The hardest coal has the most energy and burns the cleanest. Where do coal miners find the HARDEST coal?
A. on the surface of the earth
B. in the oceans
C. deep beneath the earth’s surface
D. at the bottom of shallow lakes and rivers
Answer:
C
Explanation:
This coal will be more compact and therefore most of the water and CO2 has been expelled due to this. This coal is called Anthracite and burns the cleanest. It is often found in areas with high stress and lots of pressure so mainly far underground. Why do you think the the majority of mines are underground and not open sites? So that they can get to the best coal the most economic and ergonomically way possible
Mario and several friends spend a day at the beach. While watching the ocean waves crashing to shore, Mario wonders how much of the world's water is contained in different types of bodies of water such as oceans, lakes, and rivers. He decides to research the percentage of Earth's water found in different locations. Which does his research reveal? Multiple choice question. A) Less than 3 percent of Earth's water is freshwater containing no salt. B) The ice caps located at both poles contain 30 percent of Earth's water. C) Fifty percent of Earth's water is in oceans and the glaciers at the poles. D) Ninety percent of Earth's water is in lakes, rivers, and groundwater.
Answer:
A
Explanation:
The correct answer here would be that less than 3 percent of Earth's water is freshwater containing no salt.
Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms.
The correct option is A.

what does DNA use to store information
Answer:
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Explanation:
DNA uses the complimentary base pairs to store information in organisms.
The base pairs comprises of the nucleic acid include adenine (A), thymine
(T), cytosine (C) and guanine (G) .
The base pairs contain unique amino acid sequences which represent a
unique trait in organisms. Any alteration in this pair will lead to a different
result or mutation which is why it is very important and has to be rightly
paired .

How do nutrients move through an environment? What drives the movement of nutrients?
Answer:
The nutrient cycle is a system where energy and matter are transferred between living organisms and nonliving parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.
The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment.
How do nutrients move?As the concentration of nutrients around the root system decreases, nutrients from higher concentration areas diffuse - or move - toward low concentration areas and the roots. They only move a short distance, however. Potassium (K) and phosphorus (P) primarily move via diffusion.The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment. This occurs when animals and plants consume soil nutrients, which are then released back into the environment through death and decomposition.The movement of nutrients to the root surface in response to a concentration gradient is referred to as diffusion. When nutrients are found in higher concentrations in one area than in another, there is a net movement to the low-concentration area, resulting in equilibrium.To learn more about : Diffusion.

How are photosynthesis and cellular respiration related?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
I hope that helps determine your answer.
The product of photosynthesis are the reactants of cellular respiration.
What is cellular respiration?Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.
This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.

Check Some flatworms reproduce through fragmentation. What is a disadvantage of this method?
1.) It is a very slow process relative to sexual reproduction.
2.) It is a process that leads to lower genetic diversity than sexual reproduction
3.) It is a process that does not result in many offspring relative to sexual reproduction
4.)It is a much more complex process than sexual reproduction.
Answer:
it is a process that leads to lower genetic diversity than sexual reproduction
Following are the disadvantages of this method:
It is a very slow process relative to sexual reproduction.It is a process that leads to lower genetic diversity than sexual reproduction.Fragmentation is a method of reproduction that occurs when an organism breaks into smaller pieces, which then grow into new individuals. While this process can be efficient in certain circumstances, it has several disadvantages compared to sexual reproduction. One disadvantage is that it is a very slow process relative to sexual reproduction. This is because it takes time for the fragments to grow and develop into new individuals, and there may be many steps involved in this process.
Additionally, fragmentation leads to lower genetic diversity than sexual reproduction, because the offspring are identical to the parent organism, rather than being the result of a mixing of genetic material from two different parents. These factors may make fragmentation a less effective method of reproduction in some circumstances.

Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
Answer:
See the answer below
Explanation:
Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
What is the dependent (data) variable?
A. Location of cups
B. Amount of time they were left in locations
C. Amount of evaporated water
D. Size of cups
The dependent variable is the variable whose value is dependent on other variables, particularly the independent variable, in the course of experiments. As the independent variable becomes varied during the experiment, the value of the dependent variable also varies along.
Hence, in this particular scenario, the dependent variable would be the amount of evaporated water. This amount would be dependent on the location of the cups around the house which, in this case, would be the independent variable.
