Answer the following question given this paragraph: A chemical reaction is a process that changes some chemical substances into others. It involves breaking and forming chemical bonds. Types of chemical reactions include synthesis reactions and decomposition reactions. Q: What is the name of the process that changes some chemical substances into others? A:

A: chemical reaction

Answer the following question given this paragraph: These brilliant red "feathers" are actually animals called tube worms. They live in an extreme environment on the deep ocean floor, thousands of meters below the water's surface. Their world is always very cold and completely dark. Without sunlight, photosynthesis is not possible. So what do organisms eat at these depths? Tube worms depend on chemosynthetic microorganisms that live inside them for food. In this and other ways, tube worms have adapted to the extreme conditions of their environment. Q: What do tube worms rely on for food? A:
OPTIONS:
- fatty microorganisms
- lentiviruses microorganisms
- sponges microorganisms
- chemosynthetic microorganisms
chemosynthetic microorganisms

Answer the following question given this paragraph: How Hormones Work Hormones cause changes in target cells by binding to specific cell-surface or intracellular hormone receptors, molecules embedded in the cell membrane or floating in the cytoplasm with a binding site that matches a binding site on the hormone molecule. In this way, even though hormones circulate throughout the body and come into contact with many different cell types, they only affect cells that possess the necessary receptors. Receptors for a specific hormone may be found on or in many different cells or may be limited to a small number of specialized cells. For example, thyroid hormones act on many different tissue types, stimulating metabolic activity throughout the body. Cells can have many receptors for the. Q: Although what biochemicals circulate throughout the body and come into contact with many different cell types, they only affect cells that possess the necessary receptors? A:
OPTIONS:
- Cells
- organs
- enzymes
- hormones

Answer: hormones

Question: Answer the following question given this paragraph: Flatworms reproduce sexually. In most species, the same individuals produce both eggs and sperm. After fertilization occurs, the fertilized eggs pass out of the adult's body and hatch into larvae. There may be several different larval stages. The final larval stage develops into the adult form, and the life cycle repeats. Q: Flatworms reproduce sexually. in most species, the same individuals produce both what? A:
OPTIONS:
- gametes
- heart and sperm
- diploid and haploid
- eggs and sperm
Answer: eggs and sperm

input: OPTIONS:
- sheath
- annulata
- soleus
- sarcolemma Now, answer this question: 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:
A:
output:
sarcolemma
