Answer:
survive in their environment
Explanation:
According to Darwin's theory of evolution, natural selection is the main mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
Answer : Binary Fission which grows exponentially.
Explanation : Binary fission actually means binary - consisting two and fission - cleavage into halves. It is one of the modes of asexual reproduction.
This type of fission is majorly observed in the asexual reproduction in prokaryotes. It is rarely seen in some some single-celled Eukaryotes like Amoeba and Paramecium.
Also, In binary fission there is DNA replication and segregation which occurs simultaneously.
This increases the graph exponentially as the growth gets faster and faster with the passing period of time.
A reference image of binary fission is attached in the answer.
Answer:
The likely cause is pathogenic bacteria.
Explanation:
The pathogenic bacteria are bacteria that cause food poisoning through the contamination of food by faeces. Examples include Salmonella typhi, E. coli, Clostridium botulinum e.t.c.
This means that they are contacted through faecal oral route.
