Answer:
The correct option is D
Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, <u>it is </u><u>not true</u><u> that it involves just the x allele and thus affects males more often than females</u>.

People use plants as fuel for transportation and heat. ... Fossil fuels store carbon, just as living trees and plants do. When burned, they release carbon dioxide into the air. The large and growing amounts of carbon dioxide in our atmosphere cause Earth's climate to warm.
The compatibility of a person’s temperament with his surrounding environment is referred to as “goodness of fit.”Some temperaments and environments seem to naturally fit together, while others do not.There are two types of “Goodness of Fit:”how that trait interacts with the environment how it interacts with the people in that environment.Any trait in and of itself is not a problem; rather, it is the interaction that determines the “acceptability” of that trait.
Answer:1. Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel, a scientist and Augustinian friar working in the 19th century, was the first to study genetics scientifically.
2. Over our lifetime, our DNA can undergo changes or mutations that result in differences in the DNA sequence and may affect the proteins that are made. Mutations can occur as a natural consequence of errors in DNA replication or as a result of exposure to environmental factors such as smoking, sunlight or radiation.
