[tex]NH_ 3[/tex]. [tex]NH_3[/tex] has a polar covalent bond, which means it has an uneven distribution of electrons, making it more soluble in water, which is also a polar molecule.
What is Bond polarity?
Bond polarity is the measure of the degree to which the electrons in a bond are attracted to one atom or the other. A polar bond is an unequal sharing of electrons between two atoms, while a non-polar bond is a more equal sharing. Polar bonds have a positive and negative charge, while non-polar bonds do not.
What are Electrons?
Electrons are particles that have a negative electrical charge. They are the main subatomic particles that make up atoms and are located in the electron cloud surrounding the nucleus. Electrons are responsible for chemical bonds between atoms and are involved in the transfer of energy.

a. small change in resting membrane potential confined to a small area
b. charge difference across the plasma membrane when the cell is in an unstimulated state
c. larger change in resting membrane potential that spreads over the entire surface of a cell
d. membrane becomes more positive when Na+ diffuses into cell
e. return to resting membrane potential
Option d Depolarization membrane become more Depolarization positive when Na+ diffuses into cell.
Because sodium is a positively charged ion, it will cause a change in the relative voltage between inside and outside the cell. Because the resting potential is the membrane's state at a voltage of 70 mV, sodium cation entering the cell causes it to become less negative. Neurotransmitters that open Na+ channels tend to make the Depolarization membrane potential more positive, while those that activate K+ channels tend to make it more negative; those that inhibit these channels tend to have the opposite effect.

gray seed color in peas is dominant to white. assume that mendel conducted a series of experiments where plants with gray seeds were crossed among themselves, and the following progeny were produced: 302 gray and 98 white. (a) what is the most probable genotype of each parent? (b) based on your answer in (a) above, what genotypic and phenotypic ratios are expected in the progeny? (assume the following symbols: g
The theory of genetics, first proposed by Gregor Mendel in the 19th century, states that certain characteristics in plants and animals are determined by the combination of two alleles, one from each parent.
In his experiments with peas, Mendel discovered that the gray seed color was dominant to the white color. This means that when two plants with different alleles for the seed color trait were crossed, the resulting offspring would typically have the characteristic of the dominant allele.
(a) The most probable genotype of each parent is GG and Gg. This is because the parent plants with gray seeds are homozygous dominant (GG) and heterozygous (Gg).
(b) If the two parent plants are GG and Gg, the expected genotypic ratio in the progeny will be 1 GG: 2 Gg: 1 ww. The expected phenotypic ratio will be 3 gray: 1 white. This is because the dominant gray allele (G) is more likely to be expressed in the progeny than the recessive white allele (w). Therefore, the progeny of this cross will have a higher proportion of gray seeds than white seeds.

What are parallel pathways?
There are three pathways within V1 that perform different functions in parallel.
Magnocellular pathway: begins with m type ganglion cells of the retina. These cells send axons to the magnocellular layers of the LGN. These layers project to layer IVCa of striate cortex, which in turn projects to layer IVB. Because of cortical neurons are direction selective this pathway may be involved in the analysis of object motion and the guidance of motor actions
The parvo-interblob pathway: originates with p-type ganglion cells f the retina, which project to the parvocellular layers of the LGN.The parvocellular LGN sends axons to layer IVCa of striate cortex which projects to layer II and III inter blob regions. Neurons in this pathway have small orientations-selective receptive fields, so perhaps they are involved in the analysis of fine object shape.
The Blob pathway: receives input from the subset of ganglion cells that are neither m or p type cells. These non m/p cells project to the koniocellular layers of the LGN. The koniocellular LGN projects directly to the cytochrome oxidase blobs in layers II and III. Many neurons in the blobs are color selective so they might be involved in analysis of color.
Answer:
The term "parallel pathways" refers to the fact that there are multiple neural pathways in the brain that perform different functions, and that these pathways operate in parallel with each other. In the context of vision, the three main parallel pathways are the magnocellular pathway, the parvocellular pathway, and the Blob pathway. Each of these pathways originates in different cells in the retina and performs different functions in the visual system. For example, the magnocellular pathway is involved in motion detection and the guidance of motor actions, while the parvocellular pathway is involved in the analysis of fine object shapes. The Blob pathway is involved in color analysis. Together, these three pathways work in parallel to enable the brain to process visual information.

Male gametes, or spermatozoa, are the first to develop into gametes. The main hormone involved in male sex, testosterone, is also produced.
The spermatic cord holds the testes, which are oval organs in the scrotum that are about the size of extremely big olives, at either end. Males often have two testicles. Sperm and testosterone, the main hormone involved in male sex, are both produced in the testes. Seminiferous tubules, coiling collections of tubes, are found inside the testes. Through a process known as spermatogenesis, these tubules are in charge of creating the sperm cells.

What type impulses m(sensory or motor) travel on dorsal root?
Answer:
The sensory impulses generated in the periphery (pain, touch, temperature changes) activate the peripheral processes of the spinal ganglion neurons. These impulses then travel to the spinal cord either directly (bypassing the cell bodies) or through the neuronal cell body in the dorsal root ganglion.
Explanation:
The dorsal root transmits sensory information, forming the afferent sensory root of a spinal nerve. The dorsal root of the spinal nerve mediates the movement of motor impulses to go out of the spinal cord
Dorsal Roots: convey mainly “afferent” sensory information into the dorsal spinal cord. (Blumenfeld, 22) Also referred to as 'dorsal nerve roots. ' Ventral Roots: carry mainly “efferent” “motor” and “signals” from the ventral spinal cord to the periphery.
