<h2>Answer:</h2>
False
<h2>Explanation:</h2>
Water is perhaps the most important component of any ecosystem. All living organisms need water to grow and survive. The organisms involved in this cycle are plants, animals, bacteria and decomposers. All of them use water for their own processes and functions. The processes involved are evaporation, condensation, sublimation, precipitation, transpiration, runoff, and infiltration. Since plants and animals both need water in very greater amount therefore we cannot neglect their importance in water cycle.
<u>Answer:</u>
Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.
<u>Explanation:</u>
- One of the major difficult issue related to bird evolution is the evolution of feathers.
- Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
- Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
- Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
The disease is mainly caused by a lack of a slippery substance in the lungs called surfactant. This substance helps the lungs fill with air and keeps the air sacs from deflating. Surfactant is present when the lungs are fully developed.

Answer:
The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
