Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

What is RNA virus?</h3>
- Deoxyribose and ribose, respectively, are the names of the pentose sugars found in DNA and RNA.
- The presence of the hydroxyl group on the 2' carbon of ribose and its lack on the 2' carbon of deoxyribose distinguishes the sugars.
- While the sugar used to construct both DNA and RNA is named deoxyribose (left in the image), the sugar used to construct RNA is simply referred to as ribose.
- Ribose, a 5-carbon sugar, is present in RNA, whereas deoxyribose, a 5-carbon sugar, is present in DNA.
- Both kinds of sugar are crucial parts of nucleotides.
- Pentose sugars, which are a component of DNA, can be found in nucleic acid.

Answer:
Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor
Explanation:
The sensory organs helps to respond to the change in the external and internal environment. The five main types of sense organs are eyes, ears, nose, skin and tongue.
Tongue contains different types of taste buds and taste receptors that helps to distinguish between the different types of food. The receptors are mainly responsible for the taste detection. The student B is unable to taste the bitter molecule because they lacks the receptor.
Thus, the correct answer is option (c)
Population- members of one species living in a particular area
