The scientist that presented that deoxyribonucleic acid contained equal quantities of certain nitrogen bases is Chargaff. In addition, Chargaff’s rules state that deoxyribonucleic acid from any cell of all organisms must have a 1:1 ratio which is base pair rule of pyrimidine and purine bases and more precisely that the total of guanine is equal to cytosine and the total of adenine is equal to thymine. This configuration is found in together strands of the deoxyribonucleic acid.
<em>Rocks erode and sediment is deposited, and No sediment is deposited over a long time.</em>
<u>Explanation:</u>
The most common reason for the formation of <em>uncomformity is erosion</em>. The <em>times of formation of the rocks</em> above and below the uncomformity are different when no sediment is deposited over a long time.
The rock above the uncomformity are younger than the rocks below the uncomformity. Types of uncomformity are <em>angular uncomformity, discomformity and non comformity.</em>
In angular discomformity horizontal sedimentary rock layers are formed above sedimentary rock layers that are in tilted position. Discomformity lies between two <em>horizontal sedimentary rock layers</em>. Non comformity lies between<em> sedimentary and igneous rock layers or metamorphic rocks.</em>
Answer:

Mucus, saliva, would be natural barriers to infection.
Newborns are much better protected against (or immune to) potential illnesses and diseases than you might otherwise think. This is because during pregnancy, disease-fighting antibodies made in the mother’s immune system are able to make their way across the placenta and into her baby’s body. Fortunately, these antibodies stick around for several months and are able to give newborns an added level of protection from many routine illnesses during this important time when they are not as able to effectively make their own antibodies.
