Answer:
When you stand in sunlight, you feel warmer than when you are in shadow, so you can feel that light from the sun carries energy that can warm an object—you. You can feel the warming effect, even if the sunlight comes through a window before it hits you. In the same way, the soil, pots, plants, and so on inside a greenhouse, like the one pictured here, are warmed by the sunlight that shines through its transparent walls and roof. The air inside the greenhouse is then warmed by contact with the warm objects. If the door and ventilation windows are closed, the warm air can’t escape, so the temperature of everything in the greenhouse goes up.
Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
The correct answer is generosity, fairness.
Values refer to an individual's idea of what is right and ethical in life. Values also set standards for an individual's behavior and conduct. Generosity refers to a value where a person believes in sharing, giving and extending oneself to help others. The value of fairness refers to when a person believes in equality, justice and parity for everyone.
In order to assimilate, a minority group could:
(C.) Adopt the dress of the dominant group
Assimilation is the process of adopting (often by a minority group) the ideas of another’s culture/way of life (often a majority group).
