Compare the bones of the upper limbs with those of lower limbs. In what ways are the shapes and arrangements of the bones similar? How are they different?

Bones of upper & lower limbs

Explanation:

The joints of the upper and lower appendages are indistinguishable on the grounds that they fill a similar need with a similar scope of movement, aside from in the respected plane. The bones of the lower appendages are denser and the muscles progressively made to help the heaviness of the chest zone. Bones provide help for our bodies and help structure our shape. Despite the fact that they're light, bones are sufficiently able to help our whole weight.  Bones also ensure the body's organs. The skull secures the mind and structures the state of the face. The spinal string, a pathway for messages between the psyche and the body, is made sure about by the spine, or spinal section. The ribs structure a confine that shields the heart and lungs, and the pelvis secures the bladder, some portion of the digestion tracts, and in women, the reproductive organs.

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
