Reptile -lays eggs that can't be moved and breathes via air.
Fish -majority lays eggs and breathes via gills extracting oxygen from water.

The four traits used to determine which kingdom an animal belongs to are cell type (prokaryotic or eukaryotic), cell number (unicellular or multicellular), how they obtain energy (autotroph or heterotroph), and the way they reproduce (asexual or sexual).
life cycle
For the paramecium to move forward, its cilia beat on an angle, backward in unison. This means that the paramecium moves by spiralling through the water on an invisible axis. For the paramecium to move backward, the cilia simply beat forward on an angle in unison. If the paramecium runs into a solid object, the cilia changes its direction and beats forward, causing the paramecium to go backward. The paramecium turns slightly and goes forward again. If it runs into the solid object again it will repeat this process until it can get past the object
After the animals eat them, the seeds and the fruits will be in the stomach. The fruit gets digested but the seed cannot be digested. So when the animal goes and take a dump, the droppings left by the animal will be the fresh soil for the plant. and there goes another generation of another plant. :D
It is Kingdom then Domain in biological classification. The classification hierarchy starts with Kingdom, followed by Phylum, Class, Order, Family, Genus, and Species. Domain is a higher taxonomic rank that is placed above Kingdom.
In genetics, dominant traits are those that are expressed in an individual's phenotype when only one copy of the allele is present, while recessive traits require two copies of the allele to be expressed. Dominant alleles are represented by a capital letter (e.g., 'A'), while recessive alleles are represented by a lowercase letter (e.g., 'a'). The expression of dominant or recessive traits follows Mendel's laws of inheritance.
