Answer:
Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.
<span>Apart from the plants and algae which are well-known to be able to perform photosynthesis, other organisms capable of doing so are some specific species of bacteria especially those which contain the green pigments called chlorophyll necessary for photosynthesis. These bacteria are also capable of absorbing carbon dioxide.</span><span />
Microscopic anatomy
The study that uses microscopes to see the minute details of organ parts is called microscopic anatomy.
Microscopic anatomy is the study of cells, tissues and organs of the body that are too small to been seen with the naked eye. Microscopic anatomy usually involves using special staining techniques, combined with electron or light microscope. The use of stains helps to improve colors so that the cells can be more easily identified when they are examined.
C. crossing over This is because each gene have a piece of each other Hope this helped=)
Answer: c. are spliced out of the message.
Explanation: Intron are non-coding portion of the DNA sequence. They do not code for any specific amino acid and are spliced or removed before splicing.
Exons are DNA sequence that code for specific amino acid they are usually left after introns are removed and are joined together before translation into amino acid sequence. Intron splicing can lead to splicing some exons which can lead to formation of an entirely new amino acid or protein.
Spliceosome are enzymes for splicing introns.
