Answer:
Egg is HYPERTONIC
Water in the bowl is HYPOTONIC
The egg will become filled with water over time
Explanation:
Tonicity refers to the ability of an extracellular solution to direct the flow of a solvent (water) in and out a cell. There are three types of tonicity; hypertonic, hypotonic and isotonic. A solution is said to be HYPERTONIC when the concentration of solute in it is higher than its external solution. This is the case of the egg cell that contains 7% salt (solute).
A HYPOTONIC solution is that which contains a lower solute concentration than it's external solution. This is the case of the water in the bowl that contains 3% salt concentration.
Tonicity determines which direction osmosis occurs. Osmosis is the movement of solvent/water from a region of high solvent concentration/low solute to a region of low solvent concentration/high solute concentration via a semi-permeable membrane. In this case, water (solvent) will move through the egg cell membrane (semi-permeable membrane) from the bowl with a low solute concentration into the egg with a high solute concentration. Hence, over time, the egg cell will be filled with water.
B. usually contains a large amount of matrix
<u>Answer:</u>
You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction
<u>Explanation:</u>
Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.
Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
The correct option is A.
Proactive interference refers to the tendency of the knowledge that one had learned previously to prevent one from subsequent learning. Thus, proactive interference is the difficulty that comes with learning new things due to the stuffs that one had learned before. For instance, an individual may find it difficult to learn Spanish because he has previously learn German.<span />
