*Sickle cell disease is a constitutional corpuscular hemolytic anemia related to an abnormal structure of the globin chain. It is an autosomal recessive disease, which means homozygosity is necessary to fully express the illness.
*It corresponds to the synthesis of an abnormal hemoglobin, HbS, which is different from normal Hb (HbA).
*The S allele (located in the chromosome 11), responsible for the anomaly, is especially widespread in the African continent, it is also found in other regions of the Mediterranean.

*Mutation GAG to GTG leading to the substitution Glutamine by a valine in position 6 of the chain of the globine.</span>
A statement that carbon is matter and cannot be created or destroyed is an example of part of a scientific theory and is denoted as option A.
<h3>What is a Theory?</h3>
This term refers to series of principles which helps to explain a particular phenomenon.
The most suitable choice will therefore be option A as it helps to explain why carbon can't be created or destroyed due to it being a matter and is the correct choice.

Answer:
Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.
<em>Note: The question does not specify any two elements.</em>
Explanation:
The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.
