1. mother to fetus 2. through exposure to the antigen (virus, toxins, or cancer cells).
<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.

Hope this helps
False. They form a V formation so that it will lower their heart rate and make it easier to go longer distances. And when they are in a V formation, it results in wind resistance.
