first one is definitely a fact
The correct answer is letter (<span>C) The polar air mass moves south to replace the rising maritime tropical air mass.</span> These air masses are bringing cold air to warmer areas most especially during the winter and cool. These air masses are stable and usually does not form much cloud. While the Continental Polar air move down south, across the warmer land, the lower part of the air mass is modified and thus few clouds are formed.
Yeah I can help with that
Answer:
exposure to ultraviolet radiation is a correct answer.
Explanation:
Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.
Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.
The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.
The sun gives direct energy and sunlight to the producer. The producer will grow until it reaches adulthood. A consumer will come eat from that said producer and receive its energy.
