Answer:
Population Growth: Exponential

IF there were a membrane separating two solutions one with 80% solute and the other with 20% solute, in which direction through the membrane will water move to?
toward the 20% solute side of the membrane
toward the 80% solute side of the membrane
Answer:
toward the 20% solute side of the membrane
Explanation:
that is the process of osmosis, in which the water moves in the direction that tends to equalize the solute concentrations on the two sides.
Basically it's to make it 50% 50%, so the water moves to the 20% solute side to raise the %

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Answer:
Hope the below helps!
Explanation:
Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.
Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.
I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
Answer:
This is due to the Greenhouse Effect.
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
Why do greenhouse gases absorb heat?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat. They radiate the heat back to the Earth's surface, to another greenhouse gas molecule, or out to space. Here are several different types of greenhouse gases. The major ones are carbon dioxide, water vapor, methane, and nitrous oxide. These gas molecules all are made of three or more atoms compared to oxygen which only has 2 atoms. I hope this helps you.

Which of these is NOT a source of energy in
chemosynthesis?
A. ammonia
B. sulfide
C. methane
D. sunlight
Chemosynthesis is the production of energy from biological and chemical means. Sunlight is not the source of the energy in chemosynthesis. Thus, option D is correct.
What is chemosynthesis?Chemosynthesis is the process by which the living cells make organic compounds and other energy-producing compounds by the involvement of inorganic reactions.
The process of chemosynthesis does not require sunlight, unlike the photosynthesis that has been producing energy through it. The microorganism usually uses this process to make food like glucose to drive the metabolic reactions.
The chemosynthesis reaction uses ammonia, sulfide, methane, etc. to produce organic compounds that provide the energy needed by the cell.
Therefore, sunlight is not needed in chemosynthesis.

Answer:
hi hi !
you are a protist, paramecium
Explanation:
have a great day!
The organism which lives in pond water with cilia covered body who eat bacteria by endocytosis is paramecium.
What is paramecium?A genus of eukaryotic, unicellular ciliates known as Paramecium is a representative of the ciliate group. In stagnant basins and ponds, paramecia can be found widely in freshwater, brackish, and marine settings.
Biological processes of paramecium is frequency studying because they are easily cultivated and can be made to reproduce through conjugation and division.
The whipping movements of the cilia, which are placed in closely spaced rows along the outside of the body, are making paramecium propels itself.
Paramecia eat bacteria, algae, and yeast as food. The Paramecium uses its cilia to transfer prey creatures and some water into the cell through the oral groove where they are then consumed.
