Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
The answer to the question is D
The role of mass extinction in evolution. At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendant species they might have given rise to. ... But mass extinction can also play a creative role in evolution, stimulating the growth of other branches.
Answer:
Throughout the experiment at hand, the student will likely find that root space does indeed effect the length to which plantswill grow. Although I could not locate the table online, I will offer a general hypothesis for what the experiment will conclude. The student is testing the effects of root space on the way plants grow. The students experiment is well designed, keeping many variables constant and making sure that the amount of root spaceis the only difference between the plantsensures the accuracy of the experiment. Since we know that the experiment is well designed we are able to directly infer the effects of root space limitations without having to account for other factors. We can assume that the limited root space will in turn limit the extent to which a plant can grow. This is because plants need larger and deeper roots to support extended growth. Therefore, the plants in group Bwill grow smaller than those in group A.
