Answer:
The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.
Explanation:
The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.
Answer:
Separation of homologous chromosomes occurs after the formation of tetrads, during anaphase I of meiosis. ... Both divisions require the condensation of chromosomes and eventual cytokinesis to produce daughter cells. Sister chromatids are separated during anaphase of mitosis, and during anaphase II of meiosis.
Answer:
The scientist must complete the experiment, evaluate the results and disclose his conclusions.
Explanation:
If the scientist wishes to find conflicting data in a widely accepted theory, he must first establish a scientific experiment using all the steps of the scientific method. It is important for the scientist to complete the entire experiment so that he can evaluate the results and reach concrete conclusions about whether there is, in fact, conflicting data in the theory. The results should generate conclusions that must be disclosed regardless of whether the cinetist's hypotheses are proven or not.
The scientific method is a set of rules that guide the execution of a scientific experiment.
