Answer:
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.

Answer:
Bird irruption and climatic phenomena subsequently
Explanation:
The Hawaiian islands are extremely diverse in both flora and fauna species. Today, similarly to the Galapagos Islands, there are thousands of species of Hawaiian finches, some of them eat seeds, others fruit, while other nectar, etc. Also, their beaks and colors are incredibly variable.
After years of research, scientists determined that it was one finch progenitor that arrived from Asia to the Hawaiian Islands around 6 million years ago, which gave rise to this process of speciation. This situation, as suggested by the researchers, occured due to a phenomenon known as 'irruption', characterized by the movement of hundreds to thousands of birds from one region to another located very far.
This finch is suggested to have gotten carried away in a storm, which eventually brought it to the Hawaiian Islands.
Answer:
Embryo with single cotyledon
Explanation:
Monocot, also known as monocotyledonous plants are a group of flowering plants (angiosperms) that possess one seed-leaf or cotyledon, which is contrary to the two-seed leaves possessed by dicots. Monocot plants have other characteristics that differentiate them from dicots as follows:
- Their flower parts are in multiples of three.
- It's major leaf veins are reticulated
- Pollen with single furrow or pore
However, the embryo of monocots are with a single cotyledon.
