It means there are more negatively charged particles on the inside of the membrane than on the outside. Hope this helps.
Student A who believes viruses are non living organisms.
Explanation- Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy.
Answer;
A. shape, elevation, and steepness of features
Explanation;
-A topographic map is a detailed and accurate two-dimensional representation of natural and human-made features on the Earth's surface. These maps are used for a number of applications, from camping, hunting, fishing, and hiking to urban planning, resource management, and surveying.
-These map show the three-dimensional shape of the land. Most topographic maps make use of contour lines to depict elevations above sea level. The contour lines reveal the shape of the land in the vertical direction, allowing the 3-dimensional shape of the land to be portrayed on a 2-dimensional map. Contour lines are drawn on a topographic map to show the location of hills, mountains and valleys.
Solution: The rapid rise and fall in the membrane potential across a cell's membrane is known as action potential. The generation of the action potential is necessary for the transfer of the nerve impulses across the neurons. The nerve impulses are generated only when the cell membrane is depolarized to its threshold level. These potentials are generate din response to different stimuli. When this stimulus is long, the recovery time is increased and the action potentials are allowed to occur after the relative refractory period above the threshold. (A refractory period can be defined as the time during which no action potential can be generated.)
This causes the generation of the multiple action potentials.
Carbon and hydrogen is the most abundant elements, respectively, in proteins.
