A.
Nutrients from fertilizers on the farm wash off into the lake and cause the green slimy algal bloom
Explanation:
This question describes a team of marine biologists, who observe an inland sea covered up with a green slime. Firstly, this green slime is the the visible form of the proliferated growth of algae, hence, causing what is referred to as ALGAL BLOOM.
Algal bloom is caused by EUTROPHICATION, which is the pollution of water bodies with nutrients from fertilizers e.g phosphate, nitrate etc which causes a rapid algae growth. The excessive nutrients causing this algal bloom appearing like a green slime comes from the fertilizers used by farmers practising large scale farming within that area.
When this fertilizer is applied on plants, it gets washed into the water body and its constituents e.g phosphorus, nitrogen etc. serves as source of nutrient for the growth of marine organisms (algae). Hence, they grow excessively and form a bloom that appears like a green slime on the lake.
Hence, the farming activities is releasing pollutants in form of chemical substances which serve as nutrients for the proliferated growth of algae.
The A1C is a test, which is used to measure the blood glucose level by assessing the amount of the glycated haemoglobin. It is also known as the haemoglobin A1C or HbA1C test.
The normal level of the A1c is below 5.7%, an HbA1C level between 5.7 and 6.4 shows the signals of prediabetic condition, if the A1C test shows sugar eve more than 6.5, the person is affected with diabetes.
Hence, Sarah should tell her that this test is done test, if you are diabetic or not. And, in case, you are not, you are prone to diabetes in near future or not.
Answer:
In 1884, Hans Christian Gram described a method of staining bacterial cells while not staining surrounding animal tissues. However, he thought that the staining method he developed was faulty because not all bacteria stained. ... Not all bacteria stained because some have walls that prevents the staining.
