B.) ATP comprises a 5-carbon sugar, three phosphate groups, and an adenine base. Energy is released upon breaking the bond between the second and third phosphate groups.
A) in a coil, connected through hydrogen bonds.
The independent variable in an experiment is the one that is deliberately modified or adjusted in order to observe its effects.
In this case, the varying amounts of caffeine administered to the dogs are the factor that changes—the control group receives no caffeine, the second group gets 10 mg of caffeine, while the third group gets 50 mg of caffeine each.
Thus, the amount of caffeine given to the dogs is the independent variable being altered.
Answer:
Exocrine glands are characterized by discharging their secretions into duct systems.
Explanation:
Exocrine glands:
These glands transport their secretions through a network of ducts that ultimately connect to the body's exterior. This means there is a direct continuity between the interior surfaces of the glands and their duct system with the external surfaces of the body (like the skin).
Examples of exocrine glands include gastric glands, salivary glands, and sweat glands.
