Answer the following question given this paragraph: 4.4 Muscle Tissue and Motion The three types of muscle cells are skeletal, cardiac, and smooth. Their morphologies match their specific functions in the body. Skeletal muscle is voluntary and responds to conscious stimuli. The cells are striated and multinucleated appearing as long, unbranched cylinders. Cardiac muscle is involuntary and found only in the heart. Each cell is striated with a single nucleus and they attach to one another to form long fibers. Cells are attached to one another at intercalated disks. The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm. Q: Skeletal, cardiac, and smooth are the three types of what cells and possess morphologies correlated with their functions? Choices: - cartilage tissue - organ - bone - muscle A:
**Answer**
muscle
Answer the following question given this paragraph: Section Summary 1.1 Physics: An Introduction Science seeks to discover and describe the underlying order and simplicity in nature. Physics is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions. Scientific laws and theories express the general truths of nature and the body of knowledge they encompass. These laws of nature are rules that all natural processes appear to follow. Q: Is the most basic what is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions? Choices: - experiments - biology - genetics - physics A:
