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

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,

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.

the chloroplasts of land plants are thought to have been derived according to evolutionary sequence:
cyanobacteria → green algae → land plants

A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.

This concept has had a fresh influence on the notion of Darwinian evolution and has been discovered to apply to the whole sequence. It is well demonstrated in the orderly copolymerization of amino acids. I'll go through a few issues with handling the teaching of contentious themes in this section.

If we took a linear piece of DNA and cut it with the restriction enzyme EcoRI which had three restriction sites for EcoRI, then the resulting number of fragments that it would produce is five (5) fragments in a linear sequence and four (4) fragments in a circular piece.

A restriction enzyme is a protein that has a defined catalytic activity that can be used to cut a given sequence of nucleic acids.

In this case, the EcoRI restriction enzyme can be used to cut in a specific nucleotide sequence that contains a given linear order of nucleotides in the cutting site.

Therefore, with this data, we can see that the restriction enzymes are able to cut the nucleic acids in specific sequences such as the EcoRI restriction enzyme that cut at particular nucleotide regions (this enzyme cuts at AATT positions).

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.

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.

Explanation:

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).

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.

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.
