1. Answer;
Light microscope (LM)
Explanation;
-A light microscope (LM) is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows.
-It allows attachment of the focus wheels and the stage to the microscope. A light source used in place of a mirror. Most microscopes do allow manual light adjustment via a wheel located near the base.
2. Answer;
Scanning electron microscope (SEM)
Explanation;
-A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. The electrons in the beam interact with the sample, producing various signals that can be used to obtain information about the surface topography and composition.
-There are two main types of electron microscope; the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image.
Answer: The correct answer is -
d) a dominant trait that depends on the presence of only one of many dominant alleles.
Glaucoma is an autosomal dominant trait, meaning that presence of single copy of the defective gene is enough to cause the disease.
