The skeletal system of a human body gives form, shape, and structure of the body. These includes all the bones and all the joints with each bone being a complex organ itself.
The skeletal system has two divisions: (1) axial and (2) appendicular. All the vertical 80 axial bones comprised the vertical axis of the body while the 128 including free appendages consist the second division.
The answer to the question above based on the description given is AXIAL.
One sperm fertilizes the egg cell forming a diploid zygote, the other sperm fuses with the two polar nuclei forming a triploid cell that develops into endosperm
Photosynthesis produces oxygen and water. Photosynthesis is the result of a cycle. Humans use oxygen for respiration, the product produced from human respiration is carbon dioxide. Then plants absorb carbon dioxide from the air and turn it into oxygen with photosynthesis, this goes on and on as a cycle.
