5 Multiple choice questions

  1. 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)
  2. Line the body tracts open to the environment
    ---respiratory , digestive, urinary and reproductive
    ---mucus keeps the living epithelium we and provides lubrication in the digestive tract
    ---traps dust and bacteria in the respiratory tract
  3. A solution with a higher salt concentration than in the cells
    (cells shrink) LESS WATER THAN IN CELL
  4. 1. Blood- plasma, RBC, WBC and platelets
    2. Areolar- Subcutaneous. Connects skin to muscles. Mucous membranes
    3. Adipose- Subcutaneous. Sores excess energy in fat. (insulation)
    4. Fibrous- Tendons and ligaments and dermis of skin (strong)
    5. Elastic- Walls of large arteries and alveoli in lungs (promotes normal exhalation and helps maintain blood pressure)
    6. Bone- Support the body, protect internal organs, store calcium and contain and protect red bone marrow
    7. Cartilage- Wall of trachea to keep airway open, on joint surfaces to prevent friction, tips of nose and outer ears. Absorbs shock between vertebrae
  5. Catalyst: speed up reactions without the use of external energy or heat

5 True/False questions

  1. Describe a covalent bond?Covalent bonds share electrons between atoms
    (ex: H20 or water)

          

  2. What is meiosis?`process of cell division that results in the formation of gametes which are egg and sperm cells.
    (used for creating human life)

          

  3. What are the serous membranes and where they are located?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

          

  4. What are the two types of epithelial membranes?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)

          

  5. What is the cell membrane made up of and what is its function?Nucleus is within the cytoplasm and has a nuclear membrane with nucleoli and chromosomes of the cell. Nucleolus is where DNA and all genetic info for human traits lies.
