from other animals they get it
because structural characteristic do not change over time but physical appearance do
Scientists classify sponges based on their body structure, specifically the presence of pores through which water flows for feeding and gas exchange. Additionally, they consider the type of skeleton sponges have, whether it's made of calcium carbonate, silica, or spongin fibers.
their genome
The chart is a dichotomous key. It helps them classify things.
they use genus and dichotomous keys
Scientists classify organisms by the dichotomous key. They classify by looking at if it moves or not, then they look at characteristics, then they can see what they are.
scientists classify organisms into groups based on internal and external features.
DNA is the answer.
by the way they look and act
Scientists use the periodic table to classify the elements. The elements are arranged in the table based on their atomic number, electron configuration, and chemical properties. This organization helps scientists identify patterns and relationships among the elements.
Scientists use color, size, brightness, and temperature to classify stars.
