Defined as variation of life on Earth, biodiversity is the number and relative abundance of different species
Biodiversity is determined as the number of different species and the variation of their genetic material. If the number of species is high, then the biodiversity is also high. Area with high/rich biodiversity should be protected since it was home to many species. Using it for economical reason could lead to extinction of many creature.
Because since the species is isolated with its partners it has to find another way to multiply so it uses another animal to make a new species to stay alive
Only plants have chloroplast and a cell wall
Compared to arteries, valves have no pulse, have thin walls and have valves that prevent backflow of the blood. The pressure in the veins is less than that of the arteries, hence, there is no pulse. They are nearer to the surface of the skin. It also connects arteries and capillaries which transport blood all throughout the circulatory system.
