I believe the answer is A!
The doughnut because it contains carbohydrates
Solve the
potential energy at point B
PE = mgh
Where m is
the mass
G is the
acceleration due to gravity 9.8 m/s2
H is the height
PE = ( 1.5
kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Solve the
velocity using the
KE = 0.5mv^2
Where ke is
the kinetic energy
M is the
mass
V is the
velocity
Since all
energy is converted to KE
So KE = PE
7.35 = 0.53(1.5)
v^2
V = 3.13 m/s

The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
Answer:
The GIT mucus lining of the GIT serve as a physical barrier to the movement of digested food substances.
The mucus also help to prevent inflammation of the bowels; by reducing or suppressing immune response to inflammation.
In Cystic fibrosis, the blockage of the ducts by the mucus, prevents enzymes from reaching the digestive food substances,. The resulting undigested food substances leads to bloating, pain, cramps, gas, smelly belch, constipation, and smelly stools.
Explanation:
