Answer
similar characters evolved owing to convergent evolution; similar characters are ancestral
Explanation:
Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar. The analogous structures were not present in the known ancestors of both groups.
Therefore convergent evolution is ignored during constructing phylogenies
Also similar characteristics that are ancestral are ignored.
A gated channel allows the specific type of molecule or ion individually. Hope this helped!
Answer:
Photosynthesis is a process in which energy is produced in the plants with the help of sunlight. In photosynthesis, carbondioxide react with water forming oxygen and food material in the form of glucose. It occurs only in plants.
Respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules with the help of oxygen produces water, carbondioxide and energy in the form of Adenine tri phosphate (ATP). It occurs in all living organisms.
Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.
The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.
At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.
Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.
