Answer:
Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>
Explanation:
MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.
For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
Answer: Male red-winkled black birds defending limited nesting sites from other males.
Explanation: Intraspecific competition is defined as a competition between two individuals from the same species. There are two types of intraspecific competition which are interference intraspecific competition and exploitation intraspecific competition. For the purpose of the answer provided above, interference intraspecific competition is discussed.
In interference intraspecific competition, the species establish hierarchies through aggressive behavior in which one or more individuals within the population holds a dominant status over the others. These individuals limit or prevent access of more subordinate individuals to a resources through direct interactions.
Here, only those individuals who are dominant or holds territories will increase their production success. Example of this is in when two winkled black birds establishes a territory of nesting sites, thus limits the access of this nesting sites thereby defending the nesting sites from other males.
