The troposphere is the layer of atmosphere that contain four major greenhouse gases and therefore, is the site for the greenhouse effect. The greenhouse gases present in the lower troposphere are water vapor, carbon dioxide, methane, and nitrous oxide.
These greenhouse gases trap the radiations reflected back by earth's surface during the night. These trapped radiations serve to increase the earth's atmosphere.
Like DNA, RNA (ribonucleic acid) is a nucleic acid. This molecule is essential in the synthesis of proteins, since it functions as an intermediary capable of expressing the information present in the DNA. The RNA molecule is formed from the DNA molecule in a process called transcription.
There are three types of RNA, which are tRNA, rRNA and mRNA.
Ribosomal RNA (rRNA) is one of the structural components of the ribosome. It is the rRNA that coordinates the interaction between mRNA, tRNA and proteins, during the process of protein synthesis.
The arteries are the blood vessels that carry repeated loads of oxygen-rich blood from the heart to all parts of the body. Arteries are muscular and elastic tubes that operate under high pressure exerted by the pumping action of the heart. The largest artery is the aorta while the arteries' smaller branches are called arterioles and capillaries.
the correct answer is genes
