Answer:
- Ecological levels to consider in this study: organism, population and community
- Approach: I would use an observational approach to study this bird species
Explanation:
The levels of the ecological organization include the organism, population, community, ecosystem, and biosphere (from simplest to most complex). In this exploratory study, it is imperative to consider: 1-morphological, physiological and behavioral adaptations of the bird species (i.e., organismal-level), 2- size/density/structure of the bird population (i.e., population-level), and 3-interactions between bird population and other populations (i.e., community-level). The higher ecological levels, i.e., ecosystem-level (relationships between the community and abiotic factors ) and biosphere-level (biosphere = planet Earth), can be in this case disregarded because this study is centered on a focus bird species. Moreover, it is expected to apply an observational strategy because nothing is currently known about the focus bird species. The experimental and modeling approaches seem more suitable to test a particular hypothesis being discussed (it is not the case for this study).

Answer:
False
Explanation:
Annelids are actually more closely related to species within the mollusk phylum than they are to their worm cousins in the flatworm and roundworm phyla. Although they look quite different on the outside, mollusks and annelids share a more recent common ancestor than roundworms and annelids.
Answer:
Low mean corpuscular value can shift the curve to the left side.
Explanation:
RBC histogram may be defined as the process of plotting the number of blood cells on Y- axis and their relative size on X- axis. Modern automated haematology is used for the construction of RBC histogram.
The cell population of RBCs is similar in size but not equal to the size of RBC the curve can shift to either direction. The low MCV (mean corpuscular value) value can shift the the curve to the left side while considering an RBC histogram.
