Which region lies between the desert and the savanna in Africa? The Sahel is a narrow band of semi-arid land that forms a transition zone between the Sahara to the north and the savannas to the south.

Is heating curve exothermic?
Is heating curve exothermic? On any heating curve, energy is added and therefore it is always endothermic. On any cooling curve, energy is released and therefore it is always exothermic. Why is freezing exothermic? When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction. Usually, this heat […]
What causes umbra and penumbra?
What causes umbra and penumbra? An “umbra” is the part of the shadow where all of the light from the source is blocked by the shadowing object. A “penumbra” is that region around the umbra where the shadow is only partial, or imperfect. You get these when the light source is larger than a single […]
How can we get people to change behavior when it comes to climate change?
How can we get people to change behavior when it comes to climate change? A better approach to inspiring people to change their behavior is education. Education on the benefits of change empowers people to make decisions that they feel are in their best interest rather than being forced into it by others. The Mainstreaming […]
Can we make energy from mass?
Can we make energy from mass? Specifically, small amounts of mass are turned into energy from the breaking up (fission) or combination (fusion) of the nuclei of atoms. Even spontaneous radioactive decay converts a bit of mass into incredible amounts of energy. Can you create mass from light? Breit and Wheeler suggested that it should […]
Where are feature detectors?
Where are feature detectors? Perception is created in part through the simultaneous action of thousands of feature detector neurons—specialized neurons, located in the visual cortex, that respond to the strength, angles, shapes, edges, and movements of a visual stimulus (Kelsey, 1997; Livingstone & Hubel, 1988). Are complex cells in V1 feature detectors? Complex cells can […]
What are two examples of mechanical digestion that occurs to break down food?
What are two examples of mechanical digestion that occurs to break down food? Churning (Stomach) The stomach lining contains muscles which physically squeeze and mix the food with strong digestive juices (‘churning’) Food is digested within the stomach for several hours and is turned into a creamy paste called chyme. What are the three examples […]
