Answer:

d.Primary Succession

Explanation:

ECOLOGICAL SUCCESSION is the series of changes that a particular ecosystem undergoes over a particular period of time. Ecological succession can be of two types viz: primary succession and secondary succession.

Primary succession is a type of ecological succession that involves the colonization of a barren area of land with no soil i.e. no pre-existing organisms. The barren area consists of bare rocks and surfaces that are colonized by organisms like LICHENS for the first time. These organisms are called PIONEER.

The lichens act on the bare rocks by secreting chemicals that help degrade the rock particles to form soil, which paves way for other organisms like plants to grow.

What is the role of pH in the maintenance of DNA inside a nucleus? How can pH be disrupted?
inysia [295]

Answer:

heyooooo!!!!!!

Hydrogen ions play a central role in the lives of cells. For example, changes in hydrogen ion concentration are intimately tied to the charge of side chains in proteins. This charge state, in turn, affects the activity of enzymes as well as their folding and even localization. Further, the famed ATP synthases that churn out the ATPs that power many cellular processes are driven by gradients in hydrogen ions across membranes.

hope this helps!!

What would be the best explanation for why myelinated fibers conduct signals faster than unmyelinated fibers?
Sliva [168]

Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,

Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.

The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.

Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.

In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.

The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along  these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions  diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.

Unmyeinated lacks myelin sheath,therefore the exchange and  the rate of diffusion of ions along the axons is low.
