You are given a substance that contains salt, water, and black pepper. a. How would you classify the substance? Justify your answer with evidence. b. How would you classify salt, water, and black pepper individually? Why?
Answer: a. solution.
Explanation:
A solution is a substance which consists of two or more substances. The solute and solvent are the components of the solution. The solute dissolves in a solvent.
a. When salt, water, and black pepper mix together they form a solution. The salt and black pepper are solute and the water is the solvent.
b. salt is a solid. It has a crystalline structure.
water is a liquid
black pepper is again solid
These components will mix together to form a solution.

Oceans formed when rainwater filled basins 3.8 billion years ago. ________ run into the ocean dissolving minerals like salt as they go. __________ leaves salt in the ocean, which is why the ocean is _________. Salinity has _______________, so the ocean is _______getting any more or less salty. Salinity makes water ____________ and contributes to currents.
Answer:
Physically erodes
Minerals
Dissolved
Crystals
Thicker
Minerals
Oceans formed when rainwater filled basins 3.8 billion years ago. Physical erosion runs into the ocean dissolving minerals like salt as they go. Minerals leave salt in the ocean, which is why the ocean is dissolved.
Salinity has crystals, so the ocean is thicker and getting more or less salty. Salinity makes water full of minerals and contributes to currents.
How oceans are formed?The oceans formed billions of years ago due to the condensation of water into rain which significantly filled the basins that ultimately direct the formation of the oceans. Apart from this, the continuous degassing of the interior surface of the earth is also responsible for this fact.
According to the context of this question, the salinity of the oceans depends on the number of minerals dissolved in it which contributes to the development of currents.

The process of diffusion occurs when
A. all molecular movement stops.
B. molecules move from areas of lesser concentration to areas of greater
concentration
C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser
concentration.
Answer:
d
Explanation:
The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.
What is diffusion?The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.
The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.
For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.
Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.

1.Water covers 70 percent of the earth's surface and supports life on the Earth. Explain the statement 2.Why do we need to manage our resources? { i need the answer before 4 pm please help!}
Explanation:
Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.

Osteoporosis is a disease that can cause bone weakening in women due to calcium loss. One group of patients will be taking the regular calcium pill used for treating osteoporosis. Another group of patients will be taking a new calcium pill used for treating osteoporosis. Calcium levels obtained by taking the new pill will be tested over a six month period and the women’s resulting bone mass will be compared between the two groups at the end of six months of treatment.
What is the Independent variable?
Answer:
The Independent variable would be the pills that are being taken.
Explanation:
The Independent variable is the variable that you control because the Dependent variables depend on what the Independent variable is.

explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem
Answer:
The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen

Which is the following is true about saturated fats?
a. They are typically solids at room temperature.
b. They are generally the healthiest fats to consume.
c. They cannot be broken down by enzymes.
d. By definition, they always contain one or more double bonds.
The following is true about saturated fats: they are typically solids at room temperature, which is in Option A, as they have a high melting point due to the absence of double bonds in their fatty acid chain.
What are saturated fats?Saturated fats are a type of fat molecule that consists of long chains of fatty acids. These fatty acids are called "saturated" because they are fully "saturated" with hydrogen atoms, that is, there are no double bonds between the carbon atoms in the fatty acid chain. This results in a straight, rigid structure that allows these fats to pack tightly together, which is why they are usually solid at room temperature.
Hence, the following is true about saturated fats: they are typically solid at room temperature, which is in Option A.
