For many of their illnesses scientist and doctors haven't treated them before so they don't know how to treat them or exactly if the animal can handle the treatment
Answer:
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing.
Simple, both guinea pigs have the dominant B traits in them, and the DNA code combines to make the dominant trait the one most present in the offspring.
Copper bracelets and magnetic wristbands are used relieve pain in people with arthritis. Studies conducted on these devices show that they have no efficacy on pain or on stiffness, two of the most characteristic symptoms of arthritis. Although there is no medical data to support the efficacy of the copper bracelet, the patient is not harmed or endangered by wearing it. Therefore, the nurse should respect the fact that the patient is feeling better, but he/she should urge the patient to continue with its prescribed medication.
CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix 
into organic acids during the night.
The correct option is a.
As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.
During the day, the malate is transferred to chloroplasts where it is transformed back to 
, which is then utilised during photosynthesis. At night, the is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected , which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.
