Iwill give brainiest user.2b. calculating magnification: magnification describes how much larger an object appears when viewed through a microscope than its actual size. the eyepiece and the objective lens are the two magnifying features of every microscope. scanning objective=4x, low-power objective= 10x and high-power=40x.(eyepiece magnifies image 10x(times) its actual size. 2c. calculate the total magnification of the daphnia/water flea under each lens. eyepiece x scanning objective = total magnification eyepiece x low-power objective = total magnification eyepiece x high-power objective = total magnification question: what is its actual size under each lens?

Given,  

Magnification of eyepiece = 10x  

Magnification of scanning objective = 4x  

Magnification of low power objective lens = 10x  

Magnification of high-power objective lens = 10x  

Magnification of the microscope can be determined by using the following formula:

[Where Mo is the magnification of the ocular lens and the Me is the magnification of eyepiece and M is total magnification]

Total magnification of Daphnia under scanning objective (Ms)

Total magnification of Daphnia under low power objective lens (ML)

Total magnification of Daphnia under high power objective lens

An average size of daphnia is 3mm

So, Total magnification of Daphnia under scanning objective = 40x

Total size of daphnia after magnification would be =  

Total magnification of Daphnia under low power objective lens = 100x Total size of daphnia after magnification would be =  

Total magnification of Daphnia under high power objective lens = 400x Total size of daphnia after magnification would be =

that is wrong, its not thymus.
