Answer:
[tex]NH_{4} ^{+}, NO_{3} ^{-}, CO_{3} ^{2-}[/tex]
Explanation:
A molecule is a chemical species containing at least two chemically-bonded atoms while an ion is a charged chemical species.
Hence, a molecular ion must be a molecule and must carry a charge (positive or negative).
Given the two criteria above, then [tex]NH_{4} ^{+}, NO_{3} ^{-}, CO_{3} ^{2-}[/tex] are all molecular ions. [tex]NaCl[/tex], although a molecule, is not a molecular ion because it is not charged.
The following are simple molecular ions NH₄⁺, NO₃⁻, and CO₃²⁻. The correct options are a, c, and d.
What are molecular ions?Molecular ions are the name given to molecules and elements that are charged either positively or negatively. Many elements participate in chemical reactions and form bonds with each other's atoms. Those elements that have a charge on them are known as molecular ions.
These elements or compounds taking part in bond formation are called ions because when they donate or get electrons, they acquire a charge, positive or negative.
In the following, NH₄⁺, NaCl, NO₃⁻, and CO₃²⁻. All are simple molecules, but NaCl is not considered an ion because it does not contain any charge. So this will not be an ion.
Thus, the options are a. NH₄⁺, c. NO₃⁻, and d. CO₃²⁻.

What are humans doing to limit the release of acid rain? Thankyou x
Answer:
Not using fossil fuels and using renewable fuels instead.
Explanation:
Like using solar and wind power as renewable energy sources will reduce the release of acid rain as it doesn't produce as mush pollution.
Answer:
Explanation:
These gases are exerted into the sky as pollutants through human activities. Then, when the clouds form due to condensation, and become to heavy to hold, they start to release water in the form of rain. However, one slight change would be that they bring down the Sulphur dioxide and nitrogen dioxide with them.
This acid rain is mostly seen after a long summer, and when the first few rains are seen. This rain highly affects the happenings at the Earth. For example, they make the soil in fertile and leave farmers and gardeners under lots of work for when they re - plant later that year.
So, as you can see humans really have to try and stop acid rain or at least reduce it. So, they try to reduce human activities that release the acidic gases into the air in the first place. This is the only way they are able to reduce it. These human activities include burning of fossil fuels, etc.
Since reducing this means reducing luxuries, humans are able to find alternative methods to do this. Like instead of burning fuels, they can get it form solar power that is renewable
Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, "What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?" If molecules are small enough, then . . .
Answer:
They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
Answer:
Sample Hypothesis: If molecules are small enough, then they will diffuse across a semipermeable membrane because they can pass through its tiny openings.
-correct conclusion (“then”): Molecules will diffuse through the membrane
-correct reason (“because”): Molecules can pass through the membrane’s tiny openings.

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? osmosis passive transport active transport diffusion
Answer: Active Transport
Explanation: Active transport is the movement of a substance (proteins, enzymes, etc.) from one area of the cell membrane to the next during diffusion, so this would most be affected due to the kinds of substances being transported across the cell membrane and damage can have an impact.
Carrier proteins are involved in active transport. The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.
What are the carrier proteins?Carrier proteins are transmembrane molecules involved in active transport.
They carry molecules from one side of the membrane to the other side.
What is active transport?Active transport acts against the electrochemical gradient, so it does need the energy to transport substances.
It carries molecules from a low concentration side to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.
The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.

What is the next phase of the carbon cycle for the carbon source labeled C? (2 points) Label A shows a collection of coal, oil and gas. Label B shows a collection of trees and vegetation. Label C shows sky and open atmosphere. Cellular respiration Photosynthesis Fossil fuels DecompositionWhat is the next phase of the carbon cycle for the carbon source labeled B? Label A shows a collection of coal, oil and gas. Label B shows a collection of trees and vegetation. Label C shows sky and open atmosphere. Condensation Transpiration Photosynthesis Decomposition
Answer:
The first answer is "Cellular Respiration" and the second answer is "Photosynthesis".
Explanation:
If we start tracking the carbon in the cycle starting from the atmosphere, we can say that the order it goes through looks like this:
First it gets passed into the plants through photosynthesis.Then it passes to the other organisms that consume the plant or if the plan decomposes it gets passed onto the soil.Then as the organisms that consume the plants die, it finally gets passed to the soil and either helps other plants grow or turns into fossil fuels.For the first part, the next phase after open atmosphere for the carbon is going to be photosynthesis by the plants leaves.
For the second part, the next phase after trees and vegetation is going to be decomposition.
I hope this answer helps.
The labeled C and Labeled B in the given carbon cycle are:
1. cellular respiration
2. photosynthesis
1. The next phase of the carbon cycle for the carbon source labeled C:It will be photosynthesis, as this process is associated with trees and vegetation, in Label B.fossil fuels which is labeled under ADecomposition of organic matter will either take place on land or in water.CO2 released from respiration will add to the atmospherethus, the next phase: cellular respiration.

Which biomolecule do you think is most important in your diet? Why did you pick that biomolecule? Which biomolecule do you think is most important in cell function? Nutrition and snack foods A. List your three favorite snack foods. B Collect a nutrition label from each food. C. If any of the foods on your list don’t come in a package, you can look up the nutrition information on the Internet. D. Write a paragraph about each food. Is it a good source of carbohydrates, lipids, and protein? Would you consider this food healthy? Why or why not? 2. You may have heard the saying, “You are what you eat.” to explain what this statement means.
Answer/Explanation:
There is no single biomolecule that is most important in one's diet; however, proteins would be a fitting choice. This is because there are certain amino acids -- 9 in fact -- that our bodies cannot naturally produce and of which proteins consist. We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
A. Welch's, Oreos, Chips Ahoy
B. You should be able to do this.
C. Proves my point in B.
D. Yeah, generally the snacks I chose are not healthy, even Welch's fruit snacks. It's junk food and not high in protein. "You are what you eat" makes sense in the quite literal sense because your body mass, your health, and your overall physical attributes are determined by your diet, on top of exercise and your activities throughout your life.

How would driving from Boston (near sea level) to summit of Mt. Washington affect the rate of oxygen exchange in your lungs? Explain in 1-2 sentences plz
Answer:
The rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington
Explanation:
At near sea level, Boston, where there is sufficient dense air and plentiful supply of oxygen, the rate of breathing and oxygen exchange in the lungs is at normal levels
At the height of 6,288.2 feet, which is the height of the summit of Mt Washington, the lung does more work to extract the oxygen from the air present which is less dense and contains less oxygen than the air at sea level such that a larger volume of air is required to supply the amount of oxygen the body requires
Therefore, the rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington.
