Question

define :
1. cellular respiration
2;. rectilinear propagation of light
3. photosynthesis
4. fertilization
5. joule's law of heating affect

Answer 1

Answer:

3/photosynthasis is the best answer

Answer 2

1. Cellular respiration is a series of metabolic processes taking place in a cell . It converts chemical energy from nutrients into adenosine triphosphate(ATP), and then release waste products.
2. Rectilinear propagation describes the tendency of electromagnetic waves (light) to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.
3. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
4. The fusion of the male gamete (sperm) and female gamete (ovum) is called fertilization.
5. When an electric current passes through a conductor for some time, the conductor gets heated up. Thus heating of a conductor due to the flow of electric current through it is known as Joule's law of heating.
