Answer:
<em>The correct option is A) cadmium dosage</em>
Explanation:
In an experiment, an independent variable can be described as a factor which is changed naturally or by us to see its effect on the dependent variable. The dependent variable is the variable which is under study and depends on the independent variable.
In the following experiment, we are checking the effect of different dosages of cadmium on the surviving ability of tadpoles. Hence, cadmium dosage is the independent variable. Tadpole population is the dependent variable.
Answer:
Fibrinogen
Explanation:
Fibrinogen is one of the proteins present in the blood plasma. It makes 7% of the plasma proteins. During the process of blood clotting, the active thrombin enzyme serves to convert soluble fibrinogen into insoluble fibrin. These insoluble threads of fibrin form the clot. Both thrombin and fibrinogen are produced in the liver. If fibrinogen is less than 4%, the process of blood clotting will be disturbed due to the production of insufficient threads of fibrin.
No, it's not B. The energy needed to "pump" sodium outside the cell in active transport is ATP. When ATP releases energy (for metabolism usage) during active transport, the sodium is discarded.
As humans sometimes experience, a cold environment can result in<span> </span>shivering<span>. This is when skeletal muscles begin to shake in small movements, creating warmth by expending energy. Humans can also sweat in high temperatures. The water on the surface of the skin is able to absorb a lot of heat during evaporation, resulting in cooling of the body.</span>
