The negative charge established along a nerve cell membrane is due to the D.higher permeability of K relative to Na.
Whilst the membrane will become permeable to k+, the k+ ions will freely waft until that membrane potential is reached. In this case, the ok+ ions will float OUT of the mobile, contributing to the mobile's hyperpolarization (from -70mV towards -96mV) within the path of the k+ equilibrium potential.
The bad charge inside the cellular is created via the cellular membrane being greater permeable to potassium ion movement than sodium ion movement. In neurons, potassium ions are maintained at excessive concentrations in the mobile whilst sodium ions are maintained at high concentrations out of doors of the cellular.

George is generally sensory challenged. B. Men have less sensitive olfactory receptors. C. Estrogen enhances olfaction. D. Betty has never smelled tuna. E. None of the above answers are correct.
If Females Can More Correctly Identify The Smells Of Certain Items, Then B. Men have less sensitive olfactory receptors.
A proper sense of smell depends on the olfactory bulb since it sends scent information from the nose to the brain.Compared to men, women have more cells in the olfactory bulb, the part of the brain responsible for smell perception.Women smell things better than males because they have more brain cells in the part of the brain responsible for smell. This area of the brain, also referred to as the "olfactory bulb," is in charge of receiving information about scents from the nose.Additionally, the olfactory bulbs of women have around 50% more neurons than those of men, proving that women have far stronger noses than men.learn more about olfactory receptors here: https://brainly.com/question/13153033

The whole blood with solutions of different concentrations mixed in order to find the tonicity of each solution.
Osmosis is the movement of water from the high solvent concentration to low solvent concentration. The solution on addition of the red blood cells becomes opaque and the cells can be observed under the microscope. If the solution is hypertonic, the red blood cell loses water and undergo shrinkage. If the solution is isotonic, the water flow will be at equal rates and the cell will remain intact. If the solution is hypotonic, the water will flow into the cell causing the cell to swell up.

The picture below shows a soil texture triangle.
Image of a soil texture triangle. Each side is labeled one of the three main soil types—silt, clay, and sand—and is divided into percentages, from 0 to 100. Each point in the triangle corresponds to a different soil texture, consisting of a different combination of silty, sandy, and clay soils. For instance, the top part of the triangle contains soils that range from approximately 50 percent clay to 100 percent clay. All these different soils are considered clays. Soils located farther down the triangle contain an increasingly small percentage of clay; for example, silty clay soils are primarily silt, with more clay than sand, and sandy clay soils are primarily sand, with more clay than silt. Soils located in the middle of the triangle contain roughly equal percentages of clay, sand, and silt; these soils are called “loam.” There are silty loam soils, which contain more silt than clay or sand; clay loam soils, which contain more clay than silt or sand, and sandy loam soils, which contain more sand than silt or clay. There are also silty clay loam soils and sandy clay loam soils.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. What is the frequency of individuals that are heterozygous for this allele
In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. The frequency of individuals that are heterozygous for this allele is 0.32.
Hardy Weinberg Equilibrium Principle A stable, idealized population's constant frequency of alleles and genotypes is described by the Hardy-Weinberg equilibrium principle. In a sizable population, random mating, or spontaneous mutations are necessary for Hardy-Weinberg equilibrium.The Hardy-Weinberg equation dictates that the sum of the allele frequencies for each allele at the locus must equal 1, therefore p + q = 1. The Hardy-Weinberg equation is also written as p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is that of the "a" allele.
The homozygous genotype AA frequency is represented by p2, the homozygous genotype aa frequency by q2, and the heterozygous genotype aa frequency by 2pq in the equation.
Here, q = 0.2. Because of this, p = '1- q = 1 - 0.2 = 0.8.
The population of individuals who are heterozygous will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.
Hence, This indicates that the population is heterozygous with a frequency of 0.32.
