Answer: As the temperature increases, molecules move faster, then enzymes they speed up metabolism and cells rapidly increase in the size.
Explanation: do bacteria growth faster at a higher temperatures molecules move slower,and enzymes cannot mediate in chemical reactions,
Answer:
Option (2)
Explanation:
The earth is comprised of numerous species, and this diversification of species gradually increases from the polar region to the tropical region of earth. The tropical and equatorial region is comprised of different species as this region receives the maximum amount of energy, nutrients, sunlight and rainfall.
Some of the biologists often believe that the species diversity increases with the latitude. The higher latitudinal region are mostly covered with ice and glaciers. But without the occurrence of ice age in the past, there is still lesser but sufficient amount of energy that is available in the higher latitudinal region that can support different types of biome, comprising a significant number and variety of species.
Thus, the correct answer is option (2).
<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>
