<h2>Solution:</h2><h3>Given data:</h3>
d= 20g/cm3
m= 10g
formula: d= m/v
By rearranging the formula according to our need:
v= m/d
by putting the values in the formula
v= 10g/20g/cm3
v= 0.5L
So, a rock that has a density of 20g/cm3 and a mass of 10 g would have the volume of 0.5L.

If a repressor protein attaches to the operator, RNA polymerase cannot proceed to transcribe key enzymes needed by the organism. This can be seen in the trp operon in E .coli bacteria.
The Earth comprises many spheres of subsystems, which associate with each other to develop a composite and spontaneously changing system of the Earth. The processes taking place in the system of the Earth occurs on spatial scales changing from fractions of millimeters to thousands of kilometers, and on time scales, which varies from milliseconds to billions of years.
The examples of instantaneous scales are a rotation of the Earth, breathing, an earthquake.
The examples of long-term scales are making coal and plate tectonics.
The system of the Earth is featured by various overlapping cycles in which matter is recycled again and again. The cycles involve interactions between multiple spheres and systems. The examples of cycles are rock cycle, day and night, and seasons.
Volcanoes discharge a huge concentration of particulate matter into the atmosphere. These particles function as nuclei for the development of droplets of water (hydrosphere). The rainfall, that is, hydrosphere usually upsurges after an eruption, initiating growth of the plant (biosphere). Thus, volcanoes and volcanic activities are a good illustration of system interactions.
