The correct answer is C) the fluorescent cells can help track the movement of cells.
Explanation:
In the last years, geneticists and scientists created animals that glow in the dark by inserting a Green Fluorescent Protein or GFP gene found in some species of jellyfish. This protein was used in animals such as rabbits, rats, and even chickens. One of the key reasons for this is that by inserting fluorescence scientists can better observe the development and movement of cells. This includes analyzing cells reproduction and growing in embryos of "glowing" animals or inserting the protein in specific cells or organs in an organism to observe how these change or move. Thus, the purpose of studying fluorescent rabbits is that "the fluorescent cells can help track the movement of cells".

Answer:
Letter C
Explanation:
Salmon have a physiological adaptation that allows osmoregulation to occur in two different environments (seawater and freshwater). There are specific molecules in the salmon gills that "pump" and "remove" Na and Cl ions. When at sea these molecules pump the ions out of the salmon's body and into freshwater, the same molecules remove Na and Cl from the water bringing it into the animal's blood.
I believe that in developed nations, the nutrients that are most lacking in a child's diet are the; calcium, iron and zinc. Zinc is needed for the activity of more than 100 different enzymes in the body and plays a role in the immune function. It aids in the maintenance of healthy immune function in kids and may reduce the frequency of mild upper respiratory tract infections. Calcium keeps the bones healthy and teeth thus supporting the skeletal structure and function. Iron is an important component of hemoglobin.
