Answer:
a) properties of the molecule as a result of abnormal interactions between adjacent hemoglobin molecules
Explanation:
In sickle cell disease, for example, a nonpolar amino acid (valine) replaces a polar amino acid (glutamate). This substitution of amino acids reduces the hemoglobin’s water solubility. The mutated hemoglobin molecules form long, stiff and rod-like crystals inside red blood cells which are otherwise not formed by normal hemoglobin molecules.
These abnormal crystals of hemoglobin cause the deformation of RBCs making them sickle-shaped that cannot properly squeeze through narrow blood vessels. Therefore, the substitution of single amino acid results in abnormal interaction of two or more hemoglobin molecules that are not exhibited by normal hemoglobin molecules.
Explanation:
Plant) Banana
Trait: Smaller seeds, larger fruit, thinner skin
People breed plants to gain desired produce with more yield. After years of genetic nurturing, the perfect bananas were created with smaller seeds, larger sizes, and an offspring with greater abundance for maximum profit.
Animal) Chihuahua
Trait: Smaller size
Chihuahuas are a great example of artificial selection in a domesticated animal because over time people successfully breaded different dogs to acquire the size of the chihuahua.
