Plasma membrane is the answer
<span>The action that researchers take to make advances in science would be conducting experiments to test their hypothesis. By doing such, they are able to know whether the hypothesis is true or not. Hope this answers the question. Have a nice day.</span>
Answer:
The first fossils were marine reptiles called plesiosaurs. They were found on Seymour Island in 1982. The first dinosaur fossil was an ankylosaur, found on James Ross Island in 1986.
Explanation:
In this case, you are given the density( 11.3g/cm3) and the weight (1kg) of the lead. You are asked to find the volume of the lead.
To find volume you need to divide the weight with the density. It would be:
volume= weight/density
volume = 1kg x (1000 gram/kg) / (11.3g/cm3)= 88.495 cm3
