"The number of chromosomes present in a diploid cell doubles for each generation because there are two parent" is the one among the two statements that <span>is the best explanation for why the chromosome numbers above are all even. The correct option among the two options that are given in the question is the second option or option "B". </span>
Answer;
The fibrous pericardium is not distensible, which causes the blood to put pressure on the heart, constricting it and reducing its ability to contract

Pick a topic.
Research.
Hypothesis.
Experiment.
Construct an exhibit for results.
Write a report.
Practice presenting.
Pick something you are interested in, something you'd like to think about and know more about
Then do some background research on the topic.
Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.
Design and carry out your research, keeping careful records of everything you do or see and your results or observations.
Construct an exhibit or display to show and explain to others what you hoped to test.
Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.
Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

Answer:
A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.
Cells<span> need a source of </span>energy<span>, they </span>get<span> this </span>energy<span> by breaking down food molecules to release, the stored chemical </span>energy.This process is called 'cellular<span>respiration'. The process is happens in all the </span>cells<span> in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).</span>
