1) What is the proper way to carry a microscope? 2) What is the typical magnification of an ocular lens? What other magnifications are possible? 3) What are the magnification abilities of each of the objective lenses? What is the total magnification with each objective? a) Scanning (small lens), red ring = b) Low-power (medium lens), yellow ring = c) High-power (large lens), blue ring = d) Oil immersion (largest lens), white ring = 4) Why do you use immersion oil with 100% objective lens? 5) What is the total magnification of a sample with an ocular lens power of 15X and using a 40X objective lens? 6) What is a diaphragm? What does it do?

 the objective and ocular lenses are responsible for magnifying the image.

so for 10x objective and 10x ocular

total magnification= 10x10= 100x(this means that the image being viewed will appear to be 100 times its actual size)

      a)scanning(small lens),red ring=4x or 5x

      b)low power (medium lens), yellow ring = 10x

      c) high power (large lens),blue ring = 40x

      d)oil immersion (largest lens),white ring = 100-250x

 4.immersion oil helps to focus on lighting

 5. total magnification=15x40 =600x

 6. diaphragm controls the amount of light reaching the specimen.

They control both the focus and quantity of light applied to the specimen.

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.  

explanation:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
