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.
Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
The display of one species that causes the dislike for another species is an example of competition. Details about competition can be found below.
<h3>What is competition?</h3>
Competition in biology is a negative relationship between two or more organisms that leads to the death or injury of involved parties.
Living organisms compete for the following reasons:
According to this question, one species of pufferfish puts on a display for a mate and another species doesn't like it. This indicates that the species of putterfish are involved in a competition.
