Answer: The effect will be either an abnormal protein, a non functional protein or a protein with altered function or functions.
Explanation: Every protein performs at least one specific function. Example is the case of sickle cell disease where a protein called haemoglobin which is responsible for oxygen transport in the body is mutated. In the sickle haemoglobin, valine replaces glutamate at position six of the two beta chains. Haemoglobin is a protein with four subunits made up of two alpha chains and two beta chains. The substitution of glutamate residue withwresults valine results in the haemoglobin having low affinity for oxygen binding and consequently, inefficient supply of oxygen to the cells.
Oil, oil is made from things that has died thousands/millions of years ago.

Answer:
c) The presence of an ephiphyseal line
Explanation:
The options should be:
a) the presence of osteoblasts
b) the presence of osteons
c) The presence of an ephiphyseal line
d) the presence of hyaline cartilage on the ends of the bone
Explanation:
In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.
From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.
Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.
Speed = frequency x wavelength
100 x 0.2 = 20
