Answer:
Although these two animals are both bears, clearly they are entirely different. Becasue they live in pretty much opposite environments, they developed individual traits so they could survive, which is called adaption. While the polar bear's thick fur and fat serve as great protection against the cold, it wouldn't be very helpful in hot climates. And the sun bear, with it's short hair and lack of protection, would freeze to death in the polar bear's environment. Each animal, over time, has to develop new traits that allow it to adapt to it's particular environment.
Answer:
Collagen fibers
Explanation:
Cartilage is the connective tissue found in the mammalian group of animals and is composed of the collagen fibre made by the chondrocytes which occur at the scattered sites.
The fibrocartilage is one of the types of cartilage present in the intervertebral disks and helps provide the tensile strength and help absorb the shock in the spine.
The extracellular matrix of fibrocartilage is enriched with the collagen fibres which provides toughness and great tensile strength to the cartilage.
Thus, Collagen fibres are the correct answer.
That is exactly what binary fission means
Answer:
A major factor in determining the mode of nitrogen excretion is the availability of water in the environment. Generally, aquatic animals excrete mostly ammonia, whereas terrestrial animals excrete either urea or uric acid.
