According to this dichotomous key, any catfish must be leathery, that is, without scales. They have a flattened body, as in most fish with benthic habits, that is, they live at the bottom of the waters. Coloration varies from bluish gray to yellow. It can reach 1 meter in length and weigh about 5 kilos.

<h3>What is catfish?</h3>

Catfish and catfish are common designations given to fish of the order Siluriformes in most of South America.About 2,200 species of these fish are known, classified into almost 40 families (only two, Ariidae and Plotosidae, have marine species). They are found almost all over the world, but more than half of the known species are native to South America.

With this information, we can conclude that the catfish (Ictaluruspunctatus) is a representative fish of the order Siluriformes, family Ictaluridae, characterized by not having scales.

What makes a tunicate more complicated than a sea sponge?
Umnica [9.8K]

Given what we know, we can confirm that in summary, what makes a tunicate more complicated than a sea sponge is cellular differentiation.

<h3>What is cellular differentiation?</h3>

This is what we call the cells ability to specialize itself into a specific cell type. Some examples of this in humans include:

  • Heart cells
  • Digestive cells
  • Reproductive cells
  • etc.

Due to this, tunicates have evolved different tissues, organs, and complete cell types, making them much more complicated organisms than sea sponges.

Therefore, we can confirm that due to the multiple tissues, organs, and systems developed through cellular differentiation, tunicates have become more complicated than sea sponges.

Which term specifically describes the categorization of people into ethnic groups without taking into account individual differe
zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.
