The characteristics formed during interphase, attached to one another by cohesin and they are replicas of a single chromosome correspond to sister chromatids (Options 1, 2 and 7).

Sister chromatids are two identical copies of a given chromosome, which are attached by specific proteins at the centromere level. These copies are generated during the interphase (S synthesis phase) of the cell division (either mitosis or meiosis).

Therefore, with this data, we can see those sister chromatids are identical to each other and they are generated during the interphase of the cell division process.

Due to independent assortment, the possible genetic make-up of gametes produced by this organism is TS, tS, Ts, ts.

Independent Assortment- According to Mendel's independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele with one gene doesn't really affect the allele for another gene that a gamete acquires.

Gametes- An individual's reproductive cells are called gametes. They are additionally known as sex cells. Male gametes are referred to as sperm, whereas female gametes are referred to as ova or egg cells. Each haploid cell that makes up a gamete has one set of chromosomes.

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.

All somatic cells contain the same genes, the only difference among them is on what genes are expressed. Therefore, this statement is true.

Albedo is decreasing as the earth moves back towards the sun.

This is because the heat generated from the sun makes the ice caps melt.
Snow and ice reflect a lot of the sun’s energy back into space. The darker oceans absorb energy, which warms the water. Oceans help keep the Earth warm because they absorb a lot of heat (approximately 90%).
This warming increases water vapour, which acts as a greenhouse gas and helps to keep temperatures within ranges humans have largely taken for granted for millennia.

What is Albedo?
Albedo is a measure of the reflectivity of a surface. The albedo effect when applied to the Earth is a measure of how much of the Sun's energy is reflected back into space. Overall, the Earth's albedo has a cooling effect.

Hence, the Albedo is decreasing as the Earth moves back towards the Sun.

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.

The circulatory system is composed of blood vessels, including arteries, veins, and capillaries that are capable of dilation and constriction in order to help the body maintain its homeostasis. This system is also an example of negative feedback

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.

Cells membranes are a phospholipid bilayer, with the hydrophobic "tails" of the phospholipids oriented to the interior of the bilayer, and the hydrophilic "heads" to the exterior of the bilayer.

They are fluid, which means that other molecules in them, such as proteins, are not fixed in position. One of the components of the membrane in animal cells is cholesterol, which helps to give rigidity and strength to the membrane

The cell membrane is impermeable to ions and polar molecules, while hydrophobic molecules can pass by passive diffusion.

This means that only statement 2 is true (option b).

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,

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.

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.

The male and female reproductive parts in plants are different in terms that the female plants (pistiliate) possess a functional pistil but lack stamens, while the male plants (staminate) contains stamens, but no pistils. Therefore the complete flower structure have stigma, style, pistil, stamen and the other acessory parts of the reproductive system, while a imperfect (pistillate) flowers don't have a stamen. According to the question and the information above the correct alternative to differenciate the gender of that plant flower is A. stamen.

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.
