Which city is located at 60s and 0
Groundwater is found in pores of soil and rock,
O True
O False
Answer:
true
Explanation:
In order to maintain homeostasis, the human body must be able to get rid of the waste products produced by cellular processes. The kidneys, for example, are responsible for removing waste from the bloodstream by producing urine. Urine produced in the kidneys then travels through the ureter and into bladder, and is finally expelled from the body by the urethra. The kidneys, ureter, bladder, and urethra help the body maintain homeostasis through the process of what?

What direction will solutes move if a protein pump is functioning properly?
Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane.
Explanation:
After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.
Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
____allows some things to enter and leave cells, while keeping other things in the cell or keep other
things out of the cell.
A:fermentation
B:A selectively permeable membrane
C:metabolism
D:osmosis
Answer:
The cell membrane is the outer layer of the cell. The primary function of the cell membrane is to regulate what substances enter and leave the cell. The cell membrane is selectively permeable, or "semi-permeable", meaning that the membrane only allows certain substances to enter or leave the cel
Answer:
b
Explanation:
because the membrane of a cell is responsible for what enters n leave the cells.
it can't be "D" because osmosis is the process by which water molecules enter a permiable or semi permiable membrane of an object from an area of high concentration to an area of low concentration.
fermentation is the process by which chemical changes occur in an organic matter do the answer is definitely not A
metabolism is the chemical processes that occur in an organism to maintain its life so the answer is not c
True or False
Osmosis is the movement of water into and out of a cell.
Answer:
True
Explanation:
True
Osmosis is a special kind of diffusion that only involves water moving through a selectively permeable membrane.

Pick a topic.
Research.
Hypothesis.
Experiment.
Construct an exhibit for results.
Write a report.
Practice presenting.
Pick something you are interested in, something you'd like to think about and know more about
Then do some background research on the topic.
Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.
Design and carry out your research, keeping careful records of everything you do or see and your results or observations.
Construct an exhibit or display to show and explain to others what you hoped to test.
Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.
Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

Which area of Earth is most similar to the sun’s convection zone?
Answer:
The Mantle
I hope this helps
The mantle is the part which is the most similar to the sun’s convection zone. It is the second layer of Earth.
Which layer from Earth's atmosphere is convective in nature ?It is the troposphere that is convective in nature. Troposphere means the region of mixing.
The mantle is the most similar to sun's convection zone. Sun's convection zone is later dominated by the convection currents that carries energy outward to surface. Mantle is second layer of Earth.
The zone is not that dense enough to just use the radiative transfer of the energy, infact , they uses the thermal convection zones in just other words then it boils. Energy is then carried out through the thermal columns to surface of sun and later creates out areas that are seen as the solar granulation and the super granulation.

Biomolecules are quite necessary for the perpetuation of life processes.
Living organisms are composed of diverse substances of biological importance called biomolecules.
Many biomolecules contain carbon, hydrogen and oxygen.
Nitrogen is very important in making amino acids because amino acids must contain nitrogen.
Cholesterol is found in the cell membrane. It is very important in building the cell membrane as well as the formation of several hormones.
