Astudent is looking at a paramecium sp. using a compound light microscope. she turns the iris diaphragm to adjust

the brightness by controlling the amount of light beaming through the image

the objective lens and increase the magnification of the image

the electrons beamed through the image to regulate the brightness

the position of the paramecium sp. on the slide in order to center it for maximum magnification

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
