Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.
Answer:
The foam will be formed only in glass B and D.
Explanation:
fermentation is a chemical reaction and procedure of breaking up a specific substance by microscopic organisms, or for this situation, yeast. The yeast in glass b was enacted by including warm water and sugar. The foaming outcomes from the yeast eating the sucrose.The sugar aging procedure emits heat as well as gas as a waste products. In this test glass b emitted carbon dioxide as its waste.
Yeast organisms respond distinctive in different situations. Had you attempted to blend yeast in with sugar and cold water, you would not have had similar outcomes. Nature matters, and if the water were excessively hot, it would kill the yeast microorganisms.
The yeast alone doesn't respond until sugar and warm water are added and blended to make the maturation procedure. To additionally research how carbon dioxide functions in this procedure, you can blend yeast, warm water and sugar in a container while connecting a baloon to the open mouth. The bloon will grow as the gas from the yeast aging ascents.
Answer: 25 %
Explanation: Adenine and Thymine are base pairs in DNA chain.
So their amounts are equal.
