The animal kingdom is unique among eukaryotic organisms because most animal tissues are bound together in an extracellular matrix by a triple helix of protein known as collagen. Plant and fungal cells are bound together in tissues or aggregations by other molecules, such as pectin.
Explanation:
The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it's a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.
Celiac disease is a type of an immune disorder in which a person is unable to eat food that contains gluten because it can lead to the destruction of their small intestine.
Gluten is a type of protein that is found in several ingredients such as wheat, rye, and barley.
Consumption of gluten can lead to the development of inflammation in the small intestine which after a certain time can lead to its destruction.
The various symptoms associated with the disease include bloating, diarrhea, anemia, etc.
Since Carlos has celiac disease he has to avoid wheat, rye, and barley.
Summary. Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
