Answer:
Explanation:
Science (genetics, molecular biology, genomics) genes or gene products that are homologous (descended from a common ancestor) and are found in separate species due only to the speciation event (not to gene duplication).
Answer:
more cell types are needed to perform specialized functions in multicellular organisms
Explanation:
Cells in a multicellular organism differentiate to produce more cells that perform specialized functions. Each cell type in a multicellular organism has special features that enable it to perform a particular function effectively. In plants, cell differentiation occurs at the stem and root. The meristematic cells differentiate into either an epidermal, parenchymal or a vascular tissue depending on location.
Hello!
The continental drift says that the world was made up of a single continent, now divided by the plate-tectonics movement. The plate-tectonics, so, explains how the continents are drifting.
Hugs!
DNA is made of chemical building blocks called nucleotides
