Embryology provides evidence for evolution because during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.
Genotype frequency: RR is dominant, Rr is heterozygous and rr is recessive.
R^2+2Rr+r^2 = 1
R = 0.85
R^2= 0.85*0.85 = 0.7225
Dr. Charles is using fMRI when she uses strong magnets to track changes in the brain's blood-oxygen levels.
Functional magnetic resonance imaging or (fMRI) is a techique used to measure brain activity by detecting changes associated with blood flow. When an area of the brain is in use, blood flow to that region will increase.
Answer:
The chemical structure of a saturated fatty acid exhibits each carbon bonding to the adjacent carbon with single bonds. Each carbon is also bonded to two hydrogen atoms. The linear nature of saturated fatty acids allows for tightly packed formations, causing them to be solid at room temperature
