Explanation:
A vector is a
quantity that has both magnitude and direction and to identify the components
of vector, you need to break it into parts called components. These components depict
the influence of that vector in a given direction. For example, in the vector
(6, 2), the horizontal or x-axis component is 6 and the vertical or y-axis
component is 2. With this, you have an angle and a magnitude to define a
vector, where you have to find the components yourself with the help of
trigonometry. The magnitude of vector is expressed as v and by multiplying both
sides of these equations by v, you can expressed the x and y components as Vx = vcos and Vy = vsin.
The combined
influence of the two components is equivalent to the influence of the single
two-dimensional vector and this single two-dimensional vector could be replaced
by the two components.
A map is a diagrammatic representation of an area of land or sea showing physical features, cities, roads, etc.
Answer:
Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.
Explanation:
- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.
- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.
- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.
- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.
N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.
- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.
- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.
