Well, I'm sure you know that you need to draw out the triangle and the altitudes of the triangle.    The orthocenter is where the lines of altitude intersect. If they don't intersect inside the triangle, you need to extend the lines with a ruler or straightedge, until they do.    Even...

Hi, Sheyanne!   The operator is the portion of DNA, at the beginning of a gene, where a transcription factor or repressor binds. If the transcription factor cannot bind, the RNA Pol cannot attach to begin transcription.   I hope this helps!   Regina G.

Are you doing IR spect?    In spect, you need to check the absorption charts and look to see if there are absorptions in the fingerprint region.

If your question is using an mRNA transcript as a template for protein synthesis, well, you would need ribosomes, the transcript, tRNA and the amino acids to be added.   If you mean putting amino acids in a tube with the right solution to allow the dehydration reaction to add an amino...

Sorry this is late in coming, Nadeshiko. When is oxygen the terminal electron acceptor? At the end of the ETC, which occurs after what cycle?   Whether they use H2 or H2SO3 to get everything started doesn't matter What matters is which method the bacterium uses to extract energy...

For the square roots, the radicand cannot be negative, or you'll end up with an imaginary number.    So, set the radicand ≥ 0 and solve for the value of the variable, observing all the rules of inequalities.   For part b, as an example, you have the sqrt(5-x)...

I answered on the other question you asked. Double-check the formula you put here, as I think it needs a plus sign, in the parentheses.    Also, use the other problem to guide you through this one. I hope you'll share your work, so we can help you through this one if you get stuck...

As it is written, this is simplified. You cannot combine any of these terms, unless you're given values for the variables.

You need to rearrange to isolate the variable t.   Starting with the formula A = P (1+r/n)nt   Isolate term with unknown exponent A/P = (1+r/n)nt   It might be useful to plug the values in, at this step, to simplify the work.   (1700+500)/1700...

Hi, Irysha,   I think you have been given a thorough explanation of differentiation, but if you need a one-liner, try thinking on this: Differential gene expression leads to differences in structure and function of cells, which can form tissues and organs. Edit: I...
