Answer: b
Explanation:
An open system is when nutrients and waste are moved through the body freely through the body cavity, rather than being enclosed in veins.
Fast-glycolytic muscle fibers are another name for Type IIb skeletal muscle fibers and are white in color. The skeletal muscle fibers are divided into three types: Slow-contracting muscle fiber (Type I), Fast-contracting muscle fiber (Type IIa) and Fast-contracting muscle fiber (Type IIb).
Fast-glycolytic muscle fibers Type IIb are abundant in muscles of the lower limbs that contract quickly and are oxygen dependent, prevalant in postural muscle of the back, generate lots of power and depend on lots of power and depend on anaerobic pathways to make ATP , have fewer but larger myofilaments and numerous mitochondria, have abundant myoglobin.
The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
ANSWER: C). Chlorophyll and carotenoids
If you have just eaten, your body will secrete insulin. Insulin is the hormone that allows glucose to enter cells. That way they will have the proper energy for their normal functions.
If you have not eaten for a while, your body is running out of glucose to feed the cells so it needs to secrete another hormone called glucagon. This hormone is the complete opposite of insulin because it breaks down glycogen, proteins and fats into glucose.
