Explanation:

There are basically three major classes of membrane lipid molecules, which are: phospholipids, cholesterol, and glycolipids.

What is cellular membrane?

The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.

The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

Lipids (phospholipids and cholesterol), proteins, and carbohydrate groups attached to some of the lipids and proteins are the primary components of the plasma membrane.

Membrane lipid molecules are classified into three types: phospholipids, cholesterol, and glycolipids.

Glycerol is a three-carbon molecule that serves as the membrane lipids' backbone.

Thus, these are the three molecular components of cell membranes.

Describe the genetic components of the genetic material containing two variants of each chromosome pair, one from each parent. Give an example of the inputs and outputs of mitosis.

Answers

Answer:

Human cells contain two sets of chromosomes, one set inherited from each parent. Each cell normally contains 23 pairs of chromosomes, which consist of 22 autosomes (numbered 1 through 22) and one pair of sex chromosomes (XX or XY). However, sperm and ova normally contain half as much genetic material: only one copy of each chromosome. Each chromosome contains many genes, the basic physical and functional units of heredity.

What are cell organelles ?

 

Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.

Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.

Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria  generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

Put the components of the visual projection pathway in order starting with the retina and ending with the brain. In order, starting from the lowest to the highest, we have:

Bipolar and ganglion cells of the retina Hemidecussation in optic chiasmOptic tracts Lateral geniculate nucleus (LGN) of the thalamusOptics RadiationPrimary visual cortex in the occipital lobe

The visual projection pathway is referred to as the channel through which electrical impulses created by the retina are transmitted to the brain.

When light penetrates the eye into the retina;

The bipolar and ganglion cells carry the signals from photoreceptors  (cones and rods) to ganglion cells, either actively or passively.

The axons of the ganglion gather and unite to form the optic nerve.

The optic nerve leads to the optical chiasm where hemidecussation of the optic nerve fiber takes place.

In the Optic Chiasm, the optic tract contains the nasal fibers that join from the left eye and connect with temporal fibers from the right eye, vice versa.

The lateral geniculate nucleus (LGN) which connects from the optic tracts has nerve endings that send optical radiation information from the superior visual fields to the inferior visual fields.

The primary visual cortex region is largely located on the occipital lobe of the medial brain surface, its function is to receive and process the optical radiation information sent from the (LGN).

Therefore, we can conclude that we understood the order, mechanism, and process in the visual projection pathway.

The negative membrane potential in a resting neuron is primarily due to :___________

a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.

Answers

Answer:

c

Explanation:

When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.

What is the membrane potential in a resting neuron?

It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.

Characteristics of a resting neuron

The resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.

When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.

Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.
