Question

1. describe two properties of water and explain how they are important to living organisms.
2. how does capillary action help plants survive?
3. why is the scientific method important in biology?

Explanation:

Question 3:

Water has high heat - capacity. This property allows water to absorb and store a large amount of heat without a significant temperature change, which helps organisms maintain a stable internal temperature. Water also has cohesion. Cohesion enables water molecules to stick together, which is important for processes like transpiration in plants and blood circulation in animals.

Question 4:

Capillary action in plants occurs due to the combination of adhesion (water sticking to the walls of xylem vessels) and cohesion (water molecules sticking to each other). It helps plants transport water and nutrients from the roots to the leaves against gravity, which is essential for photosynthesis and overall plant survival.

Question 5:

The scientific method is important in biology as it provides a systematic and objective way to test hypotheses, gather evidence, and draw conclusions. It helps ensure that biological research is reliable, reproducible, and can lead to the discovery of new knowledge about living organisms and their processes.

Answer:

Question 3:

High heat - capacity: Maintains stable internal temperature. Cohesion: Aids in biological transport processes.

Question 4:

Transports water and nutrients from roots to leaves against gravity.

Question 5:

Provides a systematic and objective research approach for reliable and reproducible results.
