In zoology the sexual reproduction, the production of new organisms by the combination of genetic information of two individulas of different sexes.

Here are some of the major phyla of invertebrates: These phyla encompass a vast array of organisms with diverse forms, behaviors,…
The phylum chordata (animals with backbone)is divided into five common classes thats are: 1: Fish. 2:Amphibians. 3:Reptiles. 4:Mammals. 5:Birds. Fishes: 1: They live underwater. 2: They breath throughout gills. 3:Some of them have scales covering their bodies. 4:Fins help them to move under the water. 5:Cold-blooded animals. 6:They are born from egges.

The system of animal classification was developed by Swedish botanist Carolus (Carl) Linnaeus in the 1700s.Animals are divided into two groups on the basis of presence and absence of the backbone into: 1: Vertebrates 2:Invertebrtes. Vertebrates: These are a subphylum of chordates…
