Your question was.... "What layer of the blood vessel wall is composed of areolar connective tissue containing elastic and collagen fibers"
Your answer is the Tunica intima, Because, The blood vessel's tough outer layer is made up of connective tissue, which permits it to withstand stresses occurring on the vessel wall. It also contains strong collagen fibers that help bind the blood vessel to surrounding tissues, providing stability to the vessel.
I really hope this helps! :)
The answer is water, oxygen, and chemical energy are required, and ATP is changed to ADP.
Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen using the energy of sunlight. Sunlight energy is converted into chemical energy stored in carbohydrates. For this process, ATP is used and, thus, changed to ADP.
Answer:
Medullary cavity, epiphyses
Explanation:
During the thickening of the bone collar, the penetration of Osteoblasts into the decomposing cartilage occurs thereby replacing it with spongy bone giving rise to a primary ossification center.
Osteoclasts then brings abiut the nreak down of the spongy bone to open up the medullary cavity. The cartilage found in the epiphyses then continue to grow increasing the bone's length.
