Answer:
A. are caused by genes for defective proteins
Explanation:
Sickle cell anemia occurs when the gene coding for the beta chain of the hemoglobin has a substitution mutation. The mutant gene code for a faulty protein. The mutated hemoglobin forms aggregates and imparts sickle shape to the red blood cells carrying them. Similarly, hemophilia is caused due to mutation in the gene coding for Factor VIII.

H2O (water) CO2 (carbon dioxide) and the sun (light)
Answer:
4. It is not a mineral because it has a definite composition
Polar PERIPHERAL MEMBRANE PROTEINS are typically found attached to the outside of a membrane.
The membrane is majorly made up of phospholipids, which are bilayer in nature, having a polar head and a non polar tail. There are two types of membrane proteins; the integral and the peripheral protein. The peripheral protein is usually found on the outside of the membrane, attached to the polar head of the phospholipid bilayer.
