The smallest unit capable of life on its own is a(n)?
What is the name for the process where small, uncharged, molecules such as CO2 and O2 are able to move from areas of high concentration to low concentration across a semi-permeable membrane?
Diffusion or Passive diffusion.
Use at least 3 directional and / or regional terms to describe the location of the wound I (the teacher) points to.
answers vary.
What is an Isotonic solution?
A solution with equal amounts of dissolved stuff on both sides of a membrane. Cell will stay the same size.
Explain Endocytosis
the engulfing of large molecules by the cell "eating" things through pinching off pieces of the membrane. Requires energy making it an active process.
Organize the parts below from most basic to most complex according to the levels of organization in a multicellular organism.
A. human being -> central nervous system -> brain -> nerve tissue -> neurons
B. neurons -> brain -> nerve tissue -> central nervous system ->human being
C. neurons -> nerve tissue -> brain -> central nervous system -> human being
D. nerve tissue -> central nervous system -> neurons -> brain -> human being
C
Which process would be used to move Very Large molecules through the cell membrane without using energy?
Facilitated diffusion
chest
Which type of solution will cause a cell to swell?
Isotonic, Hypertonic, or Hypotonic
Hypotonic. It has more water than inside the cell, so water moves into the cell.
Give an example of a Signal -> Effector -> Response cycle.
signal: hand touches hot stove
Effector: nerve feels pain and sends response to muscle tissue
Response: muscle tissue pulls hand back.
Inherited traits are passed down from our parents to us, their offspring, by the information that is coded in our parents' _____________?
Chromosomes / DNA
What is homeostasis?
The body's ability to maintain a stable state.
Which type of muscle cell would have striations (bands) and you can control voluntarily?
Skeletal muscle
Which type of solution will cause a cell to shrivel?
Isotonic, Hypertonic, or Hypotonic?
Hypertonic. Less water on outside causes water to leave the cell.
touch your proximal antebrachial region.
heh, simon didn't say.
If a cell failed to go through DNA replication prior to mitosis, what would be the resulting issue with the daughter cell?
The daughter cells would not have the correct number of chromosomes and would unfortunately die. It would have too few chromosomes.
Describe the difference between how negative and positie feedback loops help to maintain homeostasis.
Negative feedback brings you back to a neutral point (temperature, glucose)
Positive feedback causes a chain reaction that makes the process continue even more. (breast feeding makes more milk)
many layered, column shaped cells are called what?
stratified columnar
Which type of tissue is responsible for body movements?
Muscle tissue
What vocabulary term would be used in reference to an external rash on the most outer layer of skin?
Superficial
Explain the structure of the cell membrane and draw it on the board. Include the two macromolecules that are embeded within it, the polarity of the different parts of the membrane, and why this makes the membrane selectively permeable.
The body system responsible for the secretion of hormones inside the body is called the...
Endocrine system
To treat the rash he was given, Daniel was given a steroid shot just inferior to his glutes.
Did he have to take off his shirt or his pants to receive this shot?
Pants!
Skeletal muscle is composed of very hardworking cells. Which organelles would you expect to find in abundance in a skeletal muscle cell?
A. mitochondria B. nuclei C. ribosomes D. vacuoles
A. Mitochondria
Salivary gland cells often specialize in packaging and secreting digestive enzymes in vesicles. Which organelle do these cells most likely have in abundance to aid in accomplishing this task?
Lysosomes
