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!

-Examples of polygenic inheritance in nature can be found in many places: in human height, skin color, and hair color; in animal size, longevity, or disease resistance; and in plants with grain color, length of maize, or flower size. All of these traits are influenced by multiple genes and considered polygenic.

The snake contains 1,000 joules of energy. How much energy will the hawk effectively use upon eating the snake?
labwork [276]
Only 10% of the energy is transferred from one level to other,
so,
10% of 1,000J = 100 J
Which means 1000-100 = 900J of energy is used upon eating the snake.
(I’m not 100% sure about this answer though, but I think it will give u a good idea about energy transfer)
