Well, you don't specify the parent traits, so I'll just do one for each...
If both parents are homozygous RR, then all 60 of the babies will be black
If both parents are homozygous WW, then all 60 of the babies will be white
If both parents are heterozygous RW, then there will be 15 black babies, 15 white babies, and 30 spotted babies.
If one parent is homozygous RR and one is homozygous WW, then all of the babies will be spotted
If one parent is homozygous RR and one is heterozygous RW, then 30 of the babies will be black, and 30 will be spotted
If one parent is homozygous WW and one is heterozygous RW, then 30 of the babies will be white, and 30 will be spotted.
Answer: b. It only arrest growth of vegetative cells
Explanation: An antimicrobial agent is a substance that kills o control the growth of microorganisms, for humans this is very important in medicine or agriculture among others.
This agent should act quickly and being stable that help it to make it cheaper, also should not harm humans or other host of the microbial organisms.
The agent is not useful if only kills vegetative cells because it is not preventing the reproduction of the organism specially in fungi which use sexual reproduction as a backup for asexual cell division, so they will keep spreading across the host.

The "Spanish" influenza pandemic of 1918–1919, which caused ≈50 million deaths worldwide, remains an ominous warning to public health. Many questions about its origins, its unusual epidemiologic features, and the basis of its pathogenicity remain unanswered. The public health implications of the pandemic therefore remain in doubt even as we now grapple with the feared emergence of a pandemic caused by H5N1 or other virus. However, new information about the 1918 virus is emerging, for example, sequencing of the entire genome from archival autopsy tissues. But, the viral genome alone is unlikely to provide answers to some critical questions. Understanding the 1918 pandemic and its implications for future pandemics requires careful experimentation and in-depth historical analysis.
