Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.
Answer:
Competition.
Explanation:
The interaction between the organisms can be beneficial harmful or neutral depending on the types of organisms. Different types of interaction are mutualism, ammensalism and commensalism.
The competition occurs when the individual compete for the same resources or for the habitat. The competition results in the exclusion of one species and determines the distribution of other species.
Thus, the answer is competition.
<span>The answer is I, II and III. These
microbes can be funds even in hydrothermal vents at the bottom of ocean
trenches where they convert chemicals to organic matter. Most are critical in
the many nutrient cycles such as the nitrogen and carbon cycles. These microbes form the
base of the food chain since they support higher organisms such as paramecium
which are in turn eaten by higher organism such as amoeba. The amoebas are then
fed by tadpoles, for example, and the tadpoles are eaten by fish…and etcetera. </span>
