What is the analysis of body systems that we can see?
Gross anatomy
What is a level of variable that the cell can handle?
Set point
What organelles that do not connect to other organelles are responsible for synthesizing proteins?
Free ribosomes
What is the normal state of a living cell?
Interphase
What can easily get through the phospholipid bilayer?
Water and small water-soluble molecules (via channel proteins)
fatty substances
Small ions
What is the study of how body parts function and work together to make the body work?
Physiology
Which organ system exchanges oxygen and carbon dioxide between the blood and the air?
What is the fluid part of the cytoplasm?
Cytosol
What is the unwinding of a DNA molecule to make a copy of an individual DNA molecule?
What part of the phospholipid bilayer is responsible for allowing cells to identifying each other?
Glycoproteins
What is the function of the urinary system?
Removing waste from the blood, regulating blood pH, water balance, and ion balance
How does a cell maintain homeostasis
Doing the opposite of a stress
What do lysosomes do?
Break down lipids, proteins, sugars, nucleic acids, and carbs
Between passive transport and active transport, which one requires energy?
Active transport
What is the function of the integumentary system?
Protecting the body, regulating body temperature, preventing water loss, and producing Vitamin D.
What is surface anatomy used for?
What is a control center?
The part of the body that receives information about a variable, determines the set point, and signals a response to correct imbalances
What is the difference between chromatin and chromosomes?
Chromatin - spread DNA in the nucleus
Chromosomes - bundles of DNA formed during cellular reproduction
What is phagocytosis?
Cells ingesting particles
What is the difference between tRNA and mRNA.
mRNA - the copy of the individual part of DNA. is able to leave the nucleus
tRNA - brings the correct amino acid to the ribosome to make the protein
Human development from conception to eight weeks old
Receptor detects a decrease in the variable
Control center responds by sending a message to one or more effectors
Effectors that receive the message alter their activities
The variables increase in response to the activity of the effectors
The polar ends of the phospholipids are attracted to each other. So, even if somethin happens, it can easily form back together.
List and describe the four steps of cellular reproduction.
Prophase - centrioles duplicate and move toward the end of the cells. chromosomes form towards the center
Metaphase - the spindle fibers start to pull on the chromosomes
Anaphase - the duplicates and original DNA separate and are pulled to opposite ends of the cell
Telophase - the plasma membrane constricts to pinch a cell in two
What is the function of the smooth ER? Rough ER?
Smooth ER - Intracellular transport and production of lipids and carbs
Rough ER - intracellular transport and protein synthesis/movement
Label the following parts of a cell: mitochondrion, secretory vesicle, plasma membrane, nuclear pore, nuclear envelope, ribosome, intermediate filament, smooth ER, rough ER, microtubule, centriole, lysosome, Golgi apparatus, chromatin, nucleolus, cilia, and microtubule
