Nitrogen fixing bacteria called rhizobia
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat-trapping causes changes in the radiative balance of the Earth-the balance between energy received from the sun and emitted from Earth-that alter climate and weather patterns at a global and regional scale.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years. Natural Factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

A deep current is colder because it normally doesn’t get as much sunlight as a surface current
Answer:
Every amino acid in the chain changes, making the protein not functional
Explanation:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
