Predict whether each substance will dissolve in water. dissolves in water, does not dissolve in water
Answer: for HCO it dissolves in water
for CH2OH IT dissolves in water
Explanation:
i just took the test
It depends on the particular substance concerned that one can predict whether it will dissolve in water or not. Listed below are some general principles:
Things that usually dissolve in water include:
1. Ionic Compounds: Many salts, including sodium chloride (table salt), dissolve in water because of the attraction between positive and negative ions and polar water molecules.
2. Polar Compounds: Due to the similar polarity of water molecules, substances with polar molecules, such as sugar and ethanol, tend to dissolve in water.
3. Many gases Some gases, such as oxygen (O2) and carbon dioxide (CO2), can partially dissolve in water.
Things that usually don't dissolve in water include:
1. Oils, greases, and hydrocarbons are examples of non-polar substances that do not dissolve in water because water is a polar solvent and does not interact significantly with non-polar substances.
2. Insoluble salts: Some salts, such as lead(II) sulfide (PbS) and silver chloride (AgCl), have low solubility in water.

xplain how organisms in lakes are related through the flow of energy. in environmental science
Answer:
Energy enters a community when plants and algae trap light energy during photosynthesis. They change the light energy into chemical energy in glucose, which then moves through the community as different organisms eat each other. Some energy is stored through fossilisation, while most of it is lost through heat dissipating into the environment.
Explanation:
Answer:Sample Response
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

What can be deduced about an igneous rock that is made up of very tiny crystals?
1.It formed in magma that cooled very slowly.
2.It formed from lava that cooled relatively quickly.
3.It formed from sediments in an ocean or lake floor.
4.None of these choices are correct.
Explanation: Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. In nature, crystals can form when liquid rock, called magma, cools.
Answer : It formed in magma that cooled very slowly.
How would our lives be different if water could not dissolve most substances?
Answer:
If water didn't dissolve most of the substances, humans, as water organisms, with the substances dissolved in the blood and other liquids wouldn't exist.
Explanation:
If water didn't dissolve substances, physical forces, connections between oxygen and hydrogen wouldn't be the same, so it means that the structure of the solid substances in the universe would be completely different. The law of physics would be different, and the whole universal system, as well.

Explanation:
Explain why worms have outer skin as their respiratory surface rather then lungs. NO google answer. ASAP
The simple answer for that will be that they are not complex organisms. Earthworms are simple organism with the small body,
So as there body is not that big thus they don't need any specialized organ system for the process of respiration. Every organism has the complex systems according to fulfill their needs, and most certainly the skin is very convenient medium for the respiration by the diffusion process.
-------------------------------------------------------------------------------------------------------------
BLOOD CIRCULATORY SYSTEM:They have a specialized system where it was needed, THE BLOOD CIRCULATION SYSTEM, There body is small but long and need blood to transfer the oxygen to each part of the body. There blood have the haemoglobin(it carries the oxygen), thus it is red just like us.
--------------------------------------------------------------------------------------------------------------
SKIN:Skin as a respiratory medium, needs to be thin, wet and cover large surface area than volume. The Skin fulfills all these Prerequisites, thus it is a perfect organ for the respiration. Even our respiratory medium which is alveoli is wet, thin and cover REALLY large surface area more than our body. If the skin dries, there will be no diffusion and worm will die due to dessication.
_____________________________________Best Regards,'Borz'Would each of these scenarios be addressed through engineering design or scientific inquiry? 4. A commercial strawberry grower is having a problem with her greenhouses overheating in the summer months. 5. A new species of plant is discovered. Botanists want to know why it only grows in certain areas of the rainforest. HighLighter PopupUnderline Selected TextGreen Color HighlightOrange Color HighlightYellow Color HighlightBlue Color HighlightPink Color HighlightRemove Color Highlight
Answer:
See the answer below
Explanation:
A greenhouse overheating in the summer months has everything to do with engineering design and must be addressed as such. Since the commercial strawberry grower has already established the problem of overheating of the greenhouses, the solution to the problem lies with checking the engineering design of the greenhouses and not in making a scientific inquiry. The problem has been detected and a solution has to be provided by checking the fault in the design that could be causing the overheating.
Botanists trying to know why a newly discovered species of plant only grows in certain areas would need to carry out a scientific investigation/inquiry in order to get answers to their enquiry. Several questions might be raised as to why the growth of the plant is limited to those areas and these can only be answered by conducting scientific investigations.
CAN SOME ONE HELP ME WITH 8-12 PLZ!!!!!!!!!!!!
Answer:
8.Active Transport
9.phospholipid
10.facilitated diffusion
11.osmosis
12.ATP
Explanation:
Active transport is similar to osmosis but it happens with other substances
The phospholipid is shaped like a ball with two legs coming out and the legs connect on both sides of the cell to help protect the membrane and to help provide pathways.
Facilitated diffusion is just what is happening when the material or substance is going through the membrane which is either active or passive.
Osmosis is when the water passes through the membrane from a less concentrated place to a high concentrated place
ATP is energy used to help material or substance through the cell however only certain types of material need the energy to pass through some don't require energy at all

does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy! i need a claim n evidence!!!
Answer:
Explanation:
This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.
The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source".
The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.
However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.
Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .

What is described by a rate of diffusion?
Answer:
The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.

Is it possible for energy to be transferred directly from the first trophic level to the third trophic level? Explain.
During energy transfer, 10% of the energy is transferred to the next trophic level and 90% is lost to the environment. Energy transfers from one trophic level to the next trophic level and not the third trophic level.
What is Energy transfer?Energy transfer is the amount of energy at each trophic level which is transferred to the next trophic level. Energy decreases as it moves through an ecosystem. As little as 10% of the energy at any trophic level is transferred to the next level and the rest is lost largely through metabolic processes as heat energy.
From each trophic level to the next trophic level, about 90% of the starting energy is unavailable to the next trophic level because the energy is used for different processes such as movement, growth, respiration, and reproduction and some energy is lost as heat.
