Explanation:

C. A cut in skin heals

This process involves wound healing and tissue regeneration of somatic cells via mitosis.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells.

This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained. This process occurs regularly in somatic cells for growth, or to repair damaged tissue.

Answer: the answer is "A cut in skin heals

Explanation: This is because when cells divide they produce new cells which replace the ones which were on the place if the cut.

Answer:

Both are correct

Explanation:

The modern system classifies organisms into eight levels: domain, kingdom, phylum, class, order, family, genus, and species. The scientific name given to an organism is based on binomial nomenclature.

The "traditional" system relies on Linnean classification (what looks similar between the the two species.

<h2>Answer is option "A"</h2>

Explanation:

Oils and fats, which in science are called lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side. While the hydrophilic sides of a lipid will associate with the water in a solution, the hydrophobic sides of the lipid all cluster together to 'hide' from the water. Lipids therefore cluster together and form spheres where the hydrophobic sides are in the center away from the water while the hydrophilic sides are on the outside, associating with the water.
The ability of the atoms within a group to form hydrogen bonds with the water molecules around them makes them hydrophilic. Oxygen and nitrogen atoms readily form hydrogen bonds with water molecules, so any organic molecules that have oxygen or nitrogen atoms bound to their carbon skeletons will be hydrophilic.
For example, if we take the molecule for cholesterol, we see the OH group on the left is hydrophilic and will form hydrogen bonds with water, while the ring structures, which only consist of hydrogen and carbon atoms, are hydrophobic and will not associate with the water.
There are many different kinds of lipids with different functions. Lets start by examining phospholipids, which compose the cell membranes of animals. They form lipid bilayers, with one set of hydrophilic heads facing the exterior of the cell membrane and the other set facing the interior (as you can see on the diagram on screen). The hydrophobic portions of the lipid bilayer - the lipid tails - face towards one another, which allows them to hide away from the water inside and outside of the cell.
So,the right answer is option A "amphipathic molecules".

The substance used to separate the proteins from the dna

Genrish500 [490]

DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.

<h3>What is centrifugation?</h3>

Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.

It is the frequently applied techniques in the molecular biology laboratory.

The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.

Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
