For question 3, it would not leak through the whole sandwich because the cell membrane is thick
A. Vili in stomach. And this is because of gluten.
i think the answer is B, i may be wrong... because potential energy is stored energy and kinetic energy is energy due to motion so the less potential energy the more kinetic energy
and mechanical energy means the energy of motion, such as a moving vechile which is using kinetic energy.
As the gills does not develop into gills, they are likely to
contribute to the development of the lower jaw of the human embryo though after
the embryonic stage, the gill slits won’t be retained or won’t be a part of a
human as they only appear during embryonic stage for the development of the
lower jaw.
