Which form of succession replaces<br> an<br> existing system after a calamity?

lina2011 [118]

Answer:

Secondary succession

Explanation:

Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.

Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.

Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.

Phoenix [80]

Answer:

seafloor

Explanation:

A plate, often described as a lithospheric plate, with seafloor, continents and mountains on top of it.
The earth is divided into three layers based on their chemical composition. Undoubtedly, there is a component called the lithosphere.
The lithosphere consists of a crust and a portion of a solid upper mantle.
Below the lithosphere is the asthenosphere.
There are two types of crusts: the continental crust and the oceanic crust.
Where there is a seabed there is a sea crust.
Mountains are also found in oceanic and continental crusts.
The intercontinental layer corresponds to the continents.

Pyruvate dehydrogenase is regulated by feedback inhibition and covalent modification. Which molecules inhibit the pyruvate dehyd

Oksi-84 [34.3K]

ADP, NAD+, CoA-SH, and pyruvate are the molecules that inhibit the pyruvate dehydrogenase complex.

<h3>What is pyruvate dehydrogenase complex?</h3>

PDC3 triggers the oxidative decarboxylation of pyruvate, resulting in the creation of acetyl-CoA, CO2, and NADH.

The PDC plays a crucial role in the oxidation of glucose by connecting the glycolytic pathway to the tricarboxylic acid cycle's oxidative pathway.

ADP, NAD+, CoA-SH, and pyruvate all inhibit it. PDK prevents glycolysis from being coupled to GO by inhibiting its target enzyme PDH.

Thus, the answer is ADP, NAD+, CoA-SH, and pyruvate .
