How do I identify an alluvial fan?
How do I identify an alluvial fan? Check the mouths of tributaries in larger valleys while in the field. Check topographic maps, and look for fan shaped elevation lines at the mouths of tributaries. Check soils maps for soils designated as “local alluvium.” What is the human impact of alluvial fan? Willful and continuous interference […]
What does a horizontal line indicate?
What does a horizontal line indicate? A horizontal line is commonly used in technical analysis to mark areas of support or resistance. A horizontal line runs parallel to the x-axis.

Is chromatin made of nucleosomes?
Is chromatin made of nucleosomes? Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones.

Which gases is not a greenhouse gas?
Which gases is not a greenhouse gas? Examples for greenhouse gases: Carbon dioxides, Methane, Chlorofluorocarbon, sulphur dioxide. Whereas oxygen, nitrogen and argon are not examples of greenhouse gases. Is nitrogen monoxide a greenhouse gas? The direct greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The indirect greenhouse gases are non-methane volatile […]
Why capacitors are of little use for storage of energy?
Why capacitors are of little use for storage of energy? Capacitors are not ideal for energy storage because they discharge very fast and then they are of no use until recharged. Explanation: They are designed to perform different tasks than a battery. They are not suitable to deliver slow discharge for a long time like […]
What is a food chain in an ecosystem?
What is a food chain in an ecosystem? A food chain describes how energy and nutrients move through an ecosystem. In the food chain, energy is transferred from one living organism through another in the form of food.

What is the coating on the inside of a light bulb?
What is the coating on the inside of a light bulb? The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, […]
Why is Nhst bad?
Why is Nhst bad? NHST is unsuitable for large datasets Most NHST studies rely on nil null hypothesis testing (Nickerson, 2000) which means that H0 expects a true mean difference of exactly zero between conditions with some variation around this true zero mean. The p-value is smaller if the test statistic is larger. Why is […]
