A. the same

B.twice as much

c. one-half as much

D. one-fourth as much

One-half as much. Thus, option "C" is correct.

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much as the information contained in a normal human body cell (46 chromosomes).

Sperm cells are produced during meiosis, a specialized division process that reduces the number of chromosomes in half, generating haploid daughter cells.

Answer:

heart disease, diabetes, hemophilia and AIDS.

Explanation:

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

The genotypes and phenotypes their offsprings can have include only free lobes and attached hair.

This is defined as the genetic constituent of an organism while phenotype represents the physical characteristics.

Dd and Ee when crossed will give DE, De, dE and de which means that the genotype will be 1 homozygous dominant,2 heterozygous and 1 homozygous recessive for free lobes and attached hair.

The probability = number of favorable outcome/ total number of outcome.

The total number of outcome = 4

The probability for 1 homozygous dominant,2 heterozygous and 1 homozygous recessive is therefore 1/4 , 1/2 and 1/4 respectively.

The reduction of food sources results in the competition of food resources in the aquatic ecosystem.

Severe storm occurs in the water which adversely affected the aquatic ecosystem. This change can affect the competition of food resources in your aquatic ecosystem because the food on which the aquatic animals feed is destroyed by the storm. So less food is available for the organisms which leads to competition between organisms.

So we can conclude that the reduction of food sources results in the competition of food resources in the aquatic ecosystem.

Answer:

B. cellular respiration

Explanation:

The process of transcription related to protein synthesis and gene expression as in this a portion of a DNA molecule is read to produce an mRNA molecule. Thus, the correct option is D.

Transcription is the process through which a cell makes an mRNA (messenger RNA) copy of a piece of the DNA segment. This RNA copy called as messenger RNA (mRNA), carries the genetic information which is needed to synthesize proteins in a cell. The messenger RNA carries the information from the DNA sequence in the nucleus of the cell to the cytoplasm, where the proteins are synthesized.

A portion of a DNA molecule is read to produce an mRNA molecule. It is the best explains the process of transcription as it relates to protein synthesis and gene expression.

Explanation:

Each sentence describes a different form of energy:

An electromagnetic spectrum is a set of frequencies and wavelengths over which an electromagnetic wave can be spread (extends).

From smallest to longest wavelength (highest to lowest frequency), the electromagnetic spectrum consists of the following types of energy:

Type of energy:

Each phrase in science describes a different form of energy:

1. Violet light has the shortest wavelength of visible light.

Visible light has a wavelength of 380 to 450 nanometers.

2. Infrared radiations are energy that can be felt as heat but cannot be seen.

Infrared radiation is a form of energy that the human body perceives as heat but that cannot be seen since it is outside the visible light range.

3. Ultraviolet radiations are short, invisible rays that might cause eye injury.

Ultraviolet light, which is mostly produced by the Sun, has the potential to harm the eyes.

4. Red light is the visible light with the longest wavelength.

Red light has a wavelength of 620 to 750 nanometers.

Explanation:

Blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.

Aerobic respiration is respiration which occurs in the presence of oxygen.

Anaerobic respiration is a respiration which occurs in the absence of oxygen

During aerobic respiration in humans, the end-product is acetylcoA while in anaerobic respiration, the end product is lactic acid.

A sprinter undergoes mostly anaerobic respiration and produces lactic acid, while a marathon runner undergoes mostly  aerobic respiration and produces less lactic acid.

Therefore, blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.

Answer:

While exercising, the muscles need additional energy as the breathing rate and volume of each breath increase to bring more oxygen into the body and remove the carbon dioxide produced. If insufficient oxygen is available to the muscles, for instance, the exercise is vigorous and/or prolonged, the heart and lungs are unable to supply sufficient oxygen. Muscles begin to respire anaerobically. Lactic acid is produced from glucose, instead of carbon dioxide and water. Muscles continue to contract, but less efficiently. When a period of exercise is over, lactic acid must be removed, because the body's tolerance to lactic acid is limited. These processes require oxygen. This is why, when the period of activity is over, a person’s breathing rate and heart rate do not return to normal straight away.

It's an "Inherited Blood disorder"

Explanation:

what is "Sickle cell anaemia"?

A group of disorders that cause red blood cells to become misshapen and break down.

With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape.

Sickle cell disease is caused by inheriting the sickle cell gene.

The sickle cells die early, which causes a constant shortage of red blood cells. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems such infection, acute chest syndrome and stroke.

Explanation in brief:

Anemia has three main causes:

blood loss, lack of red blood cell production, and high rates of red blood cell destruction.
