Explanation:

The allele that determines the phenotype with respect to a particular gene is the option A. dominant allele.

In genetics, alleles are alternate forms of a gene that occupy the same position (locus) on a chromosome. Each individual inherits two alleles for each gene, one from each parent. The interaction between these alleles determines the expression of the gene and ultimately the phenotype, which refers to the observable characteristics or traits of an organism.

A dominant allele is one that exerts its effect even if there is only one copy present in the individual's genotype. It masks the effect of the recessive allele, which is only expressed when two copies of the recessive allele are present.

When an individual possesses a dominant allele for a particular gene, it determines the phenotype associated with that gene. This means that the trait associated with the dominant allele will be expressed, regardless of whether the other allele in the pair is dominant or recessive. Therefore, the correct answer is option A.

Answer:

20 chromosomes.

Explanation:

gametes are sex cells. they are called haploid cells because they get only half number of chromosomes from the parent cell.

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype  tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

Answer:

breathing

Explanation:

It is through biological reproduction that new, unique species are produced. The two types of reproduction are sexual and asexual.

Two parents contribute genetic material during sexual reproduction to create unique offspring1. Gametes (sperm and egg) from two parents combine during sexual reproduction to create a zygote. After that, the zygote goes through cell division and differentiation to develop into an embryo.

A zygote is what?

A zygote is a eukaryotic cell created when two gametes fertilize one another. To put it another way, it is the first cell created when two gamete cells (egg and sperm) unite during sexual reproduction. The zygote has all the genetic material needed to develop into a new person.

Asexual reproduction involves the creation of genetically identical offspring by a single parent. Many processes, including binary fission, budding, fragmentation, and vegetative propagation, can lead to asexual reproduction.

Describe binary fission.

Asexual reproduction known as binary fission occurs when a single creature splits into two separate organisms4. Bacteria and other prokaryotic species frequently exhibit this process.

The organism separates into two pieces (cytokinesis) after duplicating its genetic material (DNA), with each new organism acquiring one copy of DNA.

Answer: Telescope

Explanation: Galileo pioneered the use of the telescope for observing the night sky. His discoveries undermined traditional ideas about a perfect and unchanging cosmos with the Earth at its centre.

The area around a charge in which the electric force is experienced by other charged objects is the electric field.

The electric field is a property of the space around a charged object and is created by the presence of that charge. Any other charged object placed within the electric field will experience a force exerted on it due to the interactions between the electric charges.

The electric field can be thought of as a field of influence that extends throughout space, representing the force that would be experienced by a positive test charge placed at any given point within the field. The strength and direction of the electric field depend on the magnitude and sign of the charge creating the field. Electric field lines, which are used to visualize the electric field, point away from positive charges and towards negative charges.

The electric field plays a crucial role in understanding and describing the behavior of charged particles and the interactions between them. It is a fundamental concept in electromagnetism and has applications in various fields, including electronics, electrical engineering, and physics.

Answer:

The correct answer is option b. "repressible gene expression".

Explanation:

The trp operon is a classic example of a repressible gene expression. The trp operon controls the biosynthesis of tryptophan from an initial precursor by encoding five genes that translate to three enzymes. These enzymes act as regulators and tryptophan itself acts as the final regulator. Tryptophan inhibits its own production when it binds to the transcription regulator, therefore it is an example of a repressible gene expression.

Answer:

NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.

During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.

In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.

Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.

Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.

In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

An intromittent organ is any external organ of a male organism that is specialized to deliver sperm during copulation. Intromittent organs are found most often in terrestrial species, as most non-mammalian aquatic species fertilize their eggs externally, although there are exceptions. For many species in the animal kingdom, the male intromittent organ is a hallmark characteristic of internal fertilization.

The "exfoliation" or "shedding" of milk teeth is the name of the procedure.
