D)hemopoiesis. E)regulation of certain electrolytes. Feedback: Correct! 2 CORRECT The skull bones are classified as ________________ bones. A)long B)irregular C)short D)flat Feedback: Correct!
3. Describe the location, composition, and function of the epiphyseal plate. The epiphyseal plate is a layer of hyaline cartilage that allows the bone to grow in length. It is located in the Metaphysis of the growing bone. When the bone is finished growing, the hyaline cartilage is turned into osseous tissue.
Cells are also capable of communication (hormones from endocrine gland cells & neurotransmitters from nerve cells binding to receptors) & defence (proteins – antibodies, bind to harmful substances – antigens & carry out actions to make them harmless. 2. Describe what Protoplasm is. Protoplasm is the living centre of a cell surrounded by plasma membrane. It is the entire substance of the cell.
The stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells. The tissue connecting the lining with the muscular coat is areolar tissue. Describe these three tissues and their roles in the functioning of the
This plate is a layer of hyaline cartilage that allows the diaphysis of the bone to grow in length but not in width. • Articular cartilage is a thin layer of hyaline cartlage covering the epiphysis where the bone forms a joint with another bone. This
The functional and anatomical unit of the spongy bone is the trabecula. Trabecula gives the structured look of the sponge, thus leaving space between for red bone marrow and providing greater surface area. The red bone marrow in the spongy bone is where hematopoiesis, or the production of new blood cells, takes place. 5) The femur would be formed by endochondral ossification.
D) the absence of charged molecules inside cells. Answer: C Page Ref: Section 3 11) The ________ pressure is the pressure required to prevent the flow of solvent through a solvent-permeable membrane that separates two solutions of different solute concentration. A) hydrostatic B) electromotive Answer: C Page Ref: Section 3 12 C) osmotic D) partial 12) Which is true about the solubility of electrolytes in water? A) They are all insoluble in water. B) They are usually only sparingly soluble in water.
Cholesterol also makes the membrane less fluid by restraining the movement of phospholipids and lowers the temperature required to solidify the membrane. Complete depletion of cholesterol and sphingolipids results in cell death as their presence allows permeability to small molecules such as ions, glucose, and water. How does temperature affect lipid membrane? A membrane remains fluid as the temperature decreases, until it solidifies once it hits a critical temperature. The temperature at which a membrane solidifies depends on its fatty acid composition.
