Answer:
The correct answer would be a. Fragments of DNA that have desired genes are isolated to form recombination DNA for use in a host. Genetic engineering refers to the direct manipulation or modification of the desired gene in a cell in order to produce novel or improved organism.
Explanation:
The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
<h3 /><h3>What is a random mutation?</h3>
Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.
Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

Answer:
Angiosperms
Explanation:
As per the evolution of plants the order is moss (Bryophytes), fern (Pteridophytes), Gymnosperm, and Angiosperm. Bryophytes are the most basic plant with only the capability of photosynthesis. Pterdophytes are an upgrade with being able to transport water and nuterients from the ground into vascular tissue. Gymnosperms and Angiosperms both are seeding plants , but angiosperms use flowers to reproduce.
