The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.
In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.
The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.
These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.

Answer: diffusion
Explanation:
Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.
This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .
Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.
It is also dependent on the size of the molecule
Answer:
1.Creating products, such as ethanol and enzymes.
2.Making drugs, such as antibiotics and vaccines.
3.Making biogas, such as methane.
4.Cleaning up oil spills and toxic wastes.
5.Killing plant pests.
6.Transferring normal genes to human cells in gene therapy.
7.bacteria help to break down food and keep you healthy.
Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods. The ecosystem relies on bacteria to function properly.
Hope this helps!!!!
