A microscope is an instrument used in Biology which is used to see organisms that are not possible to be seen by the naked eye. Through advancement, from 2-D images, 3-D images are already obtained from microscopes including scanning-electron microscope and digital microscope.
Reproduction is not essential for the survival of an individual organism. However, it is essential for the continuation of an organism's species. A species is a group of similar-looking organisms that can Page 3 interbreed and produce fertile offspring
Streamlined bodies for swimming?
Well, bacteria is a decomposer
which means it will Break down dead organisms to its lowest component so it could be easier to recycled
not only that, it also convert atmospheric nitrogen so it could be used to maintain soil's fertility
hope this helps
The evolution of H. floresiensis is an example of island dwarfism.
Explanation:
H. floresiensis is a species of hominid. It differs significantly than the other hominid species in size though, as it appears to be a dwarfed version of its ancestors and close relatives. Its alleged ancestor is literary twice taller, which brings in the question as to what has triggered such an evolutionary adaptation.
This hominid species lived only on a relatively small island, in isolation. The resources are very limited, and the climate is warm and humid all year around. As seen in many species of animals, when individuals get into such an environment, they tend to experience either island dwarfism, or island gigantism. The island dwarfism tends to be common among large and medium sized species, while the island gigantism tends to be more common among the small species.
When the ancestors of H. floresiensis ended up in this environment, it was advantageous for them to smaller. The reason for that is that smaller bodies require less nutrition, and are also producing less heat.
