:
  Square the probability for one child (1/4) * (1/4) = 1/16.

So, the probability that both children are affected by the recessive disease is 0.0625 (to 4 decimal places).

The tension in the rope is calculated as 33.7 N.

Weight of sled and fossil, w = 972 N Inclination angle of slope, θ = 19.8°

Speed of sled, v = 1.92 m/s

Coefficient of kinetic friction between sled runners and snow, μ = 0.107

To find:

Tension in the rope, T The forces acting on the sled are the gravitational force (Fg), the normal force (Fn) and the force of friction (Ff). The normal force is perpendicular to the slope and equal to the component of the gravitational force perpendicular to the slope. The force of friction is parallel to the slope and opposite the direction of motion.

The net force acting on the sled is given by the expression:

F net = ma

Since the sled moves with constant velocity, a = 0.

Therefore, F net = 0. F net = Fg sinθ - Ff = 0⇒ Fg sinθ = Ff

Since the speed of sled is constant, work done by tension in the rope is equal to work done by frictional force.

Hence, T = Ff = μFn

Where F n = Fg cosθ = w cosθ

Putting all the values,

T = μw cos θ sinθ= sin 19.8°cos 19.8°= 0.3365T = 0.107 × 972 × 0.3365T = 33.7 N

The rope is 33.7 N. The given problem is related to the tension in the rope. The tension in the rope is calculated as 33.7 N.

To bring down the fossil safely down the slope, the tension in the rope is 33.7 N. The gravitational force is acting perpendicular to the slope and the force of friction is acting parallel to the slope. The normal force is the component of gravitational force acting perpendicular to the slope. The sled moves down the slope with a constant velocity. The force acting on the sled is equal and opposite to the force of tension in the rope. The force of friction is given by the expression,

Ff = μFn,

where Fn = Fg cosθ = w cosθ.

Therefore, the tension in the rope is calculated as 33.7 N.

To bring down the fossil safely down the slope, the tension in the rope must be 33.7 N.

Explanation:

The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain \(pH\) value (different for each amino acid) nearly all the amino acid molecules exist as zwitter-ions. If acid is added to a solution containing the zwitter-ion, the carboxylate group captures a hydrogen (\(H^+\)) ion, and the amino acid becomes positively charged. If base is added, ion removal of the \(H^+\) ion from the amino group of the zwitter-ion produces a negatively charged amino acid. In both circumstances, the amino acid acts to maintain the pH of the system—that is, to remove the added acid \((H^+)\) or base \((OH^-)\) from solution.

A reason for the difference in the lactic acid threshold of athletes P and Q is that P is more physically fit and trained than Q.

The level of effort at which lactic acid, or lactate, starts to build up in the blood is known as the lactic acid threshold. The energy needed for low-intensity exercise can be entirely produced by using oxygen-dependent mechanisms (aerobic), and this can go on forever.

The lactic acid threshold is often reached by well-trained runners at 90% of their maximum heart rate and at a pace akin to that of a half-marathon. The lactate threshold typically occurs for less seasoned runners somewhere below 90% of the maximum heart rate.

One can raise the lactic acid threshold by running intervals. Interval training involves frequently exceeding your lactate threshold while jogging a predetermined distance at your highest speed, followed by a recovery pause. For instance, you might decide to sprint 400 meters around a track.

After considering the given data and reviewing the valid articles and information  concerning DNA we conclude that the statement is true.

All organic forms of life possess a division of labor within them, metabolism (chemical activity), and replication (genetic code). DNA is the key to the genetic code in most organisms living today and serves as an instruction manual that makes it possible to create a living organism.
Therefore , DNA is helpless without its counterpart, metabolism. Metabolism is the set of chemical reactions that occur in living organisms to maintain life. The discovery of RNA in the 1960s did not help alleviate this problem.

RNA is a relative of DNA but can only perform metabolism and not replication in an organism. This has led some scientists to conclude that RNA is not useful for understanding the origins of life.
