What are Renewable and Non-Renewable resources?Resources are divided as renewable or non-renewable. A renewable resource can renew itself at the rate it is used, while a non-renewable resource has a limited supply. Examples of renewable resources are timber, wind and solar while non-renewable resources are coal and natural gas.
Renewable energy is the energy which can be used repeatedly and it is renewed again after a short period of time which is defined as the type of energy resources that can be renewed naturally. Renewable sources of energy can replace the conventional sources of energy which produce harmful gases which are harmful as well as costly.
Non-renewable resources are those which cannot be reused or reproduced, it is used only once and takes a long time to reproduce. These are also not good for the environment. Burning fossil fuels harms our environment.
Thus, Solar Energy would best be categorized as inexhaustible. So, the correct option is (C).

how can an error in dna get us sick?
Pleaseeee explain!
Answer:
Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.

Group A was given chocolate right before their test and Group B was given nothing before the test. The test average for Group A was 85% and the test average for Groups B was 64%. What is the independent variable?
A. Group A
B. Group B
C. Chocolate
D. Ms. Brown
Answer:
group A
Explanation:
An independent variable is a variable in a functional relation wherein the value is not affected by other variables. That is in contrast to a dependent variable that is influenced by other variables. independent variable science definition: the variable in a functional relation wherein the value is independent.

How do animals obtain usable nitrogen? Why is it important?
Nitrogen in Plants
Nitrogen in PlantsNitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins
Answer:
Through eating plants and animals.
Explanation:
Usable nitrogen is not achievable simply. It can also not be obtained directly. Animals must receive nitrogen from consuming plant-based foods (plants) or other animals.
Nitrogen is significantly relevant/important to animals and plants since nitrogen produces proteins to these animals and chlorophyll to the plants. Nitrogen also helps with the growth and creation of DNA towards animals and plants.

Why do you think toxicology is an important area of study in veterinary science?
Because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.
What is veterinary science?Veterinary science is defined as concerned with preventing the spread of animal diseases to humans as well as the prevention, control, diagnosis, and treatment of diseases impacting the health of domestic and wild animals.
Toxicology is defined as a branch of study that aids in our comprehension of the negative consequences that drugs, events, or chemicals may have on humans, animals, and the environment. The Threshold of Toxicological Concern (TTC) is a notion that refers to the determination of a level of exposure for all chemicals beyond which there would be no appreciable danger to human health, whether or not there are chemical-specific toxicity data.
Thus, because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.

carbs are made up of which monomer?
Answer:
monosaccharides
Explanation:
Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.
Answer:
The most common polysaccharides are built solely with glucose monomers, while significant structural differences between these polysaccharides arise mainly from the position and number of the glycosidic linkages in each glucose unit.

If you have a container with hydrogen atoms and oxygen atoms in it do you automatically have water?
Answer:
no
Explanation:
you have to have the right amount and the right situation for it to turn into water. for instance The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
