Answer:
Yes...This is an example of speciation by natural selection
Explanation:
As we know that natural selection always promote those evolutionary changes that are necessary. Changes that happen in chromosome number always promote with a specie that is closely related to the parent specie and produce fertile off-springs. These new generations are most adaptable and can survive in the environment more efficiently than the previous ones.
Additionally, other than natural selection, speciation can also happen as a result of random mutations, genetic drift and by means of artificial selection as well. But the natural likelihood of all these is probably low as compared to that of natural selection.
Answer: Fungus like protists are heterotrophic and feed on organic matter.
Cellular slime mould is a species of fungus like protists that form slug.
Explanation:
Fungus like protists are heterotrophic and the feed on organic matter and mostly unicellular.
Cellular slime mould are protists belonging to class Dictyostelia. They are heterotrophic and decomposers that live on organic matter. When there is deterioration condition, the cells migrates together to form slugs and move to form new habitat. Some of the cells form stalk and others form spores.

Answer:
Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the PELAGIC zone. To view shorebirds and crabs, Hilda should move towards the INTERTIDAL zone.
Explanation:
The Pelagic Zone
It is any water in an ocean or lake that can not be said to be positioned in proximity to the shore or in proximity to the bottom (the shore and the bottom are two distinct zones with a completely different properties.
Divisions of the Pelagic Zone
It can be grouped into subzones based on depth, we have the epipelagic, close to the top of the zone which as light been present, and the abyssopelagic, is nearer to the bottom with light being absent.
The intertidal zone
Its found between the high tide (upper limit) and low tide lines (lower limit), majorly on the beach at the water's edge.
The major attribute of the intertidal zone is that it is immersed with water at high tide and is in exposure to the air at lower limit. The intertidal zone is usually undergoing alterations leading to organisms that are uniquely adapted to strive there.
Organisms found in this zone are sea stars, crabs, mussels, barnacles, and various corals as they well situated to strive immersed in water and a region of their lives open air at lower limit.
Because some problems are not always small enough for one nation that can do it by themselves and need more helpo
