Question

Why might the evolution of specialized tissues be important for animal function and complexity?

a) It allows for greater energy efficiency.
b) Specialized tissues enable animals to perform more complex tasks.
c) It reduces the need for adaptation.
d) It increases resistance to environmental changes.

Answer 1

Specialized tissues are important for animal function and complexity because they provide greater energy efficiency, enable animals to perform complex tasks, and increase resistance to environmental changes.

Step-by-step explanation:

Specialized tissues are important for animal function and complexity for several reasons:

1. Greater energy efficiency: Specialized tissues allow animals to perform specific tasks more efficiently, leading to reduced energy expenditure. For example, the circulatory system brings nutrients and removes waste, while the respiratory system provides oxygen and removes carbon dioxide.
2. Complex task performance: Specialized tissues enable animals to perform more complex tasks that require coordination between different cells and organs. For example, neural tissues and muscle tissues allow animals to sense and respond rapidly to changes in their environment.
3. Increased resistance to environmental changes: Specialized tissues help animals adapt to their environment and increase their chances of survival. For example, sensory structures help animals navigate their environment and detect food sources, while muscle tissue allows for movement and escape from predators.
