Explanation:
The way in which a living organism or bodily part functions.
The branch of biology that deals with the normal functions of living organisms and their parts.
Answer:
mRNA: A-U-G-C-A-U-U-A
Explanation:
Given DNA template: T-A-C-G-C-T-A-A-T
Newly transcribed mRNA: A-U-G-C-A-U-U-A
Transcription is a process that uses DNA template strand to make RNA strands. The process occurs in nucleus. The nucleotide sequence of DNA template is always complimentary to its respective RNA sequence.
Here, thymine of DNA template strand pairs with adenine of newly formed RNA. Adenine of DNA template would pair with uracil of RNA. Guanine of DNA template pairs with cytosine.
Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.
• Droughts are becoming longer and more extreme around the world.
• Tropical storms becoming more severe due to warmer ocean water temperatures.
• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.
• Overall, glaciers are melting at a faster rate.
• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.
• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.
• Sea levels are rising, threatening coastal communities and estuarine ecosystems.
