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.
Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
The periodic table only accounts for elements. It does not account for compounds, such as water.
<span>The answer is the option a. Filter feeders - strain food from water. You can realize the the option b is no rirght because carnivores eat meat (other aninals), c is not rigth because paraistes do not help other animals but they harm other animals, and d. is not right because herbivores eat plants and not bits of decaying matter. So you can eliminate b, c, and d. While a. reflects exactly what filter feeders eat.</span>
The function of each protein molecule depends on its shape, which in turn is determined by the protein specific sequence of AMINO ACIDS.
Proteins are a type of macro molecules that are made from amino acids, each protein is a long chain of different amino acids. There are twenty different amino acids in existence. Protein carry out several crucial functions in the cells of living organisms. The specific functions which a protein carries out is determined by its shape and the three dimensional structure of the protein. The shape of the protein depend on the type of amino acids that made up the protein. <span />
