Answer: The given statement is True.
Nuclear DNA is present in the nucleus of eukaryotic cells. When working with the DNA samples, the best source of nuclear DNA is hair root that anchors the whole shaft of hair. Hair root possesses cells that are called as keratinocytes. These cells are ideal for the extraction of nuclear DNA.
But, DNA is not always available in a hair sample as it can not be extracted from shaft of hair ( since it undergoes cornification that destroys the genetic material of the cells).
Thus, given statement is True.
S phase
G2 phase
Answer: Image result for In which stage of the cell cycle is the cell preparing for division? *
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Hemoglobin is a crucial component of the circulatory system. It is a protein found in red blood cells that plays a central role in oxygen transportation. Therefore, the correct option is option 2.
The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood. Its primary function is to deliver oxygen, nutrients, hormones, and other essential substances to the body's tissues and organs.
In the context of the circulatory system, hemoglobin binds to oxygen in the lungs and carries it to the body's tissues, where it is released for cellular respiration. Additionally, hemoglobin helps transport carbon dioxide, a waste product of cellular metabolism, from the tissues back to the lungs, where it can be exhaled.
Therefore, hemoglobin's function and presence in red blood cells are closely associated with the circulatory system. Its role in facilitating oxygen and carbon dioxide exchange ensures the proper functioning and survival of cells and organs throughout the body.
Thus, the ideal selection is option 2.

Answer:
x=7
Explanation:
11=2x-3
Simplify it
14=2x
Divide each side by 2
x=7
Answer:I'm not sure the answer but I'm pretty sure if you divide 11 by 2x-3 you'll get the answer which a calculator can provide :)
Explanation:I think this is how you do it been a while since I had to do that kind of stuff
A molecule is a fundamental concept in chemistry that represents the smallest unit of a chemical compound that retains the properties of that compound. It's formed when two or more atoms come together and bond with each other.
Atoms are the basic building blocks of matter. They consist of a nucleus composed of protons and neutrons, surrounded by a cloud of electrons. Atoms can combine with each other through chemical bonds to form molecules. One of the most common types of chemical bonds is the covalent bond. In a covalent bond, atoms share electrons to achieve a more stable electron configuration.
In ionic bonding, atoms transfer electrons to each other, resulting in the formation of ions with opposite charges. These ions are attracted to each other, creating an ionic bond. The arrangement of atoms within a molecule is crucial to its properties and behavior. The type and arrangement of bonds determine the molecule's shape and how it interacts with other molecules.

Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.

Answer:
Inbreeding and greater chance of passing deletereous mutations through generations
Explanation:
There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding , that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.
On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.
The small population is prone to the disease more than the large population as the former have less diversity of organism and therefore there are fewer chances of occurrence of an organism that have resistance to the disease.
Further Explanation:
Genetic drift refers to the change in the allele frequency observed in the population due to random sampling. This may occur due to a bottleneck effect or Founder’s effect.
The allele frequency remains constant if the population follows the Hardy-Weinberg equilibrium.
There is more probability of occurrence of diversity in a population of large size that is the large population has an organism that has homozygous dominant allele, heterozygous allele, and homozygous recessive allele. So there is more probability that this population may have an organism having disease-resistant allele than the population of small size.
