comment What part of the cactus photosynthesizes?
Since photosynthesis is correlated with chlorophyll, I'm guessing the green part.

comment Exercise causes number of cell divisions to approach Hayflick limit faster? And hence shorten life expectancy?
I don't know about the Hayflick limit in humans, but Olympic-class athletes tend to live longer than average, as long as it wasn't a contact sport: well.blogs.nytimes.com/2012/12/19/live-as-long-as-an-olympian

comment Can this theory on the evolution of human appearance be flawed?
What he's getting at is called homogeneity, for future reference. At least, I think so. 'Completely average looks' means very little in a biological context since evolution works on a genetic scale.

comment Difference between “transcriptional activity” and “RNA expression”
I'm not familiar with what you're doing, but off the top of my head I'd say that the RNA Expression might be referring to everything post-nucleus in that the Introns are missing. The Transcriptase would show more activity because it would still Transcribe both Introns and Exons.

comment Are there examples of encryption in nature?
You may want to define what you're looking for a bit better. Isn't something that appears random, but is actually a complex formation practically the same as encryption? I don't see the difference between your first and second sentences in your second paragraph.

comment Melting point of a fatty acid?
You'll want to wait for a full answer. All of the answers will affect the melting point to some degree, but whether it's a significant amount is another thing.

comment How can the child and the mother have different blood types?
The fetus makes its own erythrocytes from a combination of the father's and mother's genome. If the mother is B and the father is A, the child will be AB as they are co-dominant. Only 'O' is recessive. This may be a too-basic question for this site...

comment Melting point of a fatty acid?
Are you looking for one answer of the 5, or are multiple answers possible? If it's the latter, then it's 1, 4, 5 from a quick recollection.

comment I'm 20. Can I still grow taller?
@rg255 - Sure, there's going to be variance in everything. However, I don't want to mislead, so I use the averages. Answering 'Yes' when you're talking about 10% of the population is misleading to me.
