What is the term for the boundary between vadose water and groundwater?

1 answer:

5 0

The answer is water table. Water table is the boundary between vandose zone and the zone of saturation. The unsaturated is the vandose while the saturated is the groundwater zone. Water table is located in the top of an unconfined aquifer, that can tell the level below which soil and rock are saturated with water and the top of the zone that is saturation.

Answer:

What is the effect of power/magnification on the frequency and size of organelles under a microscope?

Explanation:

Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.

Hypotheses:

organelle A's frequency decreases while B's frequency increases at higher magnifications
organelle A's size increases while B's size decreases at higher magnifications

Dependent variables: size and frequency cell organelles

Independent variable: power/magnification at low (x4), medium(x10) and high (x40)

Controlled variables: Type of organelles, microscope used, cell examined,

Method:

1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.

Frequency: What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.

2. Record and tabulate observations.
