Microtubules are macromolecules that build both, cilia and flagella.
<span>Microtubules are cytoskeletal fibres that are formed by polymerization of α,β-tubulin and they are important components of cilia, flagella and some other cellular structures. Cilia and flagella are very similar in their organization, both have a central bundle of microtubules-axoneme. Axoneme is compound of nine outer doublet microtubules which surround a central pair of singlet microtubules. Even thought cilia and flagella are structurally similar, they are differentiated based on their function and/or length. Flagella are longer and the primary role of the flagella is locomotion. On the other hand, shorten cilia often has the function in sensing the extracellular environment.</span>
Answer:
Rain
Explanation: Rain can wet the mud, and cause it to slide. This is one cause of a landslide that humans don't cause. This is why rain is a natural cause for lanslides.
Answer:
they are controlled by means of three basic techniques: absorption, adsorption, and incineration (or combustion). These techniques can be employed singly or in combination.
I would have to say the first option.
Due to the fact that Africa and South America do not have similar coasts, fossils prove that used to be the continent of Pangaea, and location of the plates had boundaries, but they were not affected by Earth's magnetic fields.
