Hmmm im reallt not sure this pretty hard im stuck i need help!
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
I believe that it's an exhausted bear. Cellular respiration is the way plants and animals receive energy. If the bear is exhausted, it means it's cellular respiration is lacking.
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
