D. It's harder body parts. A lot of fossils are of the skull, therefore that would lead one to think that it would be harder<span />
Essentially wetlands<span> are the transition </span>between<span> dry land and water (streams, </span>rivers,lakes<span>, and coastlines), </span>wetlands<span> take many forms including the familiar marshes, swamps and bogs. Yet, not all </span>wetlands<span> are "wet" year round. These "drier end"</span>wetlands<span> also perform significant </span>wetland<span> functions.
Hope i helped :)</span>
The right option is; c. a salinity of less than 1%
Freshwater biomes have a salinity of less than 1%
The freshwater biome is a large community of plant and animals that live in water bodies with a salinity of less than 1%. Fresh water biomes include streams, rivers, ponds, lakes, and some wetlands. The fresh water biomes cover about 20% of the earth and they contain several species of fish and animals such as frogs, crocodiles and turtles.
