Experiments cannot validate hypotheses, only falsify them

The statement above can be restated in which of the following ways?

A spectrophotometer is an instrument that measures the intensity of light absorbed after it passes through a sample solution. With the spectrophotometer, the concentration of a chemical substance can be determined by measuring the intensity of light detected.

Uracil is the nucleotide that is only found in RNA. The other nucleotides are found in both DNA and RNA

The renal vein drains deoxygenated blood from the kidneys to the inferior vena cava.

From the heart, blood flows through major arteries, which then branch to give rise to arterioles, which then divide into capillaries that deliver blood to the target organ.

Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane is a barrier that surrounds the cell and separates its internal environment from the external environment.

Cardiac muscles have intercalated discs that enable them to contract in a coordinated manner. Skeletal muscles do not have intercalated discs, as their contraction is under voluntary control and does not require the same level of synchronization seen in the involuntary contraction of cardiac muscle.

This is the plate with the most growth despite the presence of antibiotic cover.

The kidneys are the primary organs involved in the excretion of nitrogenous wastes. Nitrogenous wastes are mostly products of protein metabolism in the liver. One of the common nitrogenous waste products is urea, which is excreted through the kidneys.

The pH scale is logarithmic, indicating that each whole number change on the pH scale represents a tenfold change in acidity or alkalinity. Therefore, a substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4.

This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.
