Unmanned marine vehicles are useful because they help with marine tasks, completing them in less time, reducing risks, reaching deeper areas.
Unmanned marine vehicles (UMV) are robotic vehicles controlled from afar that allow us to explore the sea and perform tasks with minimum risks.
UMV is useful because:
- They substitute people working at the sea in risky tasks,
- They allow deeper exploration of the sea.
- They do tasks in less time than humans.
An example of how useful these marine vehicles are is during the construction of ports. They replace divers who have to do the job manually, spending many hours and risking their lives. With a UMV, there is no need for humans to go under the water, experts control the robot from the surface.
In conclusion, UMVs are useful because they are practical tools that save time and reduce risks.

A vaccine is a medical product. Vaccines, though they are designed to protect from disease, can cause side effects, just as any medication can. When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes. Most viral mutations have little to no impact on the virus’s ability to cause infections and disease.
There are several evidences of evolution, some that we have greater knowledge and others we don't, but in this question all alternatives contain evidence of evolution, to understand better we need to know that.......
<h3>Fossil Evidence</h3>
Fossils are remains or traces of preserved organisms that are more than 10,000 years old and provide important information about life in past times and what the environment was like at a given time.
- Bones
- Teeth mark
- Footprints
- and petrified feces are examples of fossils.
<h3> Comparative embryology and Homologous structures</h3>
Some species have anatomical characteristics that are very similar to those present in individuals of other species. Although these structures often do not have the same function, it is possible to infer that, at some point, these species had a common ancestor.
<h3>Biochemistry and Metabolism</h3>
The analysis of cells and the biochemistry of organisms have revealed that there is much similarity between all living beings. This fact suggests that, at some point in evolutionary history, we had a common ancestor.
It can be seen, therefore, that the theory of evolution is supported by several pillars and every day it is more evident that living beings undergo changes over time.
With this information, we conclude that <u>all alternatives are evidence of evolution.</u>
