La hipótesis señalan las relaciones o vinculos existentes entre las variables y cuales de ellas se debe estudiar sugiriendo una explicación en ciertos hechos y establecer como se debe organizar el análisis de los datos. Las observaciones es el método para reunir información visual sobre lo que ocurre o como se comporta el objetivo
Method 1:1. Start with your equation and determine which variables you know.
2. Use the lens equation to get d.
3. Sovle for h.
4. Solve for M.
5. Interpret your M value.
6. For diverging lenses, use a negative focal length value.
The correct answer is: A. Myofibrils contain thick and thin filaments.
Skeletal muscle cells are called muscle fibers because of their long and cylindrical shape. The plasma membrane of muscle fibers is sarcolemma, the cytoplasm is sarcoplasm, and the smooth endoplasmic reticulum sarcoplasmic reticulum (SR) Sarcoplasmic reticulum is specialized becaused it is involved in the process of contraction, so it stores, releases, and retrieves calcium ions.
The functional unit of a skeletal muscle fiber is the sarcomere which consists of highly organized contractile myofilaments actin that are thin filaments and myosin (thick filaments), together with other support proteins.
Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.
