As you can see in the table presented below, in the first few years after the eruption, there was a significant number of moss species present.
Pioneer species are species that are very resilient and first to inhabit new habitats or repopulate disrupted ones, so in this example, mosses are the most likely candidate for pioneer species.
The experiment must maintain internal and external validity, or the results will be useless. When designing an experiment, a researcher must follow all of the steps of the scientific method, from making sure that the hypothesis is valid and testable, to using controls and statistical tests
Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle
Explanation:
By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.
This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.
In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.

Answer:
Speciation
Explanation:
Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics
Because they may just never know they can't know every case that has happened lol
