Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.

Explanation:
(B) a somatic cell of a male.
(C) a somatic cell of a female.
(D) a sperm cell.
(E) an egg cell
A human cell with 22 autosomes and a Y chromosome is a male sperm cell. Sperm and egg cells contain 23 chromosomes, including one sex chromosome, while other cells typically have 46 chromosomes.
A human cell that contains 22 autosomes and a Y chromosome is (D) a sperm cell. Human cells are normally diploid, meaning they contain 46 chromosomes: 22 pairs of autosomes and a pair of sex chromosomes. Somatic cells (both male and female) have a total of 46 chromosomes, while a zygote, the cell formed after the fusion of an egg and a sperm, is also diploid. However, sperm and egg cells, which are haploid, carry only 23 chromosomes: 22 autosomes and either an X (in the case of an egg cell or a male sperm cell) or a Y (in the case of a male sperm cell) chromosome.

b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.
Exceeding the maximum growth temperature of an organism can lead to the breaking of hydrogen bonds, denaturation of proteins and the over-fluidization of cell membranes.
At temperatures higher than the maximum growth temperature for an organism, d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid. When the temperature exceeds the maximum threshold for an organism, this exerts stress on the cell causing various biological consequences. For instance, hydrogen bonds within molecules can get disrupted, which can lead to protein denaturation. This means that the proteins lose their functional 3-dimensional shape, a process that can sometimes be irreversible. Moreover, excessive heat can increase the fluidity of cellular membranes to an extent such that they cannot function properly anymore, making the cell unviable.

Answer:
The correct answer is production of nerve tissue, which may help in treating paralyzed patients.
Explanation:
Cloning that is developed mainly as a therapy for a disorder is considered as the therapeutic cloning. In this form of cloning, the nucleus from the cell is withdrawn and is kept within a fertilized egg that does not possess a nucleus. It permits the self-cells of the individuals to be utilized in curing the condition, without imparting the threat of presenting foreign cells, which may get rejected.
