nonsense mutation will cause translation to stop.

Cut off Codon

In DNA or messenger RNA (mRNA), a stop codon is a trinucleotide sequence of three nucleotides that instructs the cell to stop production of proteins. The number of trinucleotide codons is 64. 3 stop codons are present, and 61 define amino acids (i.e., UAA, UAG and UGA).

A DNA change that causes a protein to cease or end its translation earlier than predicted is known as a nonsense mutation or its synonym, a stop mutation. This is a frequent type of mutation that affects both humans and other animals and results in the expression of a protein that is either truncated or ineffective.

Genetic flow is a mechanism of evolution wherein allele frequencies of a populace extrude over generations because of chance .

Genetic flow happens in all populations of non-endless size, however its outcomes are most powerful in small populations. Genetic flow can also additionally bring about the lack of a few alleles (together with useful ones) and the fixation, or upward thrust to, percent frequency, of different alleles.

Genetic flow could have main outcomes while a populace is sharply contracted via way of means of a herbal disaster (bottleneck effect) or while a small institution splits off from the principle populace to determined a colony (founder effect).

In an countless populace, we anticipate directional choice to sooner or later restoration an effective allele, however this could now no longer always manifest in a finite populace, because the outcomes of waft can triumph over the outcomes of choice if choice is susceptible and/or the populace is small.

Corn kernels' color and shape are coded by diallelic genes expressing complete dominance. The genotype of individuals carrying Yellow kernels and a smooth shape phenotype can be either ppSS or ppSs.

Complete dominance refers to the inheritance pattern in which the dominant allele of a gene completely masks the expression of the recessive allele.

The presence of at least one dominant allele is enough to express the dominant trait. This becomes evident in heterozygous individuals.

In the exposed example, two traits are involved. One of them is the kernel color and the other one is the kernel shape.

Genes coding for each of the traits express complete dominance,

If a corn plant had Yellow kernels and a smooth seed shape, it is expressing the recessive phenotype for color (pp) and the dominant phenotype for shape (SS or Ss), so the possible genotypes are,

The absence of special food and water conducting system restricts the body size in algae, liverworts and mosses.

Algae- The term "algae" refers to a class of mainly watery, photosynthetic, & nucleus-bearing organisms which lack the real roots, stems, and leaves of plants as well as their specialized multicellular reproductive structures.

Mosses- Mosses belong to the group of land plants called Bryophyta and are non-vascular plants. They are herbaceous (non-woody) tiny plants (some few centimeters tall) that primarily absorb nutrients and water via their leaves and use light and carbon dioxide to produce food through photosynthesis.

Liverworts- Small flowerless plants known as liverworts have thallus structures that resemble the lobes of a lobed liver. Insects and other small invertebrates depend on the 6000–8000 species of liverworts that are thought to exist.

The given question is incomplete, find below the complete question,

Respiration is the process of using oxygen to release ATP from glucose. It happens in all animals.

Nucleotides are composed of a sugar molecule (ribose in RNA and deoxyribose in DNA), a phosphate group and a nitrogen-containing base (which can be Adenine, Thymine, Guanine and Cytosine in the case of a DNA). Of those three parts, the only one that changes (and therefore identifies the nucleotide) is the nitrogen containing-base. Therefore, the correct answer is C. base.

Answer:  Meristimetic tissue continues to divide and help the growth of a plant. Permanent tissue consists of plant cells that no longer divide.

Explanation: Trust me.

Meristematic tissue

The tissues (group of cells) which undergoes repeated cell division. At the tip of the plant, there is apical meristem. Those tissue helps the plant to grow longer. If the apical meristem is cuts accidentally, then the plant no longer grow and dies.

Permanent tissue

The tissues (group of cells) which does not undergo repeated cell division. The middle portion of the plant cells is permanent tissue.

Overall the plant growth depends on the apical meristematic cells.

Regulating the body temperature happens through the process of thermoregulation. One system that is responsible for this is the excretory system. This process is an example of negative feedback. The body temperature tends to fluctuate within a normal range. So, the brain's control system and other parts of the body monitor this fluctuation and react to deviations from homeostasis.

Plants with chloroplasts carrying out Calvin cycle but unable to carry out light-dependent reactions could not carry out photosynthesis because to produce sugars, the light dependent reactions are essential in order to produce ATP and NADPH.

Calvin cycle is the light-independent reaction that is performed with the help of products from light dependent reactions. The Calvin cycle is accomplished in three steps: Carbon fixation, reduction and regeneration. The product of Calvin cycle is triose phosphate which is further used in glucose production.

Light dependent reactions are those that involved in the production of ATP and NADPH through a series of electron transporters. These ATP and NADPH are therefore used for synthesis of glucose.
