Answer:
kL, dL, mL, pL
Explanation:
pL stands for picoliters. This is equal to 1 × 10⁻¹² (0.000000000001) liters.
mL stands for milliliters. This is equal to 1 × 10⁻³ (0.001) liters.
dL stands for deciliters. This is equal to 1 × 10⁻¹ (0.1) liters.
kL stands for kiloliters. This is equal to 1 × 10³ (1000) liters.
I got this idk if it's correct: For measuring large distances, the kilometer (103 or 1000 meters) is often used. The basic unit of volume in the metric system is the liter (l). The most common derived unit is the milliliter (ml) (10-3 or 1/1000 of a liter). The volume of a milliliter is equal to the volume of a cube 1 centimeter per side.
Evolution can not be tested by experiment given that it depends largely on observations that fit into a wider scope and point to a common conclusion.
<h3>Can evolution be proven empirically?</h3>
Science is know to be empirical, In science, the evidence that backs up a claim is what establishes it as true or false. Thus all theories must be tested by experiment.
However, the theory of evolution can not be tested by experiment given that it depends largely on observations that fit into a wider scope and point to a common conclusion. In other words, evolution lies “outside of empirical science”.
The fact that it can not be directly proven empirically does not necessarily make it out to be false. That was the conclusion of Paul Ehrlich in his 1967 article.

Answer:
b) [bicarbonate]/[carbonic acid] = 9.4
Explanation:
The pH of a buffer system is given by the Henderson-Hasselbach equation:
- pH = pKa + log ([bicarbonate] / [carbonic acid])
Where pka = -log (Ka) = -log(4.2x10⁻⁷) = 6.38
Now we <u>solve for [bicarbonate] / [carbonic acid]</u>:
- 7.35 = 6.38 + log ([bicarbonate] / [carbonic acid])
- 0.97 = log ([bicarbonate] / [carbonic acid])
= [bicarbonate] / [carbonic acid]
- [bicarbonate] / [carbonic acid] = 9.33 ≈ 9.4
So the answer is b).
