Answer:

A scientific experiment refers to a detailed and organized array of steps that are needed to reject or validate the framed hypothesis. The steps, which are incorporated in a scientific experiment are:

1. Identification of independent variable: The independent variable is the one that can be manipulated or changed in an experiment, that is, the effect of which can be witnessed on a dependent variable.

2. Address any confounding variable: It is the one that comes from the outside, the changes resulting due to this variable impart an effect over the independent and dependent variables. This variable can bring change in the outcome of the experiment.

3. Form a non-falsifiable hypothesis: A non-falsifiable hypothesis refers to the one that can be proved true on the basis of the implementation of suitable methodology and research design.

What will a hypothesis become if supported by repeated expermentation

Dovator [93]

Answer:

Answer: The correct answer is- Theory.

Hypothesis can be described as an assumption or proposition, which is made on the basis of certain evidences without knowing the real truth about it. It is tested further for investigation about the proposed explanation with the help of repeated experiments (using certain protocols).

When it becomes supported by repeated experimentation, it is converted into theory.

Thus, theory is the right answer.

In the female, the development of the "egg" halts during TWO stages, _________ and __________

earnstyle [38]

Answer: The blanks can be correctly filled up with prophase I and metaphase II.

Explanation:

In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.

After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.

Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.
