Guttation is the process of loss of water from the surface of leaves in the form of liquid drops... Guttation occurs when root pressure is high and transpiration is low.
The right answer for the question that is being asked and shown above is that: "a decreasing number of viable, fertile hybrids is produced over the course of generations." The phenomenon of fusion is likely to occur when, after a period of geographic isolation, two populations meet is that <span>a decreasing number of viable, fertile hybrids is produced over the course of generations.</span>
I think it changes the physical appearance of that certain trait. For example, eye color. If the proteins are set up a certain way for brown eyes, then changed, there would be blue eyes.
Answer:
D. The new technology allows the detection of a structure that could not be detected previously.
Explanation:
The theory is developed based on real things. But theory can be changed. No theory exists forever. Now, if a theory is developed in biology from exiting components of the cell, then if any new elements discovered in the cell, later the previous theory can be changed at any time. So, if any new technology arrives, which can detect the structure of a cell which wasn't found before, that causes change or modification of an existing theory.
