Answer:
The membrane potential is maintained in the cell due to the unequal distribution of the ions inside and outside of the cell. This membrane potential is important for the conduction of the nerve impulse.
The arrival of the stimulus triggers the action potential. The resting membrane potential is -70mV. This is maintained by the presence of potassium ions. The influx of the sodium ions result in the change in the membrane potential from -70mV to +30mV.
It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
The answer is true. When two tectonic plates are sliding past each other, it results in shear stress, and shear stress leads to an earthquake.
Answer:
Biosphere
Explanation:
The biosphere contributes to life. The biosphere is important for the survival of our own lives, and it also it is the zone of the earth where the air, land, water, and other abiotic elements interact together to support our whole lives.
Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. Therefore, this is the layer that farmers want to protect for growing their crops and ranchers want to protect for growing grasses for their cattle to graze on.
