Options:

A. As a consequence of climate change, robins in the northeastern United States sing earlier in the spring than they did two decades ago.

B. As a consequence of legislation promoting cleaner air, the frequency of black peppered moths in Europe has decreased in the last half-century.

C. Due to a genetic bottleneck, the frequency of one allele has increased in a population of Drosophila subobscura.

D. After repeated exposure to high temperatures, an individual turtle can tolerate heating more successfully.

The conclusion that can be drawn by observing the cross between plants with purple flowers, long pollen grain plants and plants with white flowers, round pollen grains is that: (D) The traits are probably linked.

Cross is the breeding between two organisms that may or may not be of the same species. This results in an offspring that possesses the traits from both the parents. The offspring may show traits similar to one or both the parents or their traits may be completely different.

Linkage is the phenomenon where the two genes are placed closely together in a chromosome such that their segregation usually happens along with each other. If the offspring produced by a cross yields are more similar to their parents then their genes can be said to be linked.

Greenhouse effect is caused by atmosphere reflecting longwave radiation emitted by the earth back down to earth's surface is : true.

Greenhouse effect is actually caused by the atmosphere trapping some of the energy from sun that is absorbed by Earth's surface. This trapped energy, in the form of heat, warms the atmosphere and also Earth's surface.

Earth's surface absorbs the shortwave radiation of sun and re-emits some of this energy as longwave radiation. Certain atmospheric gases, like carbon dioxide, methane, and water vapor, absorb this longwave radiation and re-emit some of it back towards Earth's surface. This causes  Earth's surface and lowers atmosphere to warm, similar to the way greenhouse traps heat to grow plants.

When the child's biological parents offer a nurturing environment, there are passive genotype-environment connections. Genetic and environmental relationships exist because a child's traits lead to particular surroundings.

The link between a kid's genotype, which he or she receives from both parents, with the environment in that the child is raised is known as passive genotype-environment correlation. The social environment's response to individuals based on their inherited traits is referred to as evocative genotype-environment correlation. One's disposition, such as whether they are more outgoing or introverted, will influence how others regard them.

The molecule in birds which has a similar effect to 2,3-bisphosphoglycerate (2,3-BPG) on the oxygen binding to hemoglobin in birds is inositol hexaphosphate (also known as phytic acid).

Like 2,3-BPG, inositol hexaphosphate binds to a site on the hemoglobin molecule and reduces its affinity for oxygen, which can enhance the delivery of oxygen to tissues with high metabolic demand, such as in birds during flight.

Inositol pentaphosphate, inositol tetraphosphate, and inositol triphosphate are also inositol phosphates, but they do not have that much significant effect on the oxygen binding to hemoglobin in the same way as 2,3-BPG and inositol hexaphosphate.

2,3-bisphosphoglycerate (2,3-BPG), also known as 2,3-diphosphoglycerate (2,3-DPG), is a small molecule that plays an important role in the regulation of oxygen transport in the body.

In red blood cells, 2,3-BPG binds to hemoglobin and reduces its affinity for oxygen, which allows oxygen to be more readily released to tissues in need. This is particularly important in tissues with low oxygen levels, such as during exercise or at high altitudes.

A sensitive activator of ADH secretion is plasma osmolality. Hence option 'd' is correct.

Osmolarity of the plasma the blood plasma's osmolarity, which measures the level of hydration. During periods of dehydration and rehydration, variations in hydration status have an impact on the plasma osmolarity. The osmolarity of normal plasma is between 280 and 300 mOs/kg. From lab to lab, this could change a little.

When you are dehydrated, your blood's osmolality rises, and when there is too much fluid within your system, it falls. Osmolality is managed in a special way by your body.

The difference in general transcription factors between parietal cells and other cells is evidence that gene regulation results in differential gene expression and influences cellular products.

As per the question given,  

The claim that gene regulation results in differential gene expression and influences cellular products is best supported by the statement that parietal cells and other cells possess different general transcription factors. Transcription factors are proteins that bind to specific DNA sequences to regulate the transcription of genes. General transcription factors are required for transcription initiation by RNA polymerase in all eukaryotes.

However, different cell types can have different levels of general transcription factors and other transcription factors, leading to differential gene expression and the production of different cellular products. In the case of parietal cells, they possess specific transcription factors that allow them to produce and secrete hydrochloric acid, which is not produced by other cells.

In his experiment, Thomas Hunt Morgan crossed a red-eyed female fruit fly (Drosophila melanogaster) with a white-eyed male. gene affecting eye color was on the X chromosome was the inheritance pattern of eye color in the F1 generation.

define chromosomes ?

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Thomas Hunt Morgan crossed a red-eyed female fruit fly (Drosophila melanogaster) with a white-eyed male. The observation that allowed Morgan to conclude that the gene affecting eye color was on the X chromosome was the inheritance pattern of eye color in the F1 generation.

The female fly has two X chromosomes, while the male fly has one X chromosome and one Y chromosome. In Drosophila, the gene for eye color is located on the X chromosome. The X-linked allele for red eyes is dominant, and the X-linked allele for white eyes is recessive.

When Morgan crossed the red-eyed female with the white-eyed male, all of the F1 progeny had red eyes. This result is consistent with the dominant inheritance of the red-eyed allele. However, when Morgan crossed the F1 progeny with each other, he observed a different pattern. Among the F2 generation, Morgan observed a 3:1 ratio of red-eyed to white-eyed flies, which is the expected ratio for a Mendelian trait controlled by a single gene.

Importantly, all of the white-eyed flies in the F2 generation were males, and none of the females had white eyes. This observation led Morgan to conclude that the gene for eye color was located on the X chromosome, since males only inherit one X chromosome and therefore only have one copy of the gene. The lack of white-eyed females in the F2 generation is consistent with the recessive nature of the white-eyed allele and the fact that females have two X chromosomes.

Hemophilia is a genetic disorder which is an X-chromosomal recessive disorder.

Hemophilia is a recessive genetic disorder in which the blood does not clot in the typical way because it does not have enough amount of blood-clotting proteins called as clotting factors.

The abnormal gene which is responsible for hemophilia is carried on the X chromosome. Males have only one X chromosome and one Y chromosome.

Template genomic DNA is not a component of a PCR reaction.

Polymerase chain reaction is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.

The majority of PCR methods rely on thermal cycling. Thermal cycling exposes reactants to repeated cycles of heating and cooling to permit different temperature-dependent reactions—specifically, DNA melting and enzyme-driven DNA replication.

PCR is based on three simple steps required for any DNA synthesis reaction: (1) denaturation of the template into single strands; (2) annealing of primers to each original strand for new strand synthesis; and (3) extension of the new DNA strands from the primers.
