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.

alexandr1967 [171]

Answer:

Angiosperm

Explanation:

The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.

It is least gene dense  as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.

How does a cell handle misfolded proteins
ANEK [815]
<span>Cells primarily recognize exposed hydrophobic patches when identifying misfolded proteins. This is very prevalent in bacteria and I would assume that similar mechanisms are used in eukaryotes. There is also a system where misfolded proteins are tagged by different glycosylation patterns, but I don't remember much about that part.</span>
