You can restore damaged ecosystems by planting trees on land where forests have been cut down. Or you can encourage people around you to live in ways that don't hurt the environment.
Explanation:
<h3>The amino acid sequence of tyrosinase from neurospora crassa </h3>
<em>monophenol,</em><em> </em><em> </em><em>dihydroxyphenylalanine,</em><em> </em><em>oxygen</em><em> </em><em>oxidoreducatase </em><em>.</em>
Answer: 2.3 g cm^3
Explanation: In this case the rise in level of water is same as the volume occupied by the stone.
a) Volume occupied by the stone = 70 cm^3 – 40 cm^3= 30 cm^3
b) Density = mass/volume
= 69g/30 cm^3 = 2.3 g cm^3
Layer that is 0.2 to 1.1 percent of Earth's total diameter is the thinnest layer of the Earth- Crust.
So, the correct answer is: oxygen and silicone. The crust consists of tectonic plates (in relative motion one from another) and has 5–70 km (~3–44 miles) in depth. The most abundant elements of this layer are: oxygen-46.6 percent by weight; silicon-27.7 percent; aluminum-8.1 percent; iron-5 percent.
