Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?
A. A procedure that uses the skins of potato left overnight in oil
B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight
D.A procedure that uses a banana that has been left overnight in milk
Answer:
B
Explanation:
The second option correctly shows the process of cellular osmosis.
When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

Explanation:
Baby cheeks are so sweet, pudgy, and pinchable. Pair those with adorable dimples and giggles and you have a baby akin to a kewpie doll.
Dimples are often seen as a desirable characteristic because they light up a face, even through smudged, terrible-two tears. They definitely seem to provide a little more personality!
But how do you know if your baby will have dimples? It’s a question that many soon-to-be parents ask themselves. The answer lies within miniscule, curly things called genes.

How does water behave when it freezes?
Answer:
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.

Fastttttttttttttttttttttttttttt I will give branliest
Answer:
ok
Explanation:
Answer:
A. Both of them are correct
Explanation:
Mechanical waves include the movement of water, from ripples in a puddle to giant rolling waves on the surface of the open ocean. For example, water waves (mechanical waves) can transfer energy across an entire ocean basin, even though individual water molecules do not travel great distances.
Electromagnetic propagation through water is very different from propagation through the air because of water's high permittivity and electrical conductivity. Plane-wave attenuation is high compared to air and increases rapidly with frequency.

O water droplets sticking to a window
O water forming a large drop
O water evaporating from a leaf

Answer:
The answer is Water droplets sticking to a window.
One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:
(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+
(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-
(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-
(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-
(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.
I'm not sure if it is C or D
Answer:
The answer is "Option C".
Explanation:
In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.
The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.What is deoxyribose?

A mineral forms in water heated by magma inside Earth. Which statement best describes this mineral? The mineral formed through evaporation. The mineral crystallized from molten material. The mineral formed when a hot water solution cooled. The mineral likely has all the same properties as the surrounding rock.
Answer:
The mineral formed when a hot water solution cooled.
Explanation:
The mineral is formed from hot water solution heated by magma in the Earth when the water is cooled because when hot water solution is heated by magma in the Earth, it begin to cool underground, then the elements and compounds present there move out of the water solution , after these, these elements and compounds then undergo crystallisation and form minerals . Pure metals that crysralise from hot water solution is called Veins.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.
What is a cell membrane made of?The cell membrane, also known as the plasma membrane, is uncovered 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.
These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.
As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.
Thus, the correct option is A.
