Answer:
B. Ribosome
Explanation:
Ribosomes are the organelles that serve as a site for protein synthesis. Each ribosome has two subunits. The small subunit first joins with mRNA and the initiator tRNA to start the process of protein synthesis. The large subunit joins the complex and the proteins are synthesized according to the nucleotide sequence of the mRNA read in the form of genetic triplets. Ribosomes are present in cytosol as well as on the surface of the rough endoplasmic reticulum of a eukaryotic cell. In both locations, they are involved in the process of protein synthesis.
Climate change
Greenhouse effect
Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.
These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.
Increasing carbon dioxide levels
Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.
Global warming
The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.
The answer is catastrophism.
Catastrophism is a theory explaining that the Earth has been affected by sudden catastrophes which created its geological features. Some of the proposed catastrophes is a global flood followed by an uplifting of some rock which happened sudden, in a short period of time. It is opposite theory to uniformitarianism which explains that the Earth was formed in slow changes.
I found some articles on the internet that may be helpful (took me three minutes of searching). Hope these help?
