Explanation:
The picture simply shows that after a period of 10 years, the population of the prairie dogs increased.
Carrying capacity can be described as the maximum number of individuals of a species that a particular habitat can hold. As the diagram shows, there are no factors showing that the carrying capacity of the particular habitat has increased. Hence, other statements like statement D is false.
Answer: Swimming
Explanation:
The swimming motility is one of the type of bacterial movement. This bacterial movement is mediated by the rotating flagella. It takes place when the individual cells move in the liquid environment.
The phase contrast microscope is used to the enhance the contrast of the images formed by the ordinary light microscope. This can be used for observing the transparent and colorless specimens. The phase contrast microscope enables the visualization of the cells and their organelles that would be difficult to observe under the ordinary light microscope.
The phase contrast microscope can also help in observing the swimming motility of the bacteria. This can be used to observe the change in directions of the bacilli under microscope.
The answer would be Arctic Hare
Subduction zone
Explanation:
The feature created at the convergent of two oceanic crust having the same density is a subduction zone.
A subduction zone is covergent margin in which two plates pulls together and one goes under the other.
- Oceanic crusts are denser than the mantle below,
- When convergent occurs between them, one of the two plates will simply go into the mantle.
- This results in the formation of a subduction zone.
