Roads are sometimes salted in the winter to prevent ice build up. When the ice and snow melt, the water can also carry salt off
valkas [14]

Answer:

See the answer below

Explanation:

<em>When the salt water resulting from using salt to thaw ice and snow is washed off the road, the nearby plants along the roadside would be subjected to osmotic stress due to the lower water potential of the soil water when compared to that of their cells. Consequently, the plants are expected to lose water to the surrounding salt solution until an equilibrium is established between their cytosols and the soil solution. </em>

Which molecule will undergo only london dispersion forces when interacting with other molecules of the same kind?.
chubhunter [2.5K]

Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.

London dispersion force:

  • The weakest intermolecular force is called the London dispersion force.
  • When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
  • There are instances when this force is referred to as an induced dipole-induced dipole attraction.

     Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.

<u><em>Butane:</em></u>

  • It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.

What would most likely happen if the parietal cells in your stomach stopped functioning?
salantis [7]

If the parietal cells in your stomach stop functioning The pH of the abdomen will rise.

Parietal cells, called oxyntic cells, are stomach epithelial cells that release intrinsic factors and hydrochloric acid (HCl). These cells are present in the stomach's gastric glands, which are situated in the fundus and body regions. Gastric acid secretion, which helps with food digestion, mineral absorption, and bacterial control, is controlled by parietal cells.

In the center of the glands in the fundus-body region of the stomach are the parietal cells. They release the intrinsic factor, a protein that binds vitamin B12, and gastric acid, or hydrochloric acid (about 0.16 M, pH 0.8). The parietal cells that are destroyed are unable to create enough stomach acid. As a result, the pH of the stomach rises, food digestion is hampered, and the risk of gastroenteritis increases.

Where is DNA found? A. vacuole B. chromosomes C. cell membranes D. Golgi body
dmitriy555 [2]
<span>in eukaryote cells DNA is found in the nucleus of the cell, the form the DNA (e.g. chromosomes vs. chromatin) is in depends on what stage of the cell cycle you are talking about. In cells that have mitochondria, DNA is found there as well. Mitochondrial DNA is distinct from nuclear DNA and doesn't code for the same things. In prokaryotic cells DNA is found in the cytoplasm. Don't forget that other entities may also contain DNA such as viruses.

Although DNA is technically confined to the places outlined above, the reality is cells are dying all the time and spilling their contents including their DNA. As a result DNA is all over us and everything we touch, and the same goes for other organisms.

Bacterial cells DON'T typically have a nucleus. They are called prokaryotic because of that (prokaryotic means "before nucleus" where as eukaryotic means "true nucleus"). Their DNA is typically in the cytoplasm usually as a single circular shaped chromosome. The also sometimes have smaller peices of circular DNA called plasmids that are also in their cytoplasm which they can exchange with each other.. </span>
