What is one of the most important decisions we have to make in our life?.

Somatic cells and zygote are diploid whereas germ cell, sperm cell, gamete, egg cell are all haploid.

A cell with a single set of chromosomes is called haploid. The number of chromosomes in sperm or egg cells, often known as gametes, is also referred to as haploid. In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid.

Human somatic cells are diploid, meaning they have 46 chromosomes, 22 pairs of autosomes, and a pair of sex chromosomes. A diploid cell is one that has two copies of each chromosome.

Differential treatment on the basis of gender is also known as  gender discrimination

Women make their claims for benefits as spouses and carers, whilst males do so as family providers and earners. Gender differentiation is tied to separate programs for labor market and family demands, structuring benefits claims. The gap between the benefits received by men and women is known as gender inequality.

An individual's internal and unique experience of gender is their gender identity. It is the perception of a person as being a woman, a man, neither, both, or somewhere else on the gender continuum. A person's gender identity could be the same as or different from the sex they were given at birth.

Incomplete dominance and codominance are two different patterns of control that could exist for a single gene with two alleles rather than complete dominance (i.e., other than dominant/recessive).

Incomplete dominance is a genetic phenomenon in which both alleles are expressed in the phenotype in a similar way that the genetic phenomenon of codominance. However, incomplete dominance denoted the higher expression of a gene variant or allele over another, while codominance involves the expression of both alleles in an equivalent manner.

For example, the expression of the A and B alleles in the blood allele system is a case of codominance.

Therefore, with this data, we can see that incomplete dominance and codominance are two different genetic phenomena that involve the expression of alleles in a single locus in a different manner when compared to complete dominance.

The option (D) is correct. Refraction occurs most frequently over ocean trenches or valleys.

Refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.

Moreover, light waves change speed when they pass across the boundary between two substances with a different density , such as air and glass. This causes them to change direction.

Therefore, the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.

Rick and Ronda can have normally- pigmented children in the ratio 1 normal: 1 albino.

What is albinism?

The rare genetic disease known as albinism results in pale or colourless skin, hair, or eyes. An error in one of the several genes that make or distribute melanin, the pigment that gives skin, eyes, and hair their colour, is the root cause of albinism. Melanin production could be absent or drastically diminished as a result of the defect.

A dominant allele, which can come from just one parent, causes a dominant phenotype in those who possess one copy of the gene. A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype. One dominant and one recessive allele for a gene will result in a person with the dominant phenotype.

Being an autosomal recessive condition, albinism only manifests in homozygous recessive genotypes. Since the recessive gene is concealed by the presence of a healthy dominant gene, the heterozygous genotype will be normal but act as a carrier. The query said that the father of the normal pigmented man was an albino (aa). The man has a normal phenotype but an Aa genotype, indicating that he acquired the afflicted gene from his father but that it is hidden by the presence of the dominant allele (A) (carrier).

The pharynx joins the throat's larynx and esophagus to the mouth. The epiglottis, often known as the flap-like structure at the end of the pharynx, is there. When eating, the flap moves to one side; when breathing, it moves to the opposite side.

At the back of the nose and mouth, in the pharynx (FAR-inks), or throat, the two airway openings—the nasal cavity and the mouth—meet. Because it carries both food and air, the pharynx is a component of the respiratory system as well as the digestive system. The respiratory system not only aids in breathing but also stops hazardous substances from entering the body when eating, sneezing, or coughing. The pharynx, also known as the throat, is a flexible muscular tube with a funnel-like form that carries air from the mouth and nose to the trachea, also known as the windpipe. It also joins the larynx, esophagus, and nasal and oral canals.

Both the respiratory and digestive systems depend on the pharynx. Air can move from the nasal cavity to the lungs, larynx, and trachea thanks to it. The epiglottis is located in the nasopharynx, a region of the throat. Air is kept out of the digestive system by covering the esophageal opening.

b) Nucleus, ribosome, ER, Golgi complex

Explanation:

"B" is correct because, with protein production, DNA must first be transcripted to RNA in the nucleus, then the RNA travels to a ribosome at the ER to start translation (RNA to amino acid sequence). Finally, it is sent to the Golgi complex to be further processed and/or sorted to be transported to its destination (in this case, it will be sorted to be transported to the cell membrane).

"C" is incorrect: the mitochondria, cytoskeleton, and lysosome do not play a direct role in protein synthesis.

In meiosis, each gamete receives one allele according to the law of segregation.

Each gamete inherits one allele from each parent for each gene, in accordance with the Law of Segregation.

The gamete acquires one copy of each allele from each parent after each parent's two copies of each allele are split apart during meiosis (for a total of two alleles).

Answer:  It's A

Explanation:

RNA polymerase is responsible for the synthesis of RNA from DNA template. In order for specific cyclins to be expressed, RNA polymerase must first bind to the promoter region of the gene encoding the cyclin.

Once bound, RNA polymerase will begin to transcribe the gene into RNA. The RNA produced by RNA polymerase can then be translated into protein, which will go on to perform the function of the cyclin. Cyclin is a protein that regulates the cell cycle. It does this by binding to and activating enzymes that control cell division.

Cyclin is produced in response to signals that tell the cell it is time to divide. These signals can come from other cells in the body, or from the environment. Once cyclin is produced, it binds to enzymes that control cell division. These enzymes are called cyclin-dependent kinases (CDKs). CDKs phosphorylate (add a phosphate group to) other proteins that control cell division. This phosphorylation activates these proteins, and the cell begins to divide.
