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.
Answer:
Contraction is prevented
Explanation:
The sarcomere is the basic contratile unit of muscle i.e the unit responsible for contraction in the muscle and it consist of two main protein actin; which forms filaments involved in contraction and myosin; a motor protein responsible for contraction. Calcium interacts with these protein and in the absence of Ca, contraction is inhibited (sacromere with not be able to undergo contraction)
Answer:
One hypothesis would be "The inheritance of one trait does not affect the inheritance of another trait".
It can be explained with the help of law of independent assortment.
It states that the genes are randomly distributed in the gametes, that is, independent of each other.
Experimentally it can be tested with the help of dihybrid cross.
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms
