Answer:
The answers are Fluorine and Francium.
Explanation:
Fluorine has the highest affinity for electrons while Francium has the lowest affinity for electrons. This can be measured by the electronegativity of each one, where Fluorine is the most electronegative element. This can also be seen by the accommodation of elements in the periodic table.
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.
Answer:
Deletion
Explanation:
ATGCCATG<u>G</u>CATTGA
-->
ATGCCATGCATTGA
Comparing the two sequences, you can see that one G nucleotide is missing in the new sequence compared to the original.
This is a single nucleotide deletion, where one nucleotide is lost from the sequence. Otherwise, the sequence is entirely unchanged.
There are two hydrogen atoms in a molecule of water.
