<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
Answer:
humans use their knowledge to locate resources.
Explanation:
The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.
The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.

Answer:
D. magnetism, electrical conductivity, high melting point
Explanation:
Magnetism is the property of metal due to which they are attracted by magnets. Metals have high electrical conductivity which means they are good conductors of electricity. They also have high melting points i. e. they require high amount of heat to change its solid state into liquid state. In melting, bonds are broken down due to the applicable of heat energy.
Freud is to free association, while on the other hand, Rogers is to active listening. These are great people who modeled the foundation of psychology as what we understood right now. Sigmund Freud is the founder of psychoanalysis while Rogers is the founder of the humanistic approach to psychology.
It's a mutualism relationship because both species can benefit from each other.
