Answer:
a. A hypothesis that does not generate a testable prediction is not useful.
Explanation:
In the scientific method, we generate a hypothesis to explain a phenomenon. After this, it is necessary to create a method to test the hypothesis and make predictions. Moving forward, we test this methodology, generating results and reject or not reject the hypothesis. If the hypothesis can't be tested, the scientific method can't be applied.
The statement environmental influences begin at birth and continue throughout life is definitely False.
<h3>What do you mean by Environment?</h3>
Anything which is present in the surrounding of an organism is called its environment. The environment is surrounded by abiotic and biotic factors.
Environmental influences will not remain the same throughout life. If a human is affected by a natural disease, it will definitely be cured with medications. Environmental influences sometimes behave as genetic diseases, which stay long or sometimes endless.
Therefore, the statement environmental influences begin at birth and continue throughout life is definitely False.
