Answer:

The cell has different parts, and those that can absorb stains or dyes are referred to as chromatic. Having absorbed the stain, these parts of the cell become more visible under the microscope and can therefore be easily distinguished from other parts of the same cell.

Without stains, cells would appear to be almost transparent, making it difficult to differentiate its parts.

Explanation:Methylene blue has a string affinity for both DNA and RNA. When it comes in contact with the two, a darker stain is produced and can be viewed under the microscope

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter

Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

Waves are caused by

KiRa [710]

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
