Living organisms in any biome interact through a variety of relationships. Organisms compete for food, water, and other resources. Predators hunt their prey. Some organisms coexist in mutually beneficial relationships (symbiosis), while others harm organisms for their own benefit (parasitism). Still others benefit from a relationship that neither helps nor harms the other organism (commensalism).
Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and blackflies), and birds (ravens, snow buntings, falcons, loons, sandpipers, terns, and gulls). Reptiles and amphibians are absent because of the extremely cold temperatures. While many of the mammals have adaptations that enable them to survive the long cold winters and to breed and raise young quickly during the short summers, most birds and some mammals migrate south during the winter

Answer:
The correct answer is c. The client is using a Pyramid system.
Explanation:
The pyramidal method owes its name due to its structure: it is based on the gradual increase and decrease of the weight that we must ballast (if we require it in an exercise with ballast) or if we prefer it without additional weight, a gradual increase or decrease of the repetitions . All this increase and decrease in repetitions and / or weight, occurs in a staggered manner between each series for a single exercise, with the aim of being able to recruit a very high number of muscle fibers. It is usually done ascending or descending.
The descending pyramidal method consists of lowering the load, but increasing the repetitions, that is, it begins by applying large loads from the beginning and few repetitions, until ascending in the pyramid and completing the exercise having increased the repetitions and reducing the weight used. With this type, what we achieve is called the strength-resistance of the muscles.
Answer: Mammals give birth to live young, whereas the birth of amphibians takes place externally. Mammals are warm-blooded, while amphibians are cold-blooded. Mammals can live in all habitats, unlike amphibians, and have muted colors. Some amphibians can regenerate their limbs.
