1. Foot or base

It is a U-shaped structure and supports the entire weight of the compound microscope.

2. Pillar

It is a vertical projection. This stands by resting on the base and supports the stage.

3. Arm

The entire microscope is handled by a strong and curved structure known as the arm.

4. Stage

The flat and rectangular plate that is connected to the arm’s lower end is called the stage. The specimen is placed on the stage for studying and examining the various features. The centre of the stage has a hole through which light can pass.

5. Inclination joint

It is a joint, wherein the arm is fastened to the compound microscope’s pillar. The microscope can be tilted using the inclination joint.

6. Clips

The upper part of the stage is connected to two clips. The slide can be held in its position with the help of the clips.

7. Diaphragm

The diaphragm is fastened below the stage. It controls and adjusts the intensity of light that passes into the microscope. The diaphragm can be of two types:

Disc diaphragm

Iris diaphragm

8. Nose piece

The nose piece is circular and a rotating metal part that is connected to the body tube’s lower end. The nose piece has three holes wherein the objective lenses are embedded.

9. Body tube

The upper part of the arm of the microscope comprises a hollow and tubular structure known as the body tube. The body tube can be shifted down and up using the adjustment knobs.

10. Fine adjustment knob

It is the smaller knob, which is used for sharp and fine focusing of the object. For accurate and sharp focusing, this knob can be used.

11. Coarse adjustment knob

It is a large knob that is used for moving the body tube down and up for bringing the object to be examined under exact focus.

1. Eyepiece lens or Ocular

• At the top of the body tube, a lens is planted which is known as the eyepiece. On the rim of the eyepiece, there are certain markings such as 5X, 10X, 15X, etc. These indicate the magnification power. The object’s magnified image can be observed with the help of an eyepiece.

2. Mirror

• A mirror is found attached wither to the pillar or the lower end of the arm. It consists of a concave mirror on one side and a plain mirror on the other side. It can be used for reflection of light rays into the microscope.

3. Objective lenses

• At the bottom of the body tube, there are two objective lenses, which are connected to the revolving nose piece. The three objective lenses are as follows:

Oil immersion objective – 100X

High power objective – 45X

Low power objective – 10X

Answer:

1. B

2. A

3. C

4. D

5. A

Step-by-step explanation:

1. B because an polynomial function is only have non negative exponent or positive exponent as its degree

2.P(x) = (x+4)³ (x-5)⁶

(x+4=0)³

(x=-4)³

-4 multiplicity of 3

(x-5=0)⁶

(x=5)⁶

5 multiplicity of 6

3. just add all exponents to get the highest degree

4. p(x) = 2x³+3x²-4x-24

p(3) = 2(3)³+3(3)²-4(3)-24

p(3) = 2(27)+3(9)-12-24

p(3) = 54 + 27 - 12 - 24

p(3) = 81 - 12 - 24

p(3) = 69 - 24

p(3) = 45

5. p(x)=x³+x²-6x-6

p(x) = (x³+x²) + (-6x-6)

p(x) = x²(x+1) -6(x+1)

p(x) = (x²-6) (x+1)

therefore x+1 is one of its factora

Answer:

remittance

Explanation:

Ang mga migranteng manggagawa, o sa ating bansa ay tinatawag na mga OFWs o overseas Filipino workers, ay mga mamamayan na nagibang bansa upang maghanapbuhay o magtrabaho.

Sila ay nagpapadala ng pera na kanilang kinita doon sa kanilang mga naiwan na pamilya dito sa bansa. Ang kanilang pinapadalang pera ay tinatawag na remittance.

Makukuha ito ng kanilang pamilya sa mga remittance centers. ilan sa mga tanyan na remittance centers sa bansa ay ang katulad ng Western Union, LBC, at iba pa.

Ang mga remittance centers na mga ito ay nagsisilbing paraan para mapadali ang pagpapadala ng pera kahit nasaang lupalop ka man sa mundo.
