a plant cell is magnified 1000 times using a light microscope.
the length of the image of the plant fell is 10 millimetres.
calculate the actual length of one plant cell in millimetres.
use the formula:
magnification = size of image/size of real object

Which of th following is needed for cellular respiration to occur

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. what can be inferred from these observations? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
