Explanation:
To make sure that the hypothesis is correct.
Answer:
c. Grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
Explanation:
This question depicts SECONDARY SUCCESSION, which is one of the two types of ecological successions where an area previously occupied by living organisms is disturbed by natural causes such as hurricanes, tornadoes etc. This is the case in this question where thunderstorms that lead to tornadoes leave a significant impact on the environment of the southeastern part of the United States.
According to the question, the tornado results in the uprooting of previously existing trees that has occupied that area. After the devastating effect of the tornado on the environment, changes occur rapidly since the soil of the environment are already rich in nutrients. The first plants to recolonize in secondary succession are annual plants consisting of grasses and shrubs whose seeds were not destroyed by the tornado. These forms of plants can also be called PIONEER species as far as secondary succession is concerned.
Hence, based on the question, grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
Answer:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition antibiotics are designed to have a significant destructive effects on the mechanisms of biochemical reactions in bacteria and its physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
