Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!
<span>Fireflies
use the bioluminescence to attract mates for mating hence key in reproduction.
Therefore, beetles from different species should have different lighting
patterns so that they can only attract mates of the same species. This would
avoid interspecies mating which would probably involved expending energy in
produce nonviable offspring which is inefficient (hence will be unfavoured
natural selection). </span>
Answer:
D
Explanation:
The reproductive system is another word for genital system, which means it would create new species
Gravitational potential energy is the energy an object has due to its position above Earth, energy due to its height. ... The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
