Time for microscopes 101. There are two major types of microscopes; light and electron. In a light microscope the image if seen by refracting light through 2 or more lenses which result in a magnified image of the specimen being viewed. However there are limits to the ability to view these and they are not powerful enough to view very small object. An electron microscope which was referred to in the question works by cutting the specimen to be viewed into a very small piece and then bombarding it with electrons which result in a much clearer and more magnified viewing. HOWEVER, Electron microscopes do not work on living things while regular light microscopes do. Also, due to way how electron microscopes are made they are not common in everyday laboratories and are very expensive to buy. comment below if you need anything else
If there is only 1, x means female and y means male. If there are 3 I'd say 3 x's means female and 2 y's means male. And three x's is female and 3 y's is male. Hope that helps
Knowledge is very important for us for better understanding, for easy study.

What is a body of knowledge that explains the natural world?</h3>
Science is an organized way of using evidence to learn about the natural world. The world science also refers to the body of knowledge that scientists have built up after years of using this process. It is the science with the help of which we can study the nature deeply without and difficulties. It is the science which make the things very easy for us and make for us very easy to be studied. Without the knowledge we can't able to understand the world in a quite easy manner.
So we can conclude that: Knowledge is very important for us for better understanding, for easy study.

Answer:1.Yellow color will be dominant and the ratio is Yellow to green allele is 3:1
2.A recessive test cross should be appropriate.The result will be all yellow colored pea plants.
Explanation:
Since Yy x Yy produces
1YY,2Yy and 1yy then it shows that YY and Yy are 3 yellow pea plants and 1yy green pea plant.
A recessive test cross should be used because a recessive genotype being homozygous can be noticed by its physical appearance
