Answer:
defines the problem to be explored
Specialization is what each cells personal function is, and differentiation is how one cell is different from another in any way
1. tiny sacs within the lungs which increase the surface available for gas exchange = alveoli
2. a digestive enzyme that breaks down starches and glycogen into sugars = amylase
3. the two thin-walled chambers that receive blood into the heart from the veins = atria
4. the two tubes into which the trachea divide to go into each lung
= primary bronchi
5. a tiny vessel through which diffusion takes place between the blood and the body tissues
= capillary
6. a mass of nerve tissue not part of the brain = ganglion
Answer:
Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.
Explanation:
Options for this question are:
- <em>They both lack a nucleus and contain cytoplasm.
</em>
- <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations. </em>
- <em>
They both evolved in the same geological time period.
</em>
- <em>
</em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria.
</em>
- <em>
They both have membrane-bound organelles.
</em>
- <em>
Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>
Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.
The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.
