Answer:
Shows comparative homologous structures among different species.
Explanation:
The picture is showing the bones of forearms of different species. Structurally they appear the same but they serve a different purpose.
-- Perihelion . . . Point in Earth's orbit where we're closest to the sun.
We get there sometime during the first few days of January.
-- Aphelion . . . Point in Earth's orbit where we're farthest from the sun.
We get there sometime during the first few days of July.
-- Perigee . . . Point in the orbit of the Moon or any artificial satellite
where it's closest to the Earth.
-- Apogee . . . Point in the orbit of the Moon or any artificial satellite
where it's farthest from the Earth.

Explanation:
Leprosy, known as Hansen’s disease, is a chronic infection that is caused by Mycobacterium leprae. This disease damages peripheral nerves and effect areas like skin, yes, muscles and noses. Antibiotics are used to treat the infection between 6 – 12 months. When infected people refuse to follow the treatment schedules given to them by the medical experts, there is usually the development of more antibiotic-resistant M. leprae.
M. leprae, just like tuberculosis, cell walls contain fatty molecules known as mycolic acids, which make the bacteria less susceptible to antibiotics.
Researchers have made remarkable progress in developing drugs such as ethionamide, isoxyl, thiolactomycin, and triclosan that are known to inhibit mycolic acid biosynthesis.
The development of these drugs are part of the tuberculosis drug discovery efforts (in the last one decade) which has been successfully applied to therapeutic targets in the unique mycobacterial wall.
Since morphology and cell wall of M. leprae does not differ remarkably from that of M. tuberculosis, antibiotic developed to inhibit the biosynthesis of mycolic acids would help to treat leprosy
In my opinion, chloroplasts and mitochondria can't live outside the cell now because mitochondria ensure the energy for the cell and the chloroplasts is important for photosynthesis. Just my opinion.
