cycling:
Answer:
Explanation:
Chemical cycles typically involve three general steps: ... As organisms die, decomposers break them down, further supplying the soil, water, and air with chemicals in inorganic form. The producers gain a renewed supply of raw materials for building organic matter, and the cycles continue.

Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).
Answer:
The experiment consists of three different treatments:
1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth
2- Fifty (50) no treated chili pepper plants that grown in normal conditions
3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)
Dependent variable: plant growth
Independent variable: the amount of substance x (suspected to slow down plant growth)
Explanation:
The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.
Hypothesis development for substance.
A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.
Thus the answer is slow growth, normal growth, and positive fast growth.
The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.Learn more about the scientist's development.

Which correctly lists three greenhouse gases?
oxygen, carbon dioxide, helium
carbon dioxide, nitrous oxide, methane
helium, methane, oxygen
methane, oxygen, carbon dioxide
Answer:
carbon, dioxide, nitrogen oxide, methane
Explanation:
fz f..
The correct list of greenhouse gases is: carbon dioxide, nitrous oxide, methane.
GREENHOUSE GASES:Greenhouse gases are gases capable of trapping heat in their bonds and releasing it into the atmosphere.
Greenhouse gases are the major cause of global warming, which is the increase in the average temperature of the atmosphere.
Greenhouse gases include the following: carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2), sulfur dioxide (SO2) etc.

Why are most stray cats short hair cats, but a variety of colors?
According to the American Humane Society, roughly 95% of all cats are short hair cats (called domestic shorthair). This applies not just to strays but cats that have owners as well. So that fact alone is enough to be able to see why most strays are short hair cats.
Through my research, I'm reading that some people claim that long hair cats are more expensive and rare cats, so the owner is likely to take better care of them and keep them indoors. This further inflates the percentage of stray short hair cats out on the street. I couldn't find much about this from an official source, but instead just through forum posts.
As for the colors, I'm not entirely sure. The cat's fur color comes from its genetics. So it's possible that darker more earth-tone colors help the animal survive better compared to say a lighter color or white fur. Due to natural selection and survival of the fittest, the darker hair color cats will eventually out-number the lighter fur colors. That's my theory anyway. I couldn't find much data or studies to back that up.

What is difference between unicellular and multicellular organisms?
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore, all cells have a cell wall but only plant cells have a cell membrane. The given statement is false.

Both lipids and carbohydrates can be used by the cell as -
A. O replacements for salts.
В.
catalysts for metabolic reactions.
c. building blocks for RNA.
D
sources of energy.
D both can be used as sources of energy
The similarity between lipids and carbohydrates is that both are classes of chemical compounds that are found in living things. Thus, option D is correct.
What are the use of lipid and carbohydrate?Two of the four significant biomolecules include lipids and carbohydrates. They are both sources of energy.
However, although lipids store energy for later use and release it more slowly, carbs are available as instant energy sources. Thus, this is the primary distinction between lipids and carbs.
More energy is stored in lipids than in an equivalent mass of carbs. To release their energy, however, carbohydrates are easier to digest than lipids.
This indicates that they are made up of many carbon atoms with bonds to oxygen and hydrogen.
Therefore, Both lipids and carbohydrates can be used by the cell as sources of energy.

What do scientists do when experiments are not possible
Answer:
Well, to be honest I think that they might just figure out another way to do that experiment.
Explanation: My reasoning is, that if an experiment isn't possible due to complications like maybe it could be to dangours or it could have reaction that they don't know about. So if they aren't able to do an experiment then they might find a safer one to do or they might just skip it and research more about it and see how it would react to certan things.
