A contractile unit of fibers
Where are sarcomeres located?
Skeletal muscle
Thick filaments:
Myosin
Thin filaments:
Actin

The depolarization of a neuron leads to an action potential.
What builds bone?
Osteoblasts
What breaks down bone?
Osteoclasts
How does the process of bone reformation occur?
Inorganic ions are absorbed through the blood for use in bones.
Bone degradation is also called
Reabsorption
When degradation occurs:
Inorganic ions are released into the blood.
Stable Hardy-Weinberg equilibrium mean that the population has which characteristics?
No mutations, large population, random mating, no net migration, and equal reproductive success.
p squared is:
The frequency of dominant homozygotes
q is:
Frequency of recessive allele.
2pq is:
Frequency of heterozygotes
q squared is:
Frequency of recessive homozygotes.
