Answer:
The nucleic acid DNA is an organic compound. DNA is made up of repeating subunits called nucleotides . Each DNA molecule consists of 2 long chains of nucleotides. A DNA nucleotide has three parts: a sugar molecule called deoxyribose ; a phosphate group, and a molecule that is referred to as a nitrogenous base because it contains nitrogen atoms. The deoxyribose sugar and the phosphate group are identical in all DNA nucleotides. However, the nitrogenous base may be any one of 4 different kinds. The four nitrogenous bases found in DNA nucleotides are adenine, thymine, cytosine, and guanine. The two strands of a DNA molecule are held together by hydrogen bonds.

These are biology facts.
Answer: A primary consumer that obtains its energy from the consumption of plants
.
Explanation: This is the only option that makes sense. A monarch is not a producer since it is not a plant. A monarch is not a decomposer of course. Why is it a primary consumer? because monarchs eat from a plant and then are eaten by a secondary consumer.
Explanation:
An ionic bond is formed when one atom (usually a metal) donates its valence electrons to another atom (usually a non-metal) so they attain stable electron configuration. The two atoms become joined by electrostatic forces which result from the charges acquired by the atoms as a result of donating or receiving electrons.
An example is NaCl. Na (2.8.1) donates its one valence electron to achieve the stable configuration of (2.8.8) while CL (2.8.7) receives the electron to achieve stable electron configuration of 2.8.8. The Na is left with a positive charge while Cl is left with a negative charge. The two charged atoms attract each other and form an ionic bond.
