Answer:
bacteria
Explanation:
This bacteria includes Nitro cocci, nitrobacter and nitrospina
There are basically three types of evolution divergent, convergent and parallel evolution.
a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
The answer to your question is Passive Transport.
Answer:
This is because a single species of potato plant was predominantly cultivated at a time by farmers on the same farmland year in-year out in ireland in the 1800.This is monoculture.
One of the disadvantages of this practice is lack of genetic variation, which reduces the resistance of these plant to potato blight.
Lack of genetic diversity made the same gene to be inherited by all the potatoes and therefore no room for a resistant gene which might have provided resistance gene, through variation thus all the potatoes with the same weak resistant genes were exposed to the same<em> phytophtora infestant</em> which caused rotten .
This is an example of genetic diversity and its importance in diseases protection.
Answer:
Antibiotic resistance
Explanation:
Antibiotic resistance will become a major public health threat. It is believed that the flow of some salmonella clones from farm animals treated with antibiotics to humans through food products, will make us contract salmonellosis. This will be difficult to cure due to resistance to antibiotics.
