Before answering the question, you should know that exons/intron systemin the gene exists only in eukaryotes. A gene can have many exons with introns between them, but in RNA maturation, these exons will be joined together to form one RNA to code for one protein (There's no relation between exons number and how many proteins are formed).

In prokaryotes it is different there's no exons/introns, but their gene can be transcripted to a polycistronic RNA which can give after translation more than one proteins.

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?

Scilla [17]

Answer:

Hope the below helps!

Explanation:

Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.

Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.

I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
