People with hemophilia need to have clotting factor proteins injected into their cells throughout their lifetime. Based on what you observed when you added proteins to change Greg’s stripe color, why do you think people with hemophilia constantly need to receive injections of the protein? *

people with hemophilia constantly need to receive injections of the protein because, hemophilia can causes internal bleeding in severe cases, which can result in the damage of organs and joint. This is because people who have hemophilia lack a specific protein (which is called a clotting factor) that enables blood to clot.

Explanation:

Hemophilia is a hereditary bleeding disorder which is characterized by either decreased, defective or absent production of blood clotting proteins.

The treatments needed will depend on the type of hemophilia and the severity of hemophilia. For example, if you have mild hemophilia (that is relevant clotting factor activity is greater than 5%, but less than normal), you may need treatment only when you are in preparation for a surgery or when you have an injury. However, if you have severe hemophilia that bleed frequently, you may need regular (several times in a month) to help prevent bleeding and help protect your joints from deformity and disability.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
