A field of grass plants is contaminated by lead, and measured levels of 1 ppm. (parts per million) of this lead. Ench yashopper in the field eats 12 grass plants over its lifetimes, and each dove consumes 6 of these yrasshoppers. The wop predator in that area is
he hawk, and each hawk consumes 10 dove. How many ppm. of lead would each hank accumulate in their bodies? Share your

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

i think its both a and b
