Which of these beakers contains an egg that would shrink?

Answers
Since water is more concentrated in the egg's interior of beaker 3 than the exterior, this egg will shrink. Water will move, by osmosis, from inside the egg to the exterior. The correct option is a) Beaker number 3.
In any of these situations, water will move through osmosis, if it moves.
What is osmosis?Osmosis is the water molecules transport by simple diffusion through the semipermeable membrane, following a concentration gradient.
Water molecules can freely move through momentary openings in the membrane that are formed as a result of lipids movements.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -for instance, the interior of the cell and another solution- are separated by a semipermeable membrane.
Since water moves according to its concentration gradient, we need to consider in which side of the membrane water is more concentrated.
The egg will shrink only if it loses water. And it will lose water if it is more concentrated in the interior of the egg than in the exterior.
Beaker Water concentration Water movement
inside the egg outside the egg
1 93% 93% No movement
2 80% 91% To the interior
3 99% 92% To the exterior
4 90% 95% To the interior
In beaker 3, water is more concentrated in the egg's interior than the exterior. This egg will shrink because water will move from inside the egg to the exterior.
The correct option is a) Beaker number 3.

The glucose and ethanol similar in structure and function as the ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.
What is the process obtaining ethanol?Ethanol has been obtained from three important steps and these are mentioned below:
Measure a quantity of a solution of sodium dichromate acidified in a dilute sulphuric acid and pour into a test tube.Add excess ethanol. This is because if we don't do so there will be plenty of oxidizing agent to carry out a second operation which changes the aldehyde to ethanoic acid. However, we need only the aldehydeWhen the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from orange to green, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.Therefore, the glucose and ethanol similar in structure and function as the ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

There will be an increase of aquatic plants and fish.
It could increase dissolved oxygen for fish.
Nitrogen levels could cause algae blooms.
There will be decreased nutrients in the water.
Answers
Global treaties are laws that are enacted by the government of a country to protect the marine environment from pollution.
The major hindrances that the government may encounter when enforcing these laws is that the funds that may be generated from agencies can be embezzled through corruption of individuals in charge.
After a heavy downpour (heavy rain), there is every tendency of water runoff from farms, suburban lawns, and wastewater treatment plants into local rivers, and eventually into a local bay.
This will lead to accumulation of excess nutrients and nitrogen in the water bodies leading to the formation of algae blooms.
Algae blooms occurs as a result of explosion of algae growth due to excess nitrogen and nutrients in the water bodies.
