Skate park is a good example that maintains the law of conservation as skater neither creates nor destroys energy.
Explanation:
As per the law of energy conservation, energy cannot be created nor can be destroyed but it’s form can definitely be changed. This theory can be well justified by the example of skate park playground. According to the rules of this law a skater can never go high more than 2 meters on the ramp’s other side because it has that gravitational energy potential.
With every drop of the skater on the ramp the potential energy of the skater changes into kinetic energy. This two sides of the law justifies the fact that skate playground should be designed in such a way that it supports the law of conservation of energy.
Answer:
giraffes necks consists a tall bone like structure called notochord which gives support to the skeletal system like how do we have backbone
It would be the endocrine system
Answer:
option B
Explanation:
The correct answer is option B
Cells are the basic structural and functional unit of life and possess genes. These genes evolve to carry out new biological functions in the body.
Cells undergo division and growth whether it be unicellular organisms or multi cellular organisms.
All cells possess the property of compartmentalization and metabolism henceforth taking up nutritive material from the environment.
These nutrients are further transformed into the cell compartments and the waste produced as a result is expelled out thus forming on open system.
