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.

5. Consider two soil samples, one from a tropical rain forest and the other from a temperate
deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer
Answer:
Temperate deciduous forest
Explanation:
The temperate deciduous forest will have more organic matter concentration in it.
Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.
Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.What is the impact of genetically modified corn on individuals?

Most of the water vapor in the atmosphere comes from evaporation of water from oceans. Most of this evaporation occurs where there is the greatest solar radiation, which is - Group of answer choices around islands in the Pacific. along the coast of Europe. near the Equator.
Answer:
near the Equator
Explanation:
The part of the Earth that receives the most amount of solar radiation is always near the Equator. This is because the Earth itself revolves around the run in a tilted motion, since the Earth is round this makes the Equator always closest to the sun which means it will always get the most direct amount of Sun Radiation. This radiation causes more heat which ultimately causes a greater amount of water to be evaporated in this location.

PLZ HURRY
Answer:
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.
Explanation:
Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.
Answer:
See the answer below
Explanation:
From the illustration of the experiment, the question that Carson can best answer is that "Do bananas develop more brown spots if they are kept in bags with holes compared to bags without holes?"
The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.
Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes.
