Answer:

Glucose - from the food we eat, then the food is broken down into another type of sugar called glucose.

Amino Acid - animal proteins such as meat, eggs and poultry. When you eat protein, it is broken down into amino acids.

Oxygen - we get oxygen by breathing in fresh air.

During the developing of a TLC plate, it is common to place a cover on the chromatography chamber and have a piece of moist filt

Artyom0805 [142]

Answer:

The moist filter paper is in charge of preventing evaporation and ensuring the proper saturation of the air of the chromatography chamber.

Explanation:

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures.

A strip of moist filter paper is put into the chromatography chamber so that its bottom touches the solvent and the paper lies on the chamber wall and reaches almost to the top of the container.

The container is closed and left for a few minutes to let the solvent vapors ascend the moist filter paper and saturate the air in the chamber.

The moist filter paper is in charge of preventing evaporation and ensuring the proper saturation of the air of the chamber.

At room temperature, good conductors of heat usually feel cool to the touch. This is because they conduct heat so quickly that w

sp2606 [1]

C. copper

Explanation:

Copper is the best conductor of heat from the given options. Plastic, wood and cotton are all poor conductors other wise known as insulators.

Metals are typically good conductors of heat.

they generally do not have a high specific heat capacity which implies that they get heated easily.
a good conductor allows heat to flow fast and it simultaneously loses heat readily too.
copper is a good conductor, when heat its perfectly allows heat to pass through
when heat is removed, it loses it very fast.

You are given three pieces of wire that have different shapes (dimensions). You connect each piece of wire separately to a batte

VikaD [51]

Answer:

$R_3 < R_1 < R_2$

Explanation:

The resistance of a wire is given by:

$R=\frac{\rho L}{A}$

where

$\rho$ is the resistivity of the material

L is the length of the wire

A is the cross-sectional area of the wire

1) The first wire has length L and cross-sectional area A. So, its resistance is:

$R_1=\frac{\rho L}{A}$

2) The second wire has length twice the first one: 2L, and same thickness, A. So its resistance is

$R_2=\frac{2\rho L}{A}$

3) The third wire has length L (as the first one), but twice cross sectional area, 2A. So, its resistance is

$R_3=\frac{\rho L}{2A}$

By comparing the three expressions, we find

$R_3 < R_1 < R_2$

So, this is the ranking of the wire from most current (least resistance) to least current (most resistance).

Write a speech about bringing back fidget toys because they're banned in school

12345 [234]

I believe that fidget toys should not be brought back in school, reason being is because fidget spinners were originally made for students with example: Autism . Who actually needed them. Now that people who don't need them are buying them and playing with them in the classroom, it causes a complete distraction and is not being used for its original purpose whatsoever .

Thomas needs to move an 80 kg rock, but cannot lift it. He decides to use a

ArbitrLikvidat [17]

Answer:

Explanation:

The weight of the rock is W = mg = (80 kg) (10 m/s²) = 800 N.

The mechanical advantage is therefore 800 N / 200 N = 4.
