No, because the question cannot be tested in a laboratory. Yes, because the question has already been answered. No, because the question does not lead to a hypothesis.
Answer:
Yes, because the question is specific.
Explanation:
The given question is scientific because it comprise of logic and reasoning, this question only be answered after performing experiments in the laboratory in order to find the factor behind the change of color. The question is specific because it only occurs in hare and we have to know that this change in color occurs due to change in temperature of the environment or not. So we have to perform scientific investigation.

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.
How fast do particles move in a liquid?
Answer:
In liquids, particles are quite close together and move with random motion throughout the container. The particles move around fast in all directions but run into each other more than gas particles because they're more tightly compact.

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.

can anybody help me with this?
Answer:
presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits
in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance
sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them
the sugar dissolves in water, creating a sugar solution
this results in fruits with less water inside them, and surrounded by sugar solution

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).

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.
