Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells

Answer:
e. bacteria producing vitamin K
Explanation:
Microbial antagonism basically refers as microbes versus microbes i-e the indigenous microflora serve a beneficial role by preventing other microbes from becoming established in or colonizing a particular anatomic location in the body.
As all the options mentioned, refers to the microbial antagonism except option E as the normal microbes protect the host by : 
1) Producing acids.
2) Bactreocin production
3) By occupying the niches that the pathogens may occupy.
But the microbes cant compete with other microbes by  producing vitamins and growth factors that can be utilized by the host. 
Hence option E is the right answer.
