Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
The characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.
<h3>What do you mean by Transgenic organisms?</h3>
Transgenic organisms may be defined as an organism whose genome has been modified by the insertion of one or more foreign (non-self) DNA sequences from another species via artificial means.
A Plasmid is a circular DNA that assists in the insertion of foreign DNA sequences into the bacterial cell.
Therefore, the characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.
When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is 72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.
The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.

The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.
The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.
Example for a hot spot volcano is Mauna Loa on Hawaii.
