1.) the metric system is universal
2.) this system of measurement makes it possible for scientists from all parts of the world to understand and agree upon the measurements taken within an experiment.

The metric system is used because it is based on the number 10. Ten is easy to use for mathematical operations and conversions.

It is also easy to use for scientific notation when you are referring to powers of ten. There are extremely large and extremely small numbers in science. Thus, scientific notation allows for accurate abbreviated ways to symbolize these numbers. For instance, if I were to say 1,000, in scientific notation it would be 1 x 10 ^3. If I was to say 1,000,000, I would scientifically write 1 x 10 ^6.

Which statement about uncouplers is NOT true? A. They allow ATP synthesis with no electron transport. B. They allow electron tra
Arturiano [62]

Answer: the statement that is wrong about uncouplers is option A ( they allow ATP synthesis with no electron transport).

Explanation:

An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.

2,4-DNP is an example of an uncoupler.

1. In apothecaries' measures: 1 scruple = 20 grains, 1 ounce = 480 grains, 1 oz = 28.34 g
laila [671]

Answer:

5.89 g × 10⁶ μg

Explanation:

Step 1: Convert 5.00 scruples to grains

We will use the conversion factor 1 scruple = 20 grains.

5.00 scruple × 20 grain/1 scruple = 100 grain

Step 2: Convert 100 grains to ounces

We will use the conversion factor 1 oz = 480 grains.

100 grain × 1 oz/480 grain = 0.208 oz

Step 3: Convert 0.208 oz to grams

We will use the conversion factor 1 oz = 28.34 g.

0.208 oz × 28.34 g/1 oz = 5.89 g

Step 4: Convert 5.89 g to micrograms

We will use the conversion factor 1 g = 10⁶ μg.

5.89 g × 10⁶ μg/1 g = 5.89 g × 10⁶ μg
