Answer:
B. Codon
Explanation:
Codon- a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
Carbon dioxide is transported in the blood in three ways: (i) dissolved in solution; (ii) buffered with water as carbonic acid; (iii) bound to proteins, particularly haemoglobin. Source: https://academic.oup.com/bjaed/article/5/6/207/331369
Evolution occurs when<span>these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift

Humans have an impact on species migration both through climate change and by changing the landscape. ... Both plants and animals will have to respond to the changing climate. In some cases, this means adapting to higher temperatures.
