1.Suppose you discover a fossil that is an impression
of an ancient organism. You observe that the organism did not have
any hard cell walls, but did seem to have muscular tissue. Explain
how each of these traits supports or does not support the
classification of the organism as an animal.
List at least three characteristics of organisms in the Domain Eukarya
The three characteristic features in domain eukarya are:
1. Double membrane bound nucleus
2. Membrane bound cell organelles
3. Sexual mode of reproduction at some stage of the life cycle.
4. Differentiation of tissues.
The characteristics of fossil does not have a cell wall but has muscular tissue. All the eukarya domain species doesn't have a cell wall. The kingdoms that have a cell wall are fungi and plantae and animalia kingdom species doesn't have a cell wall. The muscular tissue also is seen in animalia kingdom. Hence the fossil discovered falls under the animalia kingdom.
If you have any query kindly comment before giving thumbs up. Thank you.
