If an abnormal rearrangement or alignment of the bones results from a fracture, it is called a fracture.

The displaced fracture is caused when the bone breaks into two or more parts and the bones are no longer in alignment with each other. These broken bones becomes abnormally arranged. Normally, these fractures are caused due to trauma. The bone breaks or cracks, and gets displaced from its original position, and then it gets arranged in the abnormal position.

Hence, the blank can be filled with 'displaced'.

Answer;

-Displaced fracture

Explanation;

-A fracture is the medical term for a broken bone. Fractures are common; the average person has two during a lifetime. They occur when the physical force exerted on the bone is stronger than the bone itself.

-In a displaced fracture, the bone snaps into two or more parts and moves so that the two ends are not lined up straight. If the bone is in many pieces, it is called a comminuted fracture.

-On the other hand, in a non-displaced fracture, the bone cracks either part or all of the way through, but does move and maintains its proper alignment.

the correct answer is anaphylaxis.

anaphylaxis is a condition caused by insect bites, foods, medications, manifested by tongue swelling, shortness of breath, vomiting, low blood pressure. it sometimes may occur without an obvious reason. it is treated with epinephrine injection.other tretments include antihistamines and steroids,

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
