Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
Answer:
When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).
Explanation:
A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.
<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.
