Final answer:
A steer with a low specific gravity reading would be leaner, as this suggests less fat tissue, which has lower density compared to muscle and water.
Step-by-step explanation:
The correct answer is option low specific gravity reading. Specific gravity is a measure of the relative density of a substance compared to the density of water. A steer with a low specific gravity would be leaner, as this indicates a lower amount of fat tissue, which is less dense than muscle or water.
Fat tissue has a lower density than muscle tissue and water, thus if a steer's body composition had more fat, its specific gravity measurement would be higher. Conversely, more muscle and less fat would result in a lower specific gravity measurement because muscle is denser than fat.
The correct answer is option a steer with a high specific gravity reading would be leaner. Specific gravity is the ratio of the object's density to the density of water.
A high specific gravity reading indicates that the object is denser than water, which means it has a higher mass per unit volume. In the context of a steer, a high specific gravity reading would suggest that it has a higher proportion of muscle mass, making it leaner.
