A sperm cell has a tail 40 micrometers long and a student draws it 40mm long. Calculate the magnification

The formula for calculating magnification is:

Magnification = Size of drawing / Actual size

Size of drawing = 40 mm

Actual size = 40 micron meter

Convert 40 mm to micron unit: 40 * 1000 = 40,000 micron

Magnification = 40,000 / 40 = 1000.

The magnification is 1000 X.

This answer means that the drawing is 1000 times bigger than the actual size of the cell.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
