Some helpful tips:
The nucleus is always going to be the big, spherical shape.
The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)
The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.
The mitochondria is always going to be pill-shaped and have weird folds inside of it.
Answer:
Combined decrease in sarcomere length.
Explanation:
Sarcomere is the functional unit of the striated muscle tissue. The units get repeated between the two Z lines. The striation under the microscope is shown by the sarcomere.
Actin and myosin protein plays an important role in the muscle contraction. The individual length of the thick (myosin) and thin (actin) filament do not changes and slide over one other. But the sarcomere overall length decreases that result in muscle contraction.
Thus, the answer is combined decrease in sarcomere length.
Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.
B. The products of the electron transport chain are H2O and either NAD or FAD.
E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.
Explanation:
the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
