The answer is A and by the way, you spelled his first name wrong. It's spelled Louis.
Answer:
Chloroplasts are organelles that are filled with a green substance known as Chlorophyll. Chloroplasts are what convert water and sunlight into sugar/food, in a process known as photosynthesis. Plants can't hunt or gather food, so they make their own through chloroplast's. The Mitochondria are the powerhouses of cells.

The outer volume of the atom (which means most of the atom) is occupied by electrons
<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The
other type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted
horizontally parallel to the ground. It is constantly aligned with the wind
using a yaw-adjustment mechanism. This mechanism moves the entire rotor left or
right in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. The motion that converts into electricity is the
rotor. The answer is letter D.</span>
Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.
Explanation:
Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.
Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.
