Answer:
Option 3 and 4 are most likely correct
Explanation:
<em>Option 3</em>: We know that area 1 would contain heavy streaking and not single colonies. Therefore, if the loop crosses area 3 and enters area 1, it will definitely result in heavy streaking again.
<em>Option 4</em>: We always need to sterilize properly the loop when streaking in different areas. If we don't do it, it is possible that the loop contains a lot of bacteria that would be streaked again.
Options 1 and 2 are incorrect because, according to question, there is a uniform growth but no isolated colonies. So, contamination or mixed culture would not produce uniform growth streaking rather mixed with other bacterial types.
When someone says that I think it means that they feel the ability to move freely without tiring easily.

Here are two Eukaryotic cells Plant and Animal
Answer:
1) A hypotonic solution occurs when the solute concentration outside of the cell is higher than the solute concentration inside the cell.
2) Most cells have an electrical potential difference of between –40 and - 80 millivolts.
3) Osmosis is a determining force in water movement, and causes water to move from areas of high water concentration to low water concentration.
4) In most cells, there are more water molecules inside the cell and more sodium molecules outside the cell.
It depend some plants have the waxy layer because of their cuticles and to make sure the leaf doesn't dry out or to protect it againts the harmful sun rays when directly shined on its good to have sun but not too much. HOPE THIS HELPS
