- Where is genetic coding found?
- What is filtration and how does it work?
- What are the two types of epithelial membranes?
- What is mitosis?
- What is diffusion and how does it work?
- a Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
- b movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
(Example: exchange of gases in lungs or body tissues)
- c Requires energy of mechanical pressure. Water and dissolved materials are FORCED through a membrane from an area of higher PRESSURE to an area of lower PRESSURE
(Example: formation of tissue fluid and the first step in the formation of urine)
- d Serous membranes: line some closed body cavities and cover the organs in those cavities (thoracic and abdominal cavities) CAVITIES THAT AREN'T OPEN TO AIR
Mucous Membranes: line the body tracts that have openings to the environment and have a mucous membrane to keep the lining of the cells wet (vagina, trachea, esophagus and stomach)
- e In the DNA of our chromosomes or our genome. It is found in the cell nucleus.
5 Multiple Choice Questions
- ER or endoplasmic reticulum- are tubules that transport materials necessary for cell function within the cell.
Ribosomes- are very small structures made of protein and ribosomal RNA and are found on the surface of rough ER.
Proteasome- is a barrel shaped organelle made of enzymes that cut protein molecules apart.
Golgi apparatus- are flat, membranous sacs where carbohydrates are synthesized and are packed with other materials for cellular secretion.
Mitochondria- are oval organelles bound by a double membrane where cell respiration takes place and site of ATP production.
Lysosomes- are single membrane structures that contain digestive enzymes and eat dead cells and bacteria .
Centrioles- are a pair of rod shaped structures outside the nucleus that spindle fibers during cell division.
Cilia and Flagella- are thread-like projections through the cell membrane that can sweep materials across cell surface and flagellum provide mobility of the cell.
Microvilli- are folds of the cell membrane that increase surface area of membrane when needed. They are good for absorption of nutrients as well.
Cytoskeleton- are the framework and support of the cell. Made of microfiliaments.
- 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
- Standing with legs shoulder width apart, arms down by side with palms forward
- Serous membranes are in closed body cavities where the serous fluid prevents friction between the two layers of the serous membrane.
---Thoracic cavity: partial pleura lines chest wall and cisceral pleura covers the lungs.
---Pericardial sac: parietal pericardium lines the fibrous pericardium and the visceral pericardium covers the heart muscle.
---Abdominal cavity: peritoneum lines the abdominal cavity and mesentary covers the abdominal organs
5 True/False Questions
Name some ways the body uses homeostasis? → ability of the body to maintain a relatively stable metabolism and to function normally despite changes
What is contained in the spinal cavity? → Spinal vertebre
Point out cell organelles and name →
What is isotonic? → A solution with lower salt concentration than in the cells
(cells burst) MORE WATER THAN IN CELL
Describe a Hydrogen bond? → does not involve the sharing of electrons but results in hydrogen atoms
(ex: water molecules are attracted to nearby water molecules to form surface tension)
