(WILL GIVE BRAINLIST 2 BEST ANSWER) 1. What is the density of a board whose dimensions are 10 cm long by 5 cm wide by 2 cm tall and whose mass is 28.6 Kg?

So the answer is 2.447357008 x10 -03 g/cm cubed.

Explanation:

a) 5.54 cm times 10.6 cm times 199 cm = 11686.076 (volume= length times width times height)

b) density = mass/volume so 28.6 divided by 11686.076 = 2.447357008 x10 -03

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
