Answer:

The correct answer is - B. Lichens.

Explanation:

Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.

Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.

What is the difference in the beginning between primary succession amd secondary succession
lianna [129]
Primary succession is when, for example, a volcano explodes and there is nothing left and even the soil is ruined. It would take at least a hundred years for the land to be like it was before the volcano erupted. Secondary succession is when, for example, a wild fire happens but the soil is not ruined. It would take at least 25-50 years for the land to be like it was before the fire.

Which of the following is not a cellular activity associated with microtubules?
sladkih [1.3K]

Answer:

A. maintenance of axons is not a cellular activity associated with microtubules.

Explanation:

Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
