Answer the following question given this paragraph: Skeletal Muscle Fiber Structure Each skeletal muscle fiber is a skeletal muscle cell. These cells are incredibly large, with diameters of up to 100 m and lengths of up to 30 cm. The plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma is the site of action potential conduction, which triggers muscle contraction. Within each muscle fiber are myofibrilslong cylindrical structures that lie parallel to the muscle fiber. Myofibrils run the entire length of the muscle fiber, and because they are only approximately 1.2 m in diameter, hundreds to thousands can be found inside one muscle fiber. They attach to the sarcolemma at their ends, so that as myofibrils shorten, the entire muscle cell contracts (Figure 38.34). Q: The plasma membrane of a skeletal muscle fiber is called the what? A:

OPTIONS:
- sheath
- annulata
- soleus
- sarcolemma

Answer: sarcolemma

Problem: OPTIONS:
- bicellular sphincters
- diocesan sphincters
- cell membrane
- precapillary sphincters
Q: Answer the following question given this paragraph: Q: What regulates the passage of blood into capillary beds? A:
Answer: precapillary sphincters

Problem:OPTIONS:
- storms
- floods
- snowfall
- eruptions

Answer the following question given this paragraph: Scientists measure the gases that escape from a volcano to predict eruptions. Gases like sulfur dioxide (SO 2 ), carbon dioxide (CO 2 ), hydrochloric acid (HCl), and water vapor can be measured at the site. Gases may also be measured from satellites. The amounts of gases and the ratios of gases are calculated to help predict eruptions. Q: Scientists measure the gases that escape from a volcano to predict what? A:
****
A: eruptions

Answer the following question given this paragraph: Two separate membranes form the mitochondrion. The inner membrane folds into cristae which divide the organelle into three compartments: the intermembrane space (between outer and inner membranes), cristae space (formed by infoldings of the inner membrane), and the matrix (within the inner membrane). The Krebs Cycle takes place within the matrix. The compartments are critical for the electron transport chain structure and function. Glycolysis occurs in the cytoplasm of the cell, with the products of glycolysis entering the mitochondria to continue cellular respiration. Q: How many membranes form the mitochondrion structure of a cell? A:
OPTIONS:
- one
- five
- three
- two
two

Answer the following question given this paragraph: The charge on a single electron is and is known as the elementary charge. Q: What is the charge on a single electron known as? A:

Answer:
elementary charge
