B. Between the grasses
C. In a dark hollow in a rainforest
D. In a shallow ocean lagoon
Answer:
The correct answer would be C: bacterial plasmids.
In plants, genetic transformation is usually achieved with the help of bacterial plasmid, especially Ti plasmid.
Ti plasmid is a tumor-inducing plasmid generally present in <em>Agrobacterium tumifaciens. </em>This bacteria has a natural ability to infect plant cells and caused tumors or crown gall disease in them. It is also known as natural genetic engineering of plants.
The modified or non-virulent Ti plasmid is used to transfer the gene of interest in the plants.
Answer:
Homologous structures are fully functional, show evidence of a common ancestor, and may or may not have the same function in different species
Explanation:
Homologous structures are structures that have arisen from a common ancestor. They might not look the same or perform the same function, but they have evolved from the same ancestor.
Examples include the forelimbs of vertebrates - think of the human forearm arm, bat's wing, horse's leg, and dolphin's fin. These all look very different and perform entirely different functions, but they evolved from a common ancestor.
