Which are typical pioneer species during primary succession?

Biology
1 answer:
JulijaS [17]4 years ago
3 0

Answer & explanation:

Primary succession occurs in environments that did not have biological communities in place and present unfavorable conditions for the establishment of life. Examples of these sites are rocks, dunes and newly solidified lava pits.

The pioneer organisms in primary succession are mainly producers and some decomposers.

In <u>dune</u> <u>environments</u>, for example, there are grasses, whose seeds are wind-borne and able to withstand excessive heat, water scarcity and unstable soil, and their roots are firm, preventing these plants from being harmed by the wind.

Sites with <u>rocky</u> <u>surfaces</u> can be colonized by photosynthetic bacteria, fungi or some species of algae. These organisms release substances that alter the substrate, allowing the installation of new species over time.

BaLLatris [955]

Answer:

Protein kinase C.

Explanation:

Protein kinase C may be defined as the enzymes that controls the function of proteins by phosphorylation of the specific substrate. This enzyme mainly phosphorylate at the hydroxyl group at Serine and Threonine amino acids.

The protein kinase C enzyme acts on the substrate phosphatidylinositol 4,5-bisphosphate (PIP 2). This result in the formation of secondary messenger like phosphatidylinositol 3,4,5-trisphosphate (PIP 3) and diacyglycerol (DAG). They shoe the similar transduction pathway as shown by phospholipase C.

Thus, the correct answer is option (D).
