Which question is testable?

Nuetrik [128]

The correct answer is: A. How does changing the amount of water affect the growth of corn?

While options B, C & D are not impossible to test, option A is the only question that can be tested using quantitative methods, such as statistical analysis. The question in option A states: "How does changing the amount of water affect the growth of corn?". This question is easily testable using scientific investigation, because controlled or measured amounts of water can be added to corn, and the consequent growth rate of corn can be easily measured and recorded. However, the questions in options B, C & D cannot be precisely measured using quantitative tools, since they aim to measure qualitative (subjective) factors, such as: ethics, happiness and disappointment.

Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates

mestny [16]

Answer and Explanation:

Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.

It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.

Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.

In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.
