Organisms are made up of a bunch of cells. Billions of cells coming together make up an organism.
A dominant allele can produce a dominant phenotype in individuals with one copy of the allele from one or both parents, but a for recessive allele to produce a recessive phenotype, the individual needs to have two copies, one from each parent.
It is found in the cell walls of plants.
The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.
Species evolve from pre-existing species
