a rex was dumb that a spinosaurus could kill it is all i can say.
They make their own energy.
When scientists group living things, it is called taxonomy. Taxonomy is the branch of science that deals with the classification and naming of living organisms based on shared characteristics.
The classification of living organisms is known as taxonomy. It involves categorizing organisms into hierarchical groups based on shared characteristics.
In a way, yes. Since we know now that the closest living relatives to dinosaurs were the birds, it's likely that they shared many characteristics. We don't know for sure, but it's likely that males would flaunt their bright colors and feathers in the mating season, either impressing females or intimidating other males.
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Living cells also contain DNA and RNA. These are the only thing shared by living cells and viruses.
A scientific name consists of two parts: the genus name (which is shared with closely related species) and the species name (which is unique to the specific organism). By examining the scientific name, scientists can determine the evolutionary relationships between different species based on their shared genus name. This system of binomial nomenclature helps organize and classify living things based on their genetic and evolutionary relationships.
Present-day taxonomists attempt to group organisms according to their evolutionary relationships, genetic similarities, and shared characteristics. This helps to organize and classify living organisms into hierarchical categories based on their shared ancestry and unique characteristics.
