what is meant by the terms resolve in gel electrophoresis?
Gel resolution in gel electrophoresis simply means the degree of separation between the proteins and DNA of different molecular weights.
Gel electrophoresis simply means a laboratory method that is vital for the separation of mixtures of RNA, DNA, or proteins based on their molecular size.
It should be noted that in gel electrophoresis, the molecules that are to be separated are pushed with the aid of an electrical field through a gel that has small pores.
Gel resolution in gel electrophoresis depends on the cross-linking polymer which was used in making the gel and the other materials that provide the gel with the specific desired properties.

Answer to the following questions in complete sentences.
What is seen when phenolphthalein is added to distilled water?
Why do you think you had to use distilled water, which is pure water, rather than tap water?
What is seen when phenolphthalein is added to the filtered water with chalk? with calcium hydroxide?
What does it mean that the filtered water samples reacted with phenolphthalein?
When phenolphthalein is added to distilled water, no changes will be observed in the reaction.
What do you mean by Phenolphthalein?Phenolphthalein may be defined as an organic compound of the phthalein family that is widely employed as an acid-base indicator.
The distilled water is free from any impurities because it is sterilized before use. The pH of distilled water is neutral, while the pH of tap water ranges from 6.5 to 8.3, which affects the products of the given reactions.When phenolphthalein is added to the filtered water with chalk or calcium hydroxide, it gives a pink color. Filtered water samples mean those water samples which are filtered and the impurities are removed by physical appearance only. It overall does not change the properties of the water sample.Therefore, all the questions are described above one by one.

1. Colorless solution.
2. To avoid interference from impurities in tap water.
3. Pink color (chalk), no reaction (calcium hydroxide).
4. Presence of alkalinity in chalk-filtered water.
1. Phenolphthalein in distilled water is colourless. Pure distilled water does not contain contaminants that might react with phenolphthalein to change colour.
2. Phenolphthalein readings are accurate with distilled water. Tap water may include minerals, salts, and contaminants that react with the indicator and cause a misleading or confusing colour shift. Distilled water eliminates these interferences, revealing the indicator's behaviour.
3. Phenolphthalein turns chalk-filtered water pink. Calcium carbonate in chalk forms calcium hydroxide with water. This reaction raises water alkalinity, turning phenolphthalein pink.
4. The pink colour of chalk-filtered water samples suggests alkalinity, but calcium hydroxide does not modify the colour and phenolphthalein does not react. This phenolphthalein indicator detects alkaline characteristics in water samples.

What is the voltage of a galvanic cell made with magnesium (Mg) and gold
(Au)?
O A. 4.2 V
OB. 0.54 V
O C. -0.54 V
O D.-4.2 V
A. 4.2 V is the voltage of a galvanic cell made with magnesium (Mg) and gold(Au).
What is the voltage of a galvanic cell made with magnesium?The bigger the reduction ability, the more likely the steel is to be reduced and act as the oxidizing agent. Returning to the copper-magnesium galvanic cellular, the same old electrode potential of copper is 0.337 volts, whilst the standard electrode capability of magnesium is -2.370 volts.
Cell voltage is also known as cell ability (E) and electromotive force (emf). the electrical voltage or ability is measured in volts (V). The volt is related to strong values, joules (J), and electric powered fee, coulomb (C). The connection between these is defined with the equation: 1J=1C×1V.

which of the four muscular chambers of the human heart directly propels blood into the pulmonary circulation?
Answer:
the right ventricle
Explanation:
right side pumps deoxygenated blood into the pulmonary circulation
The right ventricle is the muscular chamber of the human heart that directly propels blood into the pulmonary circulation.
What is circulation?The movement of blood through the body's vessels which is basically is brought about by the heart's pumping motion serves to transport nutrients and oxygen.
It occurs to all regions of the body and eliminate waste products from them.
Deoxygenated blood from the right atrium is used up by the right ventricle and pumped into the pulmonary artery, which then transports the blood to the lungs for oxygenation.
After being given oxygen, the blood travels back to the heart through the pulmonary veins, where it enters the left atrium before being pumped into the left ventricle for systemic circulation throughout the body.
Thus, the answer is right ventricle.

Explain why when you look at a leaf it appears to be green?
The leaf appears to be green because the plant leaf absorbs all the light rays of the sun except the green, and as the green is reflected back to the atmosphere, the plant leaf appears to be green.
What is the reason behind seeing different colors?Different colors are produced from the sun's light, so when the light is passed through the prism or through the water droplets, due to the scattering of lights, the colors are produced. As the plants' leaves have differing colors such as green, orange, little brown, etc., this is the result of the different photosynthetic pigments such as chlorophyll, xanthophyll, etc . The colors that are absorbed by these are not visible to the eyes, but those that are reflected back are seen.
Hence, the leaf appears to be green because the plant leaf absorbs all the light rays of the sun except the green, which is reflected back and is visible to the eye.
