I'm not exactly sure what the answer is but if one of the options are ..90% I would go with that one
Sorry if this didn't help..
Answer:
An average woman needs to eat about 2000 calories per day to maintain, and 1500 calories to lose one pound of weight per week. An average man needs 2500 calories to maintain, and 2000 to lose one pound of weight per week. However, this depends on numerous factors.
Explanation:
Answer:
The answer is B, I believe, because it states here that, "Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. ... The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction."
The genetic code is carried by the DNA molecule in most organisms. DNA is the store for hereditary information.
In eukaryotic cells, DNA is found in the cell nucleus, while in prokaryotes it is found in the nucleosome.
The genetic code is the triplets of nucleotides in DNA and RNA that define and direct which amino acid is used in protein synthesis.
The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Three of these triplets are called non sense triplets or codons because they do not code for any amino acid. The rest are sense codons.
B)<span>When you listen to the heart sounds, you are hearing the flow of blood which stops abruptly when a heart valve closes. This produces the "lub-dub" sounds. 1st heart sound (when the Mitral Valve closes) as the ventricle contracts (systole) and then 2nd heart sound (when the Aortic Valve closes) and the ventricle starts to fill again (diastole)
</span><span>The pulse is the wave of pressure you can feel through the artery walls. This denotes systole.
</span><span>The ECG's QRS complex is the electrical signal that tells the Ventricles to contract. You can see that the QRS occurs right at the beginning of systole and triggers Isovolumetric contraction.
</span><span>So the QRS on the ECG, the pulse wave you can feel (ie. the rise in aortic pressure) and the 1st heart sound all signify SYSTOLE.
</span><span>there a delay between systole of the ECG and the resulting pulse felt in the finger (R-Pulse) </span>because it takes a little bit of time for the pressure to transmit through the body, as the finger is not on the heart (if it was there would be no delay)
