(10.01 MC) Which of the following describes air temperature and air pressure at higher altitudes?
O Air temperature increase while air pressure decreases
O Air temperature and air pressure both decrease
Air temperature and air pressure both increase
O Air temperature decreases while air pressure increases

last one : air temperature decreases at high altitude and air pressure increases which makes us hard to breathe.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
