Answer:
Variation in gene leads to anatomical difference in the closely related species
Explanation:
Though some organisms are morphologically very different from each other, yet they can belong to same species group. It is because of shared genetic framework with minute changes.
For example – Human and chimpanzees have similar genes and share about 99 percent their genes with each other.
The variation in 1 % gene has led to visible anatomical differences such as varying lengths of arms, jaw structure and size etc.
The same is the case with six living species of mammals and their close relationship with dugongs and elephants
During El Niño, the jet stream is oriented from west to east across the southern portion of the United States, making the region more susceptible to severe weather outbreaks.
Protists are mostly unicellular organisms, whereas the fungi are mostly multicellular organisms. Molds are fungus-like giant structures. Protists can be either heterotrophs or autotrophs. Fungi contain a cell wall, which is made up of chitin.
