Answer:
A few basic principles go a long way toward explaining how and why air moves: Warm air rising creates a low pressure zone at the ground. Air from the surrounding area is sucked into the space left by the rising air. Air flows horizontally at top of the troposphere; horizontal flow is called advection. The air cools until it descends. Where it reaches the ground, it creates a high pressure zone. Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
Explanation:
<span>b. photosynthetic organisms provide energy for other organisms on earth.
B is the most suitable answer as photosynthetic organisms get their energy from the sun, and other organisms get their energy from photosynthetic organisms, so the sun is the source of energy for all life.</span>
The answer is <span>C. transcription because this process will transcribe DNA to RNA.
Transcription is a process of transcribing DNA to RNA. Translation is a process of translation mRNA to protein. Therefore, through the process of elimination, the correct choice is C). When an enzyme binds to a sequence of base pairs in DNA, transcription begins. As the result, DNA is transcribed to mRNA which will later be translated to protein during the process of translation.</span>
Answer:
I think it's desertification
The fossil record is the type of evidence that is used with molecular clocks to estimate the split from a common ancestor.
<h3>What is a molecular clock?</h3>
A molecular clock is an estimation of the times of divergence used for the study of biological phenomena.
Molecular clocks are based on fossils found for a given species and the mutation rate of a given genomic sequence.
In conclusion, fossils are used as point of reference to build molecular clocks based on the mutation rate of homo-logous nucleotide sequences for a given taxonomic group for which these fossils belong.
