Tissue groups of cells that are similar in structure and perform a common or related function Four primary tissue types epithelial -- covering Connective -- support Muscle -- movement Nervous -- control Histology study of tissues Epithelial tissue or epithelium sheet of cells that covers a body s...

Types and locations of connective tissues associated with skeletal muscle. *Endomysium- thin connective tissue that surrounds each individual muscle cell (fiber) *Perimysium- Connective tissue that bundles muscle cells (between 10-100) into a fascicle. *Epimysium- Outer fibrous connective tissue w...

Patterns of Darwinian Evolution change over time, change over geographic distance, resemblance to fossils, homology, vestigial traits Processes of Darwinian Evolution Descent with modification (evolution happens to populations, not individuals), natural selection (sorting process) Under the theory...

Equation of how Enzymes function in reaction Substrate(s) + Enzyme = Product(s) + Enzyme What is the optimal temperature for most enzymes to work at? 37 degrees Celsius What happens when temperature is too high for an enzyme? Enzymes can unfold and lose their 3D shape. What pH do cytosolic enzyme...

Groups of cells that are similar in structure and perform a common or related function are called Tissues These basic tissues are epithelial, connective, muscle and nervous General role for each tissue type are covering-epithelial Support-Connective Movement-Muscle Control-Nervous The studio of t...

When a plant is alive it has energy in its living parts. When it dies all the parts are still there, but it is no longer alive. How much of the energy is still in the dead (but not yet decomposing) plant? Nearly all of the energy Where does most of the matter in a plant come from? gas in the air W...
