Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
Answer:
True
Explanation:
Pioneer organisms are the first organisms that reoccupy a region that was destroyed by a disaster like flood, forest fire, volcanic eruptions, etc. These pioneer species can grow in the habitat that is barren and is not suitable for the growth and survival of other species.
Some of the pioneer species are lichens and algae. Pioneer species like lichens help in the formation of soil from breakdown or rocks which allow the formation of a suitable environment for the ecological succession of other species like mosses, algae, and other small plants. Therefore the statement is true.
One of the threadlike processes forming the respiratory surface of a gill.
