Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.
Answer:
Option B, by saltation in the first few meters above the land surface
Explanation:
In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift & drag force and characteristics of wind such as velocity and turbulence.
Hence, option B is correct
If you're referring to what a group of zebras is called. Its very interesting, a group of zebras is called a Dazzle or a Zeal!
