The air begins to rise into the atmosphere. When air rises, it cools down and condenses into precipitation and clouds. This is why an approaching low pressure system means an increased chance for clouds, rain, or snow. It is called "low pressure" because as air rises, the air pressure is lower at the surface.
Answer:During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.
Explanation:
Answer:
<em>The correct option is C) A mouse and a human have about the same number of genes.</em>
Explanation:
The technique of genetic sequencing has enable us to learn and compare thee genomes of different organisms. Genome sequencing proves that the genome of the humans and mice are about 99 percent similar. The number of genes in the mouse genome and the genome of humans is almost equal.
Other options, like option A, cannot be true because many complex organisms have fewer chromosomes than other organisms. For example, there are many simple plants which have more number of chromosomes than the complex humans.
