Answer: E. A B, and C only
Explanation:
An exoskeleton is a hard, rigid, protective external structure that supports and protects the body of the animal from the damage caused either by injury or by predator. It supports and protects the inner organs and structures, acts as a barrier against desiccation. These act as a point of attachment of the muscles which provides a structural framework to the body. The exoskeleton is waterproof hence, protects the organism from being affected by the external water. It can be seen in the form of shells or scales, nails, hooves and other structures.
Answer:
Hi there!
Your answer is:
Dependent variable: Plant growth
Independent variable: Day length
Explanation:
The independent variable is Intentionally manipulated by the researchers. We know exactly what it will be each day, because we control it! Since the scientists are controlling the day length, that is your independent variable.
The dependent variable is NOT manipulated by the researchers. We are studying what the dependent variable does in reaction to the changing independent variable. Since we are recording & studying how the plant grows based on the day length, that is your dependent variable!
I hope this helps!
