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.
Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)
There are choices for this question namely:
1. Sterile
2. Reproductive
3. Both
4. Neither
The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.
