Shaping. Each step in the learning process is called an approximation. An animal may be reinforced for each successive approximation toward the final goal of the desired trained behavior. Animals learn complex behaviors through shaping.
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor.
Sickle cell disease trait is passed on when one parent has a change in the a gene. when no the parents have a Chan g rd in the a gene then the chances of getting sickle cell disease is greater

- Sterilize equipment and materials.
- Disinfect work areas before and after use.
- Autoclave or disinfect all waste material.
- Never pipette by mouth.
- Clean up spills with care. Wash your hands.
What is Biological Safety Level (BSL):
