(P high - P low) is re-established to optimize the variable(s) of Fick's law.
According to Fick's law of diffusion, particles subject to random thermal motion have a tendency to move from an area of higher concentration to an area of lower concentration. Fick's diffusion law, which asserts that the diffusion flow is proportional to the concentration gradient, mathematically describes three-dimensional diffusion.
The diffusion process is explained by Fick's law of diffusion (movement of molecules from higher concentration to lower concentration region). Adolf Fick first explained Fick's Law of Diffusion in 1855. Normal diffusion, often known as Fickian diffusion, is a diffusion process that complies with Fick's rules. An abnormal diffusion process also referred to as non-Fickian diffusion, defies Fick's rules.
According to Fick’s law of diffusion,
“The molar flux due to diffusion is proportional to the concentration gradient”.

Answer:
The large differences observed in genomic size among eukaryotes correspond primarily to differences in the amount of noncoding DNA
Explanation:
The whole collection of DNA and genetic information found in a given organism or cell makes up that organism's genome. For the majority of the time, when we think of genes, we consider those that produce proteins or those that are translated to mRNAs and then converted into proteins. But, genomes include much more than simply those that produce proteins. There is big difference in size and content of prokaryotic and eukaryotes. One mRNA generates one protein inside a eukaryotic gene in some kind of a biochemical or signaling pathway; operon organization is not present. A eukaryotic gene's numerous exons can really be cleaved in various ways to produce several mRNAs & proteins from just a single gene.

Relationships between organisms and their physical surroundings as well as forces inside the biotic community have the potential to change the environment. The maximum number of creatures that a region can sustainably support is known as an ecosystem's carrying capacity. When a population is dense, the habitat may undergo such significant changes that the ecosystem is no longer suited for the survival of that species. For instance, excessive grazing on a piece of land may prevent it from supporting the grazing of the animals inhabited there.
Predators were eliminated and the forest service outlawed hunting.According to the graph, by 1924, the population had gotten out of hand; 100,000 people were living on a plateau with a carrying capacity of 30,000.Because the deer destroyed their habitat, there were 100,000 deer where there should have only been 30,000, which caused the population to fall.Due to natural predators and legal hunting, the deer population was much below its carrying capacity.The deer were unable to survive on the range after hunting was once more permitted.

Sweet potatoes Ipomoea batatas are hexaploid with 90 chromosomes. (6n = 90).Then they will have 360 telomeres in the G1 phase of the cell.
Chromosomes are the compact form of genetic material. It consists of proteins and DNA that are wound together to form this compact structure. A chromosome consists of two sister chromatids that are joined together by a protein called kinetochore and the point of junction is called the centromere. Each sister chromatid has 2 telomeres and therefore, one chromosome has total 4 chromosomes.
G1 phase of the cell cycle is the one where the cell prepares for the nuclear formation. It synthesizes various mRNA and proteins that are required in the S phase of the cell cycle. There is no change in the number of chromosomes during this phase and hence the number of telomeres will remain 360.

Infancy is a sensitive period in terms of brain development especially due to its ability to adapt and learn from experiences.
Sensitive periods are the period in which an individual is more sensitive to various experiences and environments. He learns from his experiences and makes himself adapt to the environment. It occurs during prenatal and postnatal periods when development generally occurs slower. For example, a child learns his native language slowly while living in an environment and learns more experiences.
Sensitive periods in terms of brain development are when synapses and their neural routes are created earlier than other times. The formation of synapses and neural pathways is termed synaptogenesis. During this period, the brain prepares itself to learn from experiences and adapt itself to the environment.
