4 0

Answer:

The addition of sugar and salt to the food material result in the increase in the osmotic pressure, which help to destroy the bacteria and help in the preservation of food.

Explanation:

addition of salt or sugar help to preserve food because

  • by adding salt to the food material it absorbs the water and high concentration of salt inhibit the growth of microbe and if the water is not present in food bacteria will not able to reproduce by this way addition of salt help in the preservation of food.
  • by adding sugar to the food material it reduces the water content which prevent the food from microbial spoilage.if the sugar concentration is high ,the bacteria to lose water and if enough water is not present bacteria will not able to grow

thus by this way addition of salt or sugar help preserve food.

What are the sequence of steps that includes the image on the retina
jonny [76]

Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.

Explanation:

Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.

From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.

From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.

Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.

Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.

The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.

Generally speaking, what effect does temperature have on the solubility of gases in liquids?
MrRa [10]

With the increase in temperature, solubility of gases in liquid decrease.

Option A

<h3><u>Explanation:</u></h3>

Gases are soluble in liquid but it's solubility depends on temperature and pressure. As the temperature increases, the solubility of gases decrease. It is because with the increase in temperature, the kinetic energy of both the molecules of gas and the solvent increase. This leads to increase in molecular vibration and this makes the gas molecules escape the solution.

This makes the gas solubility vs temperature graph have a hyperbolic curve. As the temperature increases the solubility decrease and vice versa.
