I got you :)

The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.

Refer to the erg to find the potential hazards to health for un1825

Nat2105 [25]

UN1825 refers to Sodium monoxide.It is a white granular material. It reacts with water to give sodium hydroxide with the evolution of heat. It is corrosive to metals and tissue. The oxides of sodium and potassium react with water vigorously and with enough evolution of heat to cause boiling and spattering of hot caustic solution.Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

each of the following molecules is processed by glycolysis to pyruvate. how much net atp is generated starting with each molecul

ki77a [65]

From glucose $2$ ATPs are produced.

ATP:

One glucose molecule is divided into two pyruvate molecules during glycolysis, requiring two ATP molecules while generating four ATP molecules and two NADH molecules.
For the cell to utilize as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules.
Glucose breaks down into pyruvate and energy during glycoses
From glucose 6- phosphate to lactate 3 ATPs are produced.
$4$ ATPs are generated from which one is utilized when fructose $6$ phosphate is converted to fructose $1, 6-$ bisphosphate. So the net yield is $3$ ATP.

From dihydroxyacetone phosphate 2 ATPs are produced.

As the cycle occurs only once either from DHAP or PGAL (glyceraldehyde $3-$ phosphate)

Three irreversible reactions of glycolysis:

Hexokinase

Glucose + ATP $\rightarrow$ Glucose $-6-$ phosphate + ADP

Phosphofructokinase-I

Fructose $-6-$ phosphate + ATP $\rightarrow$ Fructose $-1, 6-$ bisphosphate $+$ ADP

Pyruvate kinase

$\mathrm{PEP}+\mathrm{ADP} \rightarrow$ Pyruvate $+$ ATP
