Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.
Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.
Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.
Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.
Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.
Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.
Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.
Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.
The answer is C. 24.
It is the answer because diploid cells have double the amount as haploid.
Answer: C. Humans have avoided animal habitats.
Explanation:
Emerging diseases are those diseases which occur frequently after a single tenure of infection. These disease poses a serious challenge over the immune system of the body and it becomes incapable of recovery and can also be lethal.
Humans have avoided animal habitats. is the correct option this is because of the fact that on rare instances the association of animals was proven to be infectious to humans. Thus animal habitat avoidance cannot prove to be the concern for the re-emergence of a disease.
Lets understand that biotic factors are living and abiotic factors are non living.
1. I see a fish and plants
2. The water
3. The biotic factor which is the fish interacts with the water which is abiotic by swimming and breathing it in with its gills.
4.The plant which is a biotic factor could be taken out. This would affect the aquarium because the fish would have nothing to feed on.
5. One abiotic factor you could change would be the water. You could take it out and the biotic factors wouldn't survive without it.
