The answer is the second one (B): Binocular.

Explanation for each option:

  • Parfocal: This term refers to a microscope's ability to stay in focus when the objective lens is changed. It does not describe the number of eyepieces.
  • Binocular: This term describes a microscope that has two eyepieces, allowing the user to view the specimen with both eyes. This is the correct description for the design mentioned in the question.
  • Monocular: This term describes a microscope that has only one eyepiece. It does not match the description of having two eyepieces.
  • Oil immersion lens: This term refers to a specific type of objective lens used to increase resolution by immersing both the objective lens and the specimen in a layer of oil. It does not describe the number of eyepieces.

Summary: The design of having two eyepieces built into a light microscope is best described as "Binocular."

The age/weight relationship of a particular animal can be estimated by the function M(t)=3105 e^(-e^(-0.021(t-53))), where t is the age of this animal in days and M(t) is the weight of this animal in grams. a. Estimate the weight of an animal that is 200 days old. The animal weighs approximately grams when it is 200 days old. (Round to two decimal places as needed.)
