A Pre-mRNA isn't always a mechanism of gene regulation that may take place after transcription is finished in eukaryotes.

Gene expression in eukaryotic cells is regulated via repressors as well as by transcriptional activators. Like their prokaryotic opposite numbers, eukaryotic repressors bind to unique DNA sequences and inhibit transcription.

In particular, gene expression is managed in two ranges. First, transcription is controlled by proscribing the amount of mRNA that is comprised of a selected gene.

Answer:

b

Explanation:

he overall equation for cell respiration is oxygen + glucose → carbon dioxide + water + energy. If we flip this equation in reverse, it will look like the equation for photosynthesis.Cellular respiration and photosynthesis are two interconnected metabolic processes.

Both cellular respiration and photosynthesis are vital to life on Earth. During photosynthesis, plants transform light energy into chemical energy stored in organic compounds. Cellular respiration is a metabolic process that transforms organic compounds into energy (ATP). Photosynthesis converts carbon dioxide and water into glucose and oxygen. In contrast, cell respiration oxidizes glucose to yield ATP while producing carbon dioxide and water.A common misunderstanding is that photosynthesis is the opposite of cellular respiration.

The reactions for photosynthesis and cellular respiration are not exact opposites. Photosynthesis involves the absorption of light by pigments, whereas cellular respiration does not. Cellular respiration requires oxygen and gives off carbon dioxide, whereas photosynthesis requires carbon dioxide and gives off oxygen.

Excess macromolecules are stored in the form of triglycerides in fat cells.

When we consume more calories than our body needs, the excess macromolecules are converted into triglycerides by a process called lipogenesis. These triglycerides are then stored in adipose tissue as a form of energy reserve. When the body needs energy, it can break down these triglycerides through a process called lipolysis. However, if we continue to consume more calories than we burn, these triglyceride stores can become too large, leading to obesity and other health issues. Therefore, maintaining a healthy diet and regular exercise routine is essential for preventing the accumulation of excess triglycerides in the body.

Sexual reproduction increases genetic diversion because there are two parents, unlike in asexual reproduction where there is only one.

Explanation:

During sexual reproduction, gamites come from both parents and mix together to create genes and traits for the offspring. Gamites are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes.

The function of amniotic fluid is protects the embryo against being jostled by movements.

The function of amniotic fluid includes the following:

1. Protects the embryo against being jostled by movements: The amniotic fluid protects the developing fetus from jolts and injuries due to its fluidic environment. As a result, if the mother experiences a fall or sudden movement, the fetus will be shielded by the amniotic fluid, which will absorb the shock. The amniotic fluid maintains a stable temperature, ensuring that the fetus is comfortable and healthy.

2. Absorbs wastes the fetus excretes: The amniotic fluid serves as a waste disposal system for the developing fetus, absorbing and carrying away all of the waste products that the fetus generates. The fetus urinates the fluid into the amniotic sac, and the amniotic fluid carries it away.Apart from these, the amniotic fluid plays a crucial role in fetal development by protecting the developing fetus from physical injury and infection. It also keeps the temperature stable and provides an excellent environment for the fetus to grow and develop healthily.

Explanation:

The skeletal system and the muscular system work together to move the body or body parts. Different types of tissues form the muscular system that and their action on bones controls the movement of the body in vertebrates.

Tendons are tough muscles that attach with the bones and joints allow the movement by contraction of muscle that helps in moving bones from joint. Muscle normally acts by contracting and relaxing in pairs.

For a cell to obtain more sugar the cell must use active transport to pump the sugar inside it .

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration which occur against the concentration gradient . So , it requires cellular energy to achieve this action.

Main function of active transport is involves the movement of molecules from a region of lower concentration to a region of higher concentration with help of energy in form of ATP. examples of active transport include the absorption of glucose in the intestine of the human body and the uptake of minerals or ions into the root hair cells of plants.

Answer:

Inputs---- glucose and oxygen.

Outputs----- ATP, carbondioxide and water.

Explanation:

The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.

Chargaff discovered that in DNA, the number of guanine (G) bases is equal to the number of cytosine (C) bases. This is known as Chargaff's rule and it is essential for the proper pairing of DNA strands during replication.

Chargaff's rules state that in the DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine. Further a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) should exist. This pattern is found in both strands of the DNA.

The right diet for one animal, 180 grams of Mix A and 35 grams of Mix B should be used.

To calculate the amount of each food mix needed to achieve the desired protein and fat content in the animal's diet, we can set up a system of equations based on the given information.

Let's assume x grams of Mix A and y grams of Mix B are used.

The protein content from Mix A can be calculated as 10% of x grams, which is 0.1x grams. Similarly, the protein content from Mix B is 20% of y grams, or 0.2y grams.

The fat content from Mix A is 6% of x grams, or 0.06x grams, and the fat content from Mix B is 2% of y grams, or 0.02y grams.

We need the total protein to be 25 grams and the total fat to be 5 grams.

From the given information, we can set up the following equations:

Protein equation: 0.1x + 0.2y = 25 (equation 1)

Fat equation: 0.06x + 0.02y = 5 (equation 2)

To solve this system of equations, we can use various methods, such as substitution or elimination. Here, we'll use the substitution method.

First, isolate one variable in equation 1. Let's solve for x:

0.1x = 25 - 0.2y

x = (25 - 0.2y) / 0.1

Substitute the value of x in equation 2:

0.06((25 - 0.2y) / 0.1) + 0.02y = 5

Simplify and solve for y:

1.5 - 0.12y + 0.02y = 5

-0.1y = 3.5

y = -3.5 / -0.1

y = 35

Now substitute the value of y back into equation 1:

0.1x + 0.2(35) = 25

0.1x + 7 = 25

0.1x = 18

x = 180

Therefore, to obtain the right diet for one animal, 180 grams of Mix A and 35 grams of Mix B should be used.

The technology that has been commonly utilized by scientists to manipulate heritable information by producing large amounts of identical recombinant DNA molecules is gene cloning.

Gene cloning is the process by which we insert a section of DNA into a cell and then let the cell undergo mitosis, creating copies of that genetic information. Gene cloning is different from organism cloning, which uses an organism's DNA to produce a genetically identical organism because it only produces cells, not an entire organism.

Cloning of any DNA fragment involves four steps in the traditional restriction enzyme digestion and ligation cloning protocols: isolation of the desired DNA (or target DNA ), ligation, transfection, or transformation.

60% of semen is secreted by seminal vesicles. Membranous urethra is component of male reproductive system and testes create sperm.

60% of the semen volume, which has an alkaline pH and contains prostaglandins, is secreted by the seminal vesicles. The membranous urethra is a component of the male reproductive system, whereas the testes are the organs that create sperm.

The seminal vesicles are a pair of glands in males that are situated close to the base of the bladder. By secreting around 60% of the volume of semen, they contribute to its composition. Fructose, proteins, enzymes, and prostaglandins are among the chemicals found in the seminal fluid that the seminal vesicles create. The urethra and female reproductive tract's acidic environment is partially offset by the seminal fluid's alkaline pH, creating a favourable environment for sperm survival and motility. The seminal fluid contains prostaglandins.

Answer:

Due to the increase in surface area, the nutrients move efficiently inside the cell.

Explanation:

The cells need to have a high amount of surface area as compared to their total volume because, with the increase of surface area, the nutrients move efficiently inside the cell. A large surface area to volume ratio indicates that the cell can be efficient in moving nutrients and waste materials around using the process of diffusion but when the volume increases instead of surface area, the efficiency of the cell decreases, and cells won't be able to do its job efficiently.
