Predicting how and when the storm will occur(hypothesis), observing the storms patterns(observation), and concluding what happened with the storm(conclusion)
Answer:
The correct answer: C) allows the behavior of microtubules called dynamic instability.
Explanation:
Microtubules are structures that are part of the cytoskeleton and help provide structure and shape to eukaryotic cells, besides assisting in the transport of organelles and vesicles.
Microtubules are formed by the polymerization of a dimer of two tubulins.
Microtubules have the particularity of being able to easily assemble and disassemble, which enlarges and shrinks the microtubule respectively. This property of the microtubules is important to their functions and is called dynamic instability.
In order to achieve dynamic instability, tubulin dimers can bind two molecules of GTP - for polymerization to happen, one of the GTP molecules is hydrolyzed to catalyze the reaction, thus becoming GDP. In the same matter, the energy generated from the depolymerization with turn the GDP into GTP.
Hi
Before answering the question, we need to understand what homologous organs are?
These are basically different organs that are found in different animals which apparently look different however they have similar anatomical structure. These are called homologous organs and they are an excellent source that shed the light on evolution of different organisms.
Homologous organs of three animals:
1: Dolphin's flipper
2: A bird's wing
3: Human arm
Although these are three different organs of three different organisms but still they are homologous organs, this is because the anatomical features of these structures suggest that these have similar sort of arrangement of bones, and wing sub parts. This suggests that in past, all these three organisms have a common ancestor and later due to evolution, they evolved into new creatures.
Hope it helps!
