Answer: Glycolysis
Explanation:
Glycolysis is an universal process which takes place in all the organism from bacteria to humans. It can occur whether oxygen is present or not. It is the first step of cellular respiration that takes place in cytosol.
During glycolysis, breakdown of the glucose into pyruvate occurs with the formation of two energy molecules of ATP and two NADH molecules.
Thus, the correct answer is option (A).
Answer: C. The farmland is undergoing secondary succession, which may or may not restore the original climax community.
Explanation:
Ecological communities are highly <em>dynamic</em>- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a <em>climax community. </em>While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
Like the abandoned farmland near Horatio’s home, secondary communities do not begin with the removal of soil and all biological life; other species, seen here in the grassland, may be more suited to the altered conditions and begin to modify the area creating a new community.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.
Answer:
Explanation:
The correct match is given below:
1. Communicable by direct acquisition via vertical transmission. C. <em>Treponema palladium</em> (syphilis).
2. Communicable by indirect transmission via air droplets. B. Tuberculosis
3. Communicable by direct transmission via a biological vector. F. Malaria
4. Non-communicable. A. <em>Clostridium tetani </em>(tetanus).
5. Communicable by indirect transmission via fomites. D. <em>Staphylococcus aureus</em>.
A because everything is fueled because of it. It does not consume or hunt anything.
