Answer:
Epidermal cells secrete the waxy hydrophobic substance cutin that polymerizes on the surface, forming a barrier to water evaporation. Epidermal cells are transparent because their plastids remain small and undifferentiated; hence light readily penetrates through to the photosynthetic tissues beneath the epidermis.

Answer:
in the Air sacs
Explanation:
the air sacs has a million tiny holes and that is probably where oxygen transfers

Answer:
Five (5)
Explanation:
A <u>total of five (5) paramecia </u>can be accommodated within the FOV.
The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.
<em>If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:</em>
100/20 = 5 paramecia
