<span>D.Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). This is because cells respire constantly, as this process uses up oxygen cells will contain less oxygen than its surroundings. Oxygen moves by the process of diffusion, in diffusion a molecule will always move from a higher concentration to a lower concentration.</span>
bones, ligaments, tendons and joints hope this helps! :)
Answer:
Patches of fibrocartilage formed in the healing of a fracture are called <u>soft callus</u>, whereas the bony collar formed around the fracture is called <u>hard callus</u>.
Explanation:
In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
The order of the vessels in which the blood will pass through is
right internal jugural vein
right brachiocephalic vein
superior vena cava
cavernous sinus
aorta
brachiocephalic trunk
cebebral arterial circle
right common carotid artery
The blood flows through the veins, the heart, and the arteries.
Answer:
D) Cell - Tissue - Organ - Organ system
Explanation:
Cell organization starting from cell to organ system shows the relationship among different levels of cell organization. The cell organization helps to know the structural and function of the organisms.
The correct order of cell organization:
Cell – tissue - organ - organ system
Different organsystems organise to for an organism. The cell is the simplest level and a group of cells (tissue) is the next higher level, a group of a tissues (organ) and a group of organs makes organ system which is the complex level of organization.
