Why can estrogen be delivered orally via a pill but testosterone cannot?

(I'm a transgender man, and it seems rather odd that trans women can just take a pill and I have to have a shot once a week.)

Is the strong force range a sharp cutoff or more of a gradient?

Posted: 20 Sep 2019 11:19 PM PDT

The range of the strong nuclear force is given as 1E-15 m, but at that limit does the force end suddenly or more gradually fade into nothing?

Why, chemically, does lobularia maritima have its honey like smell?

Posted: 21 Sep 2019 01:46 AM PDT

How is this chemical, or range of chemicals, synthesised? Where else do they/does it show up?

Ecologically, why does it have this smell in particular? More generally, why do different flowers have such a diverse array of smells? Also, why do these smells tend to be "sweet"?

Is there a difference in the speed of breakdown between amylose and amylopectin?

Posted: 21 Sep 2019 04:05 AM PDT

In my mind amylopectin should breakdown faster. Because of its branch points surely it could be acted upon by more enzymes and therefore broken down quicker. This was my belief up until recently where I performed an experiment involving light transmission to record the speed of starch breakdown. My results show the complete opposite. Maize starch which is a majority amylopectin breaks down significantly slower than potato starch which is a majority amylose.

If I were to throw a tennis ball in the air while I was standing still in a moving train, why doesn't the ball go flying back towards the back of the train and instead just goes up and down as it would if I were to throw it while on the ground?

Do quarks in an anti-proton/anti-neutron have anti-color charges?

Posted: 20 Sep 2019 06:38 PM PDT

If the quarks in a proton or neutron oscillate between color charges red/green/blue. do do they oscillate between anti-colors in anti-matter? I know they have opposite electric charge, but do they also have opposite color charge?
