This is an example of competitive exclusion. Over many generations, Gentoo penguins in another area adapt to feed on krill at greater depths than the Chinstrap penguins. This is an example of adaptive radiation.
Competitive exclusion is a principle in ecology that states that two species that occupy the same niche cannot coexist indefinitely. If one species is better adapted to the environment and has a competitive advantage over the other, it will outcompete the other species and drive it to extinction. This is what appears to have happened in the case of the Chinstrap and Gentoo penguins. These two species occupy the same area and have the same food source, which means that they are competing for the same resources. Over many generations, the Chinstrap penguins, which are better adapted to the environment, were able to outcompete the Gentoo penguins and drive them to local extinction. Adaptive radiation, on the other hand, is the evolution of a single species into multiple species that each occupy a different niche. In the case of the Gentoo penguins, it appears that they were able to adapt to feeding on krill at greater depths than the Chinstrap penguins. This allowed them to occupy a different niche and coexist with the Chinstrap penguins without competing for the same resources. Adaptive radiation can occur when a species colonizes a new area with a variety of available niches or when a species evolves to exploit a new resource. In both cases, the species is able to diversify and occupy a variety of niches, allowing it to coexist with other species that occupy different niches.

An experimental pharmaceutical is typically approved after it passes 4 phase of clinical trials.
What is clinical trial ?
Clinical trials are combination of new research, studies and experiments performed in people to evaluate the effectiveness of new experiment on human health.
It consists of main 4 phases.
Phase 4 clinical trial is also known as " Post-Approval Research and Monitoring ". It is the final stage of trial for any pharmaceutical product, drug or device. This trial study about the side effects, real life scenarios, long-term risks and benefits of particular pharmaceutical product which were not seen in the early trials.
So we can sayan experimental pharmaceutical can be approved when it passes 4 phases of clinical trials.

Answer:
A. cnidarians
Explanation:
Comb jellies are most closely related to Cnidarians. Cnidarians are marine invertebrate organisms which make use of their cnidocytes filled with tentacles in catching preys.
They also have body parts such as the ectoderm and endoderm and a characteristic middle jelly layer called the mesoglea which is similar in a comb jelly.
Examples of Cnidarians include sea anemones and corals.
Answer:
Transgenic organism:
Transgenic organism may be defined as the organisms whose genetic makeup has been modified by the molecular techniques. These transgenic organism are mainly produced in the laboratory for research work. The genes of one species can be modified or some other gene has been inserted in the organism.
Advantage of transgenic crop.
The transgenic crop has been produced by the genetic alteration of the crop. The main advantage of the transgenic crop is to develop the enhanced quality and quantity of crop. Vitamin rich golden rice has been produced by the transgenic crop.
