Why does a tree cry? Do trees cry? Yes, when trees are starved of water, they certainly suffer and make a noise. In drought-stricken trees, this increased pressure can cause the water column to break, allowing dissolved air to form bubbles that block water flow. What to do if tree is leaking sap? The best […]
Can you add voltages in parallel?
Can you add voltages in parallel? Ideal voltage sources can be connected together in both parallel or series the same as for any circuit element. Series voltages add together while parallel voltages have the same value. Note that unequal ideal voltage sources cannot be connected directly together in parallel. What happens when two different batteries […]

What are the impacts of desertification?
What are the impacts of desertification? What are the effects of desertification? Lack of vegetation cover for holding soil together and for grazing. Increased soil erosion. Crop failure, leading to famine . What are the major causes of desertification? ‘Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification. removal […]
How do genes and environment affect behavior?
How do genes and environment affect behavior? Genes, via their influences on morphology and physiology, create a framework within which the environment acts to shape the behavior of an individual animal. The environment can affect morphological and physiological development; in turn behavior develops as a result of that animal’s shape and internal workings. How can […]
What are the 2 types of Heterotrophs?
What are the 2 types of Heterotrophs? There are two subcategories of heterotrophs: photoheterotrophs and chemoheterotrophs. Photoheterotrophs are organisms that get their energy from light, but must still consume carbon from other organisms, as they cannot utilize carbon dioxide from the air. What are 4 types of Heterotrophs? There are four different types of heterotrophs […]
Does temperature affect pitch?
Does temperature affect pitch? In other words temperature does affect the pitch. Higher temperature will cause the air molecules that come in contact with your instrument to have a higher average speed. This would give the sounds played a higher pitch. A slower average speed, as in a cold room, would cause a lower pitch […]
What are the 4 evidence of continental drift?
What are the 4 evidence of continental drift? The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. Why did Pangea break up? During the Triassic Period, the immense Pangea landmass began breaking apart as a result of […]
What is population ecology example?
What is population ecology example? Population ecology is the study of how these populations interact with the environment. The effects that density-dependent factors may have on a population are determined by its size; for example, a larger, denser population will be decimated more quickly by the spread of disease than a widely dispersed population. How […]
How do humans benefit from the water cycle?
How do humans benefit from the water cycle? The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life. How can we […]
