Explanation:

The phase of mitosis given by the letter 'C' here is Metaphase.

In the process of mitosis,  a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The term "mitosis" means " threads," and it is referred to the threadlike aspect of chromosomes as the cell prepares to divide. The process of mitosis consists of five morphologically distinct phases prophase, prometaphase, metaphase, anaphase, and telophase.

The metaphase begins as soon as the prometaphase ends and then the chromosomes align along the cell equator. Every chromosome has at least two microtubules extending from its kinetochore with at least one microtubule hitched to each pole. At this particular juncture, the pressure within the cell becomes balanced, and the chromosomes no longer move back and forth. In addition, the spindle is now complete , and three groups of spindle microtubules are evident. Kinetochore microtubules attach the chromosomes to the spindle pole; interpolar microtubules extend from the spindle pole across the equator, nearly to the contrary spindle pole; and astral microtubules draw out from the spindle pole upto the cell membrane. One of the cell cycle checkpoints happens during prometaphase and metaphase.

Lysosome-protein synthesis is mismatched.

'What are lysosomes?'

Proteins, nucleic acids, carbohydrates, and lipids can all be broken down by the variety of enzymes found in lysosomes, membrane-enclosed organelles. Lysosomes serve as the cell's digestive system, breaking down substances taken in from the outside and breaking down unused parts of the cell. Lysosomes are typically pictured as thick, spherical vacuoles, however due to variances in the substances that have been taken up for digestion, they can exhibit significant size and shape diversity. Thus, lysosomes are morphologically varied organelles that are united by the process of digesting intracellular substances.

The two ways to increase the energy of a wave are increase the amplitude and increase the frequency. The correct option is B.

A wave is a propagating dynamic disturbance of one or more quantities in physics, mathematics, and related fields.

Periodic waves occur when quantities oscillate repeatedly about an equilibrium value at some frequency.

The amplitude and frequency of a wave are related in such a way that they are inversely proportional. With increasing frequency, the amplitude decreases. As the frequency decreases, the amplitude increases.

The amount of energy in a wave is determined by its height, wavelength, and the distance over which it breaks.

When equal wavelengths are used, a wave with a larger amplitude will release more energy when it returns to sea level than a wave with a smaller amplitude.

Thus, the correct option is B.

Tumor growth is a process associated with the expression of oncogenic genes

Explanation:

The tumor cells often share oncogenic receptors that are expressed during oncogenesis. For example, it has been shown that the epidermal growth factor receptor is often mutated in brain cancer cells, thereby encoding an oncogenic that is overactive. These receptors are responsive to stimulus of nearby cells and thus act as effectors that amplify tumorigenic signals. In consequence, during tumor progression, tumorigenic effector cells have an uncontrolled proliferation and antiapoptotic signals are predominant. The nucleus in the cell functions as a control center where tumor suppressor genes are transcribed to fight against such oncogenic cells.

By conducting twin studies, adoption studies, or using animal models to separate genetic and environmental influences on the trait.

Researchers employ twin, adoption, and animal models to evaluate if a feature is inherited or environmental. Twin studies compare identical (100%) and fraternal (50%) twins for a certain attribute. Identical twins are more similar than fraternal twins, suggesting a stronger genetic effect.

Adoption studies compare biological and adoptive households. If the adopted person and their biological family share a characteristic, genetics are involved. If the attribute is more comparable between the adopted person and their adoptive family, it suggests environmental impact.

Researchers can explore inheritance patterns by carefully breeding animals with specified features. Scientists can determine how genetics and environment affect a characteristic by combining these strategies.

Answer:

Explanation:

When considering the inheritance of traits such as coat color in animals, there are several ways in which black and white offspring can be produced. One possible scenario involves a cross between two individuals with heterozygous genotypes for coat color, meaning that each parent carries both a dominant and recessive allele for coat color. In this case, the offspring have a 25% chance of inheriting two dominant alleles and being completely black, a 50% chance of inheriting one dominant and one recessive allele and having a black and white spotted coat, and a 25% chance of inheriting two recessive alleles and being completely white. Other combinations of parental genotypes can also result in a mixture of black and white offspring, depending on the specific genetic inheritance pattern involved.

The given statement "The three categories of neurons are called neurons, neurons, and interneurons" is B.  False because  The three categories of neurons are  called sensory neurons, motor neurons, and interneurons.

Sensory neurons are responsible for transmitting sensory information from the body's tissues and organs to the brain and spinal cord. Motor neurons, on the other hand, are responsible for transmitting signals from the brain and spinal cord to the muscles and glands in the body, allowing for movement and other bodily functions. Finally, interneurons are responsible for connecting sensory and motor neurons, allowing for communication and coordination between the two.

It is important to note that these three categories are not mutually exclusive, as some neurons can have characteristics of multiple categories. For example, some sensory neurons can also act as interneurons, transmitting signals between different sensory neurons or between sensory and motor neurons. Similarly, some motor neurons can also receive sensory input, allowing for fine control of movement.

In summary, the three categories of neurons are  called sensory neurons, motor neurons, and interneurons, and they play important roles in allowing for communication and coordination within the nervous system. Therefore the correct option is B

Answer:

inplant

Explanation:

The answer choice least likely to result in a nonfunctional polypeptide is a mutation in an intron. This is because introns are non-coding regions of DNA and their mutations generally do not affect the resulting polypeptide.

A non-synonymous mutation is least likely to result in a nonfunctional polypeptide, as it only changes one amino acid in the polypeptide sequence. A missense mutation also changes one amino acid, but it may affect the function of the resulting protein depending on the location of the mutation. A nonsense mutation creates a premature stop codon, resulting in a truncated and likely nonfunctional polypeptide. A mutation in an intron may affect splicing and alter the resulting polypeptide sequence. A mutation to the splice donor acceptor site may also affect splicing and alter the resulting polypeptide sequence.

The substance, needed for protein synthesis, that is carried into a leaf from the stem is nitrate. Nitrate is an essential nutrient that plants use to produce amino acids and proteins. It is a part of the nitrogen cycle and is used in chloroplasts to create essential proteins.Option B is correct

The process of protein synthesis takes place in chloroplasts of the leaves of plants where nitrogen, along with other elements, is utilized to produce proteins. Nitrogen, in the form of nitrate, is an essential element required by the plant for the synthesis of amino acids and proteins.

Plants obtain nitrate through the soil from the water they absorb through their roots. It is transported from the roots to the leaves through the xylem vessels, which form a continuous pipeline from the roots to the stem and leaves of the plant. The process of protein synthesis is important for the growth and development of plants.

It is essential for the production of enzymes, hormones, and structural components such as cell walls and membranes. Nitrate is, therefore, a critical substance for protein synthesis and the growth and development of plants. Option B is correct
