a large class of molecules made of amino acids...since amino acids are the smallest particles that make up proteins.
I hope this helps
Answer:
Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

Answer:
c, sickle cell anemia
Explanation:
When you are conceived you (generally) receive one set of chromosomes from your mom and one from your dad. Recessive diseases mean that you must receive 2 copies of the mutated gene (disease gene) to express the disease (one from mom and one from dad). Dominant means that you only need one copy of the mutated gene to express the disease.
Sickle cell anemia is a disease caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. The mutation is on an autosome (not a sex chromosome). You need two copies of the bad gene in order to express it.
