Hello, this seems like a multiple choice question without the given choices. However, I can still help you and give you an idea that can potentially help you choose the choice.
Fats can contribute to issues regarding digestion and respiration when consumed too much since it clogs up your arteries. If large amounts of fat is continuously consumed for a lengthy period, then obesity and fatal chronic diseases can be a result. For your question, choose the option with the food that has the fattiest content.
I hope I was able to help you with your question! :)

D. Loss of the upward force opposing gravity
Explanation:
A hanging apple from a tree branch will fall when it loses the upward force opposing gravity. The force of gravity is directed towards the center of the earth and it pushes all bodies downward.
On the apple, the forces acting on it are:
- downward force of gravity
- Upward force holding it by the fruit stalk.
According to Newton's first law "a body will remain in it's state of rest or uniform motion unless an external force acts on it "
The apple is initially at rest when the force of gravity equals the upward force :
Force of gravity = Upward force
The two forces acts in opposite direction and cancel out.
When the downward force is lost by stalk holding the fruit, gravity wins and the fruit falls;
Force of gravity - Upward force = Net force = falling of the fruit
In case we push up the fruit, the upward force overcomes and it moves upward:

Answer:
A)
Concentration of hemoglobin = weight of the hemoglobin / total volume of RBCs
Therefore,
weight of the hemoglobin = concentration of the hemoglobin x Total volume of RBCs
weight of hemoglobin = (8.7x 10⁻¹¹ x 0.34) g
= 2.96 x 10⁻¹¹ g
B)
molar mass of hemoglobin is 64500g/mol.
molar mass (m) = number of moles (n) x M,
∴ n = m/M
so number of moles in 2.96 x 10⁻¹¹ g of hemoglobin with molar mass 64500g/mole
= 2.96 x 10⁻¹¹ / 64500
= 4.5 x 10⁻¹⁶ moles
using Avogadro’s number to calculate the number of molecules from moles.
1 mole = 6.022 x 10²³ molecules
so, 4.5 x 10⁻¹⁶ moles
= 4.5 x 10⁻¹⁶ x 6.022 x 10²³
= 2.71 x 10⁸ molecules
Explanation:
Note: Average volume of a red blood cell = 87 μm³ = 8.7 x 10⁻¹¹ ml
The mean concentration of hemoglobin in red cells = 0.34g/ml.
