Answer:
True
Explanation:
In phase-contrast objective and a phase contrast optical systems is equipped with Light microscope .
Phase contrast microscope is used to differentiate unstained structures in a cell that differ in refractive indices and thickness. Thus it is usefull for examining living unstained organisms.
Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.
Hoping this might help!!!
It is Chemistry.
Cu+AgNO3=Ag+Cu(NO3)2
==>
Cu+2AgNO3=2Ag+Cu(NO3)2
Answer:
The Gestalt Principles are a set of laws arising from 1920s’ psychology, describing how humans typically see objects by grouping similar elements, recognizing patterns and simplifying complex images. Designers use these to engage users via powerful -yet natural- “tricks” of perspective and best practice design standards.
Explanation:
<span>Fish have adaptable behaviors and structures so that they can
survive in the wild. These adaptations however differ with regards to context
and environment. Some fishes for example are called stonefish because they can
camouflage in environments that are composed variedly with pebbles and rocks,
and this helps them to avoid predators and thrive. Nevertheless, when these
group of organisms are strayed and become exposed to a new environment they can
be exposed and be vulnerable to predators. </span>
Answer:
Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.
Everyday life examples:
(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.
(2) Tubes of bicycles are filled by the pumps that compress the air.
(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.
4) oxygen bottles in medical institutes for helping the patient to breathe.
