Answer:
the life chain of a particular animal
Answer: Resistance
Explanation:
Bacteria are single cell microbes that can be found in plant cells, animal, human body...They could be beneficial some are use for fermentation or harmful.
Over time, Bacterial have shown resistance and virulent to man by gaining resistance to antibiotics use to destroy there adverse effect in human system.
Some bacteria such as mycobacterium gonorrhoeae that causes gonorrhoea has shown medium resistance to antibiotics
Acinetobacter Baumannii causing pneumonia has shown a high level of resistance towards antibiotics making it difficult to reduce there effect. This has lead to more research on how this bacterial will be less virulent and harmful to man
Answer:
By the use of uncontaminated water
Explanation:
Blood flukes are flatworms that are parasitic in nature. These are also called schistosomes.
If we consider the mode of transmission of the parasites to humans, we find that their transmission occurs in the following conditions -
- These parasites enter the human body when a person is swimming in contaminated water.
- They can also infect the human body if the person drinks contaminated water or eats food that have been washed with the contaminated water.
Thus it becomes clear that contaminated water is the main source of infection of blood flukes so using uncontaminated water and avoiding to be in contact with contaminated water will reduce the incidence of blood flukes in human population.
As populations are the smallest unit that actually evolves, it is reasonable to call them the "unit of evolution"
