Intrinsic factor, which is secreted by the parietal cells, is necessary for vitamin b12 absorption.

Vitamin B12 is essential for many metabolic processes, including the production of red blood cells and DNA synthesis, as well as the proper functioning of the nervous system.

Intrinsic factor is a glycoprotein produced in the stomach that binds to vitamin B12 and helps it to be absorbed in the small intestine. Without intrinsic factor, the body is unable to absorb vitamin B12, leading to a deficiency and a range of health problems.

Therefore, it is clear that intrinsic factor is necessary for vitamin B12 absorption, and without it, the body would not be able to utilize this essential nutrient.

The mutation in the beta-globin allele into the sickle cell allele can be detected by Denaturing gradient gel electrophoresis or DGGE.

It uses electrophoresis to find single base alterations in a DNA segment. Double-stranded DNA is subjected to an increasing denaturing environment in a denaturing gradient acrylamide gel and will melt in distinct regions known as "melting domains." These domains' melting point (Tm) varies depending on the sequence.

The DNA will partially melt when the lowest melting domain's Tm is reached, resulting in branched molecules. DNA loses some of its mobility in a polyacrylamide gel when it partially melts. The presence of a mutation will change the DNA's melting profile when compared to wild type because the Tm of each melting domain is sequence-specific. DNA with mutations will experience mobility shifts at various locations in the gel compared to the wild type. If the fragment completely loses its genetic makeup, migration once more depends on size.

Hence, difference in normal and mutant DNA sequence can be observed in gel.

Cells utilize the genetic information contained in DNA as a living library of instructions to carry out life's essential tasks. In each cell, catalysts look for the relevant information in this library and use it to create new proteins that make up the cell's structures, drive its biochemical processes, and are occasionally produced for export. Although the genetic code in every cell of a multicellular creature is the same, functionally distinct cells within the organism use diverse sets of catalysts to express only particular parts of these instructions in order to carry out the duties of life.

The number of chromosomes during mitosis of a fruit fly is 8 while in human cells, there are 46 chromosomes during mitosis and 23 chromosomes during meiosis

Mitosis is a type of cell division that produces two identical daughter cells from a single parent cell. It is a process by which a cell replicates its genetic material and divides into two daughter cells. During mitosis, the chromosomes in the nucleus are duplicated, and the nucleus divides into two daughter nuclei. This process of mitosis is responsible for the growth and development of organisms, as well as for the maintenance of tissue.

Meiosis is the process of cell division that produces reproductive cells (gametes) with half the number of chromosomes as the parent cell. During meiosis, the chromosomes in the nucleus are duplicated and then split into four daughter cells. This process of meiosis is responsible for the formation of eggs and sperm, and is essential for sexual reproduction.

The alternative form or variations of a gene are referred to as "alleles." One allele for each autosomal gene is inherited from each parent, and we frequently categorise the alleles. They are typically referred to as wild-type, mutant, aberrant, or normal alleles.

Answer:

Explanation:

Here is a completed Punnett square showing a cross between a pink (RW) flower and a red (RR) one:

REFER TO IMAGE

In this cross, the pink flower is heterozygous for the trait, with one dominant allele (R) and one recessive allele (W). The red flower is homozygous dominant, with two copies of the dominant allele (RR).

The Punnett square shows that the offspring of this cross will have a 50% chance of inheriting the dominant allele from each parent and being red (RR), and a 50% chance of inheriting one dominant allele and one recessive allele and being pink (RW). There is no chance that any of the offspring will be white (WW), as this is a recessive trait and both parents have at least one dominant allele.

The probability of albinism in the offspring of a cross between two mice with aabb alleles is 0%. Albinism is a genetic condition characterized by the absence of pigment in the skin, hair, and eyes. It is caused by mutations in genes that produce the pigment melanin.

In the cross between two mice with aabb alleles, all of the offspring will be heterozygous (Aa) for the trait that determines the production of melanin. Heterozygotes (Aa) produce some melanin and are not albino. Therefore, none of the offspring of this cross will be albino. In summary, the probability of albinism in the offspring of a cross between two mice with aabb alleles is 0%.

In the kidney, reabsorption is the movement of water and solute molecules from the tubule back into the bloodstream. It specifically occurs in the proximal part of the tubule. The reabsorption happens using both secondary active transport and isotonically.

Reabsorption allows various useful solutes (such as amino acids and glucose), salt, and water that already passed Bowman's capsule to return into the body's circulation instead of being thrown away as waste via urine.
