Jams, jellies, preserves, honey, and other foods with high sugar content hardly ever become contaminated by bacteria, even when

the food containers are left open at room temperature. This is because bacteria that encounter such an environment:_______. A) are unable to swim through these thick and viscous materials B) are unable to metabolise the glucose or fructose, and thus starve to death C) undergo death as a result of water loss from the cell D) are obligate anaerobes

Answer:

C) undergo death as a result of water loss from the cell

Explanation:

In high sugar concentrations bacteria undergo death by a process called plasmolysis. Plasmolysis is a process by which bacteria lose water as a result of osmosis. The shrinkage of the protoplasm away from a plant cell wall due to water loss caused by osmosis is also plasmolysis

In other for the environment to maintain equilibrium, water moves from the bacteria (hypotonic) to the sugar solution (hypertonic) by osmosis i.e the movement of particles from a region of lower concentration to a region of higher concentration. It is this water loss that leads to the shrinking of the bacteria cell. The loss of water further hinders natural metabolism, and hence cell death.

Answer: this is because bacteria that encounter such an environment UNDERGO DEATH AS A RESULT OF WATER LOSS FROM THE CELL.

Option C.

Explanation: Water is a great medium of growth for bacteria. Several experiments have been carried out to support this statement. Also, it is a means by which the bacterium is transmitted from "a site" to another.

Why did Bill Nye pressurize the giant "cloud bottle"? What purpose did this serve?
zubka84 [21]

Answer:

Water molecule is present in air these airborne water molecule are called water vapor, when the molecules are present in air they don't normally stick together as the space is too much.

Bill Nye took a giant bottle and covered it with a stopper and started pressurizing it with a pump to make the molecules come closer and become compressed also it increase the temperature even slightly and that warmth will cause the liquid stick with the smoke particles to go back to forming as vapor.

After that he removed the lid then the air inside the bottle is spread out and it will eventually cool also the kinetically energy is also reduced and that cooled air sticks with dust particle which now forms cloud.

This experiment shows how the clouds are formed and the science associated with it.

Please I need help immediately, describe an experiment to verify the living organisms in the soil.​
Alborosie

Answer:

Soil living organisms compromise from mammals (such as rats) to micro organisms (such as nematodes and protozoa). Soil organisms help in the modification of soil, and also in the decomposition of organic matter. However they can also pose as a treat to to some crops, as they are responsible for some plant diseases.

Explanation:

When living organisms breathe they give out carbon dioxide gas as a waste product. Carbon dioxide gas can be detected (identified) using a carbon dioxide indicator solution called bromothymol blue. To find out if there are living organisms present in the four different levels of soil takenfrom the deciduous forest.

An essay about clubfoot
gizmo_the_mogwai [7]

Answer:

use this- Clubfoot is a deformity in which an infant's foot is turned inward, often so severely that the bottom of the foot faces sideways or even upward. Approximately one infant in every 1,000 live births will have clubfoot, making it one of the more common congenital (present at birth) foot deformities.

Bacteria can make their own folic acid, which is required for nucleic acid synthesis, but humans cannot and instead have to inge
lidiya [134]

This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
