Which of the following best describes Recombinant DNA?
A. A bacterial plasmid with a target gene inside it.
B. A plasmid and restriction enzyme.
C. DNA that has been copied into an mRNA strand.
D. A bacterial gene with a target plasmid inside it.
The option that best describes Recombinant DNA is a bacterial plasmid with a target gene inside it. Thus, the correct option is A.
What is Recombinant DNA?Recombinant DNA may be defined as the methodology of adjoining DNA molecules from two different sources and inserting them into a host organism, to synthesize products for human use. It involves the principle of recombinant DNA technology.
DNA that has been copied into an mRNA strand is a normal process of transcription. A plasmid and restriction enzyme are the tools of recombinant DNA technology.
A bacterial gene never holds a target plasmid, while a bacterial plasmid always holds a target gene inside it.
Therefore, the option that best describes Recombinant DNA is a bacterial plasmid with a target gene inside it. Thus, the correct option is A.

Sea otter populations decreased with the addition of a predator.
D)
Sea otter populations increased as the producer level increased.
E)
Sea otter populations increased in the presence of an additional predator.
Answer:
B and C
Explanation
These are correct I did it in usatestprep.
Sea otter populations preyed upon fewer sea urchins. Sea otter populations decreased with the addition of a predator. Hence option B and C is correct.
What are predator?Predator is defined as an organism that mostly hunts and consumes other organisms for food. Predators have a significant impact on an ecosystem. By dispersing seeds and nutrients from foraging, they alter the ecosystems' structure. Carnivores, or animals that only consume other animals, include predators. Scavengers are predators that cannot always kill their own prey and are classified as predators.
The number of sea otters declined, the number of sea urchins increased, and the amount of kelp also decreased when orcas began eating sea otters in the kelp forest habitat. Because sea urchins eat kelp and sea otters eat sea urchins, this is the case.
Thus, sea otter populations preyed upon fewer sea urchins. Sea otter populations decreased with the addition of a predator. Hence option B and C is correct.

Vegetal coverage is very high and arranged in many different strata.
Vegetation is dominated by phanerophytes and epiphytes. These are evergreen plants with leathery leaf types, medium to small in size.

Answer:
Changes in DNA result in mutations, which may be beneficial, neutral, or deleterious to the organism. If these changes occur to DNA in sperm or egg cells, they could be passed onto the next generation. Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another.
