Introduction Understanding the relationship between form and function in organisms can increase our knowledge about natural processes, especially when it comes to investigating how physical laws apply to the adaptive design of organisms. The mode of locomotion plays a major role in the evolution of many body traits. Most terrestrial organisms walk or run upright on horizontal surfaces. Organisms that climb on vertical surfaces or hang from objects most likely evolved, through natural selection, specialized modes of locomotion to optimize ease and rate of movement.

In order to move, animals need to "build up" energy and then use that energy in a controlled way. One way to do that is through the interchange of kinetic and gravitational potential energy. One method to do this is an animal moving forward over a stiffened leg. In the initial part of the cycle, some of the kinetic energy used to propel the animal forward also raises its center of mass, increasing its gravitational potential energy. As the center of mass falls, gravitational potential energy is converted back into kinetic energy which facilitates the next step. This is called the inverted pendulum model (Figure 1).

What is the basic question of this study and why might it be an interesting and relevant topic for scientists to study?

explanation:

its math

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
