Answer:
Scenario I, Scenario II, and Scenario III are examples of competitive networks.
Explanation:
There are different examples of nets as interactions between species. Trophic net is a very common example of these interactions. Another one is the competitive network.
The competitive network refers to the competition for the same resource between different species in a community or ecosystem. When a resource is useful for two or more species, they compete to gain it.
The competitive network can be represented as arrows that indicate which is the dominant species over the other. This representation must be done with a<u> minimum of two species interacting</u> and indicating through the direction of the arrow, which species wins the competition.
There is a competitive hierarchy when there are more than two species, for example, species A, B, and C. Species A dominates over the other two, and species B dominates over species C. In these cases, the representation would be A --> B --> C. This reflects a transitive competitive network. Species A displaces species B and C, and species B displaces species C. The only species that can persist is A. This example can be extended to <u>any number of species</u>, which suggests that a hierarchy network does not promote biologic diversity.
The plant cells contains- cell wall, central vacuole
the animal cell have- cilia cetrosomes
Both plant cells and animal cells contains - cytoplasm and mitochondrion
The main structural differences between plant and animal cells are the additional structures found in pants. The structures include, the cell wall, the chloroplasts and also the vacuoles. The similarity between them is that they both contain plasma membrane, a nucleus, a nucleolus, mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus, peroxisomes and the microtubules.
Protein-energy malnutrition is a form of undernutrition caused by an extremely deficient intake of calories, protein, or both. Two examples of this type of malnutrition are kwashiokor and marasmus. Protein-energy malnutrition is more often caused by decreased absorption or abnormal metabolism. It is defined as a range of pathological conditions arising from coincident lack of protein and/or energy in varying proportions. The condition vary in forms ranging from mild through moderate to severe degrees.
