Ques:Q: What class of acids do carboxylic acids fall under? Read this paragraph and choose the correct option from the provided answers: Common acids and the polyatomic anions derived from them have their own names and rules for nomenclature. The nomenclature of acids differentiates between oxoacids, in which the H+ ion is attached to an oxygen atom of a polyatomic ion, and acids in which the H + ion is attached to another element. Carboxylic acids are an important class of organic acids. Ammonia is an important base, as are its organic derivatives, the amines. Choices: - hydrochloric acids - inorganic acids - carbolic acids - organic acids A:

Ans:organic acids

Ques:Q: Skeletal, cardiac, and smooth are the three types of what cells and possess morphologies correlated with their functions? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - cartilage tissue - organ - bone - muscle A:

Ans:muscle
