Answer:
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.
Explanation:
Answer:
The correct answer would be A. Condensation, precipitation, runoff, groundwater.
Water cycle explains the cyclic movement of water through the four spheres of the earth.
The water undergoes different physical states while moving through the cycle.
It starts with the evaporation by surface water is transported from the hydrosphere to the atmosphere in the form of water vapors. Transpiration and sublimation also lead to the formation of water vapors in the atmosphere.
The temperature keeps decreasing as the water vapors rise up in the sky. The lower temperature condenses the water vapors into tiny drops which form clouds and fog in the sky.
The tiny droplets accumulate to form bigger droplets and with the combined effect of temperature, wind, and gravity they precipitate in the form of rain, snow, frost, dew et cetera.
The water that falls on the earth surface then runoff into water bodies like stream, lakes, river, seas, and oceans.
Some of the water infiltrates into the soil and form the groundwater.
Density is mass divided by volume
Answer:
inducible operon
Explanation:
the red looks like a active repressor that attaches to and repressed the operon
<span>The gas which was not prevalent in Earth’s atmosphere during the Hadean Eon is CO2. If you are going to see the composition of the Earth's atmosphere, Carbon Dioxide has the least percentage.
</span>This is because after the hydrogen and helium had escaped, Earth's Hadean atmosphere was left with methane, ammonia, water vapor, and small percentages of nitrogen and carbon dioxide.
See attached file for further information about the Earth's atmosphere during the Haedan Period.
