Seasons are Winter, Spring, Summer And Fall. The Sun moving (orbiting earth) causes them. So in the winter, the sun is on the opposite side of the world, and that's why it is so cold. In the summer, the sun is facing straight at us. Other season's, the sun is kinda in between, if that is any help

Answer:
Decrease population of staghorn coral and spotlight parrot fish.
Explanation:
Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.
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.
