Answer: Option C.

Inefficient oxygen transportation.

Explanation:

Sickle cell anaemia is an inheritable condition in which the red blood cells cannot carry oxygen to the organs or whole body because the red blood cells shape has been distorted and is sickle in shape. In this condition there is not enough red blood cells to carry oxygen in the blood.

Red blood cells function to transport oxygen in the blood because of the haemoglobin molecule present in them.

This can damage the organs nerves,lungs, livers spleen e.t.c

If a bowler rolls a bowling ball at a constant speed, would the force increase if he or she changes the weight of the ball? Expl
CaHeK987 [17]

Answer:

This is what we call Potential Energy and Kinetic Energy

Explanation:

If the bowler is rolling a ball, let's say 5 LBS, It should travel at normal speed.

The speed is also dependent on how the bowler throws the ball.

If they were to change the weight of the ball. It would most likely slow the ball down more, as it would be too heavy to go as fast if it was a lightweight ball.

It's like a person. The bigger and heavier they are, the slower they will move with their own consecutive speed. If they are lighter, they'll most likely go faster
