Which of the following is a correct statement about genes and traits?
Genes code for proteins that determine traits.
Which chromosome is the HFE gene associated with?
Chromosome 19
What is the relationship between alleles and genes?
Alleles are different sequences of the same gene.
What is the main idea behind the concept of fitness tradeoffs?
Organisms need to make a tradeoff between reproduction and immune response due to limited energy.
What is acclimatization/acclimation?
A phenotypic change that occurs in an individual in response to environmental fluctuations.

Which of the following best describes adaptation in biology?
A heritable trait that increases an individual's likelihood of survival and reproduction in a specific environment
What is the difference between adaptation and acclimatization?
Adaptation is a genetic change, while acclimatization is a non-genetic change

Which one of these is true about myosin and actin?
Myosin is responsible for sliding the actin filaments during contraction.
Which one of these is true about the breast muscles of birds?
The breast muscles of birds are responsible for the contraction and relaxation of the muscles that flap wings.
