If there was a sudden drop in temperature after the evolution of the
first living cells, the rate of fermentation would drop due to the
temperature. My prediction would have to include the data, which is on
the graph. The question does not include a temperature to base my
hypothesis on so I would have to conclude that if the temperature
suddenly dropped to 35ºC to -20ºC, that the initial cells would die, and
that the atmosphere and the evolution of cyanobacteria would change
drastically.
Answer: 1000 nm
Explanation:
Bacteria are the type of biological cell. They constitute a large domain as they are found every where on the earth.
These are few micrometer in length which means 200-700nm . It depends on the type of the bacterial cell. The bacteria are the first organism that appeared on earth.
They are found in water, on land, desert, hydro thermal vent, snow et cetera. These are variable in shape.
<span>The appropriate answer is c. sonar. Oceanographers use sonar to determine the ocean depth. A sonar signal is sent from the ship. Oceanographers record the time taken for the signal to leave the ship and for it to return. Knowing the speed of sound in water, they are able to calculate the depth of the water. This method is also used to generate bathymetric images of the ocean floor. </span>
