1. Exercise develops physical fitness.
2. Range of motion is how far any body part can move in any direction.
3. Muscle myofibrils are made of both thick and thin filaments. These filaments are the used in muscle contractions. The thick filaments and thin filaments slide along each other during a muscle contraction.
4. Lactic acid is removed from muscles when there is an increased amount of blood flow (usually during exercise).
5. Posture is the way a person holds their body when sitting or standing.
6. Varicose veins occur when the veins are weakened and become twisted over time. Normal veins will flow in one direction and there is no back flow because of the valves. When veins are weakened and the valves don’t work properly, the blood can collect in your legs.
7. Antagonistic muscles pair with agonist muscles (best example is the bicep-tricep pair). This means that as one muscle contracts, the other will relax.
Answer:C) To choose the trail that will provide the best experience, there are many elements to consider.

Hello. This question is incomplete. The full question is:
Kalani and lael are students who have been comparing the total kinetic energy of an iceberg to an ice cube
Kalani’s Argument: My claim is that an iceberg has more total kinetic energy (thermal energy) than an ice cube. This is because even though an iceberg is about the same temperature as an ice cube, it is also much larger, so it is made of a lot more molecules. For this reason, an iceberg will have more total kinetic energy (thermal energy) than an ice cube.
Lael's Argument: An iceberg has more total kinetic energy (thermal energy) than an ice cube because it is larger and made of more molecules. This matters because molecules move, and moving things have kinetic energy, so each molecule adds its kinetic energy to the total. Since the iceberg and the ice cube are around the same temperature, the fact that the iceberg has extra molecules means that it will have more total kinetic energy (thermal energy).
Which argument is more convincing?
Answer:
Kalani's argument is more convincing.
Explanation:
Lael says that the fact that Icebrg has extra molecules means that it has greater kinetic energy and this is not true, since the kinetic energy is greater in bodies and objects that have greater speed. In addition, speed increases as a body has greater mass. In this case, we can consider Kalani's argument as more convincing, since she related the kinetic energy to the mass of the iceberg.
