State and explain which is more reactive: Oxygen or Fluorine atom?
Fluorine, higher electronegativity

What is an isomer?
A molecule or atom that has the same chemical formula or composition as another, but a different arrangement of its parts.

What is a condensation reaction? How does it differ from a hydrolysis reaction?
Condensation and hydrolysis are exact chemical opposites. Condensation (or dehydration synthesis) joins two molecules together and releases a water molecule. Hydrolysis uses a water molecule to break a chemical bond and split a larger molecule into smaller parts.

What is the difference between a haploid and a diploid cell?
Haploid cells contain one complete set of chromosomes (n), while diploid cells contain two complete sets of chromosomes (2n).

How does ionization energy change as you move down and to the left of the periodic table? Why?
It decreases! Atomic radius increases as you move down a group, making it easier to remove an electron. Additionally, atoms on the left side of the periodic table have less protons, meaning that there is a relatively smaller positive charge in the center that exerts less pull on the outer electrons.
500
Explain how polarity affects the solubility of a molecule in water.
Polarity affects solubility based on the golden rule that "like dissolves like," meaning polar substances dissolve polar substances, and non-polar substances dissolve non-polar substances. Since water is polar, if a molecule is also polar, it will dissolve.

What is a plasmid and how can it be used by scientists for genetic engineering?
A plasmid is a small circular piece of non-chromosomal DNA. Scientists use plasmids as vectors (delivery vehicles) to carry foreign genetic material into host cells.

Mosquito - it is the most dangerous and deadliest animal in the world, responsible for over 700,000 human deaths each year.
