Answer:

The Scientific method is the process people go through to answer a question using science.

Explanation:

In the scientific method they're usually six steps to solving your question:

Ask a question
Do your research
Make a hypothesis
Conduct a experiment to test your hypothesis
Analyze and draw a conclusion using the data found from your experiment.
Share your results.

Finding a answer to a question using science requires work. You need to first find your question, and then do your research on that topic to find out how you can find the answer for yourself. Make a prediction on the answer, and conduct a experiment to test your prediction, have multiple trials to insure you have valid results. Then finally analyze your results and use the data you find to draw your conclusion/answer to your question.

Hope this helps.

Place the events in the correct order:

Alecsey [184]

Answer:

1. Chromatin condense into chromosomes.

4. Homologous chromosomes pair up (formation of tetrads).

5. Homologous chromosomes separate and move to poles.

2. Sister chromatids separate.

3. Chromosomes unravel in to chromatin.

Explanation:

This question portrays the process of meiosis in a cell. The ordered sequence of events in the options are:

1. Chromatin condense into chromosomes - This process occurs in the Prophase stage. Prior to the cell division, the nuclear material is found as Chromatin material. This Chromatin material then undergoes condensation to form visible chromosomes.

4. Homologous chromosomes pair up (formation of tetrads) - This process also occurs during the Prophase stage of meiosis I. In this stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) are paired up side by side to form a structure known as TETRAD or BIVALENT.

5. Homologous chromosomes separate and move to poles - This process characterizes the Anaphase stage of meiosis I. Homologous chromosomes are pulled apart to opposite poles of the cell by spindle microtubules.

2. Sister chromatids separate - After meiosis I, meiosis II involving sister chromatids instead of homologous chromosomes follows. In the Anaphase stage of meiosis II specifically, sister chromatids are pulled apart towards opposite poles of the cell.

3. Chromosomes unravel in to chromatin - After the whole division process i.e. karyokinesis (division of the nuclear material), the chromosomes begin to unravel to form the CHROMATIN threads once again. This process occurs in the Telophase stage of meiosis.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe

dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.

The equation can be written as, $F= K \frac{ q_{1} q_{2} }{r^{2} }$ where k is the Coulomb constant, $q_{1} q_{2}$ are the point charges, and r is the distance between these two point charges.
To find the answer to this question, just substitute 2r in the place of r hence, you will get $\frac{F}{4}$ as the new force when the distance is doubled.
