Answer:
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.
The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.

Explanation:
Cells are organized into tissues, which are then organized into organs, and are finally organized into organ systems.
Systems are composed of different organs working together to carry out a common function or purpose. For example, the stomach, pancreas, intestines, are organs that are part of the digestive system, which breaks down the food we eat to give nourishment to our body.
Similarly, organs are made up of similar tissues carrying out a common function, and tissues are made up of cells of the same kind or type, also carrying out a common function or purpose.
Answer:1Zn+2HCl------1ZnCl2+1H2
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
