The molecular clock is a scientific technique which presents a means of estimating evolutionary rates and timescales using genetic data. It uses mutation rate of biomolecules when two or more life forms diverged to estimate the time. Answer is B.
Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
Explanation:
This statement is true, because the warmer the temperature, the faster the atoms move in a liquid
Minerals
Explanation:
Minerals can be found in the cactus and ground and are very resourceful
Answer:
The human population is yet to reach its carrying capacity. However, the following will suggest that humans have reached their carrying capacity.
1. When humans are unable to increase food production which is expected to sustain a larger population.
2. When humans' use of resources, in general, is greater than resource availability.
