What causes acceleration? Acceleration and velocity Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the […]

How is temperature affected by sunlight? Sunlight Changes With The Seasons When rays of sunlight hit the earth, the earth itself warms up. This, in turn, warms the atmosphere. This is the actual temperature we feel and measure with a thermometer. The temperature of the earth’s atmosphere is also determined by the angle at which […]

What instruments are used to predict volcanic eruptions? Volcanologists’ Tools Tiltmeters. Scientists use tiltmeters to measure extremely subtle changes in a volcano’s slope. Gas Samples. A geologist cools a sample of molten lava in a can of water. Thermal Imagers. Seismic Monitors. Radar Mapping Instruments. What clues can scientists look for to predict a volcanic […]

Consider dropping daytime breastfeeds first, then gradually drop any bedtime or night-time feeds – these are probably the ones that give your child the most comfort. […]

How is mass spectrometry used for protein analysis? Mass spectrometry (MS) analysis of proteins measures the mass-to-charge ratio of ions to identify and quantify molecules in simple and complex mixtures. How do you Analyse Protein-Protein Interaction? The in vitro methods in PPI detection are tandem affinity purification, affinity chromatography, coimmunoprecipitation, protein arrays, protein fragment complementation, […]

What is assimilation and accommodation example? When the child encounters a horse, they might assimilate this information and immediately call the animal a dog. The process of accommodation then allows the child to adapt the existing schema to incorporate the knowledge that some four-legged animals are horses. What is the definition for assimilation? Assimilation, in […]

What is associative long term potentiation? Definition. Long-lasting increase in the efficacy of synaptic transmission, induced in an input that is active when LTP-inducing high-frequency stimulation is applied to another independent strong input. This type of LTP is called “associative LTP.” What occurs during long term potentiation? In neuroscience, long-term potentiation (LTP) is a persistent […]

What are the 3 parts of collision theory? There are three important parts to collision theory, that reacting substances must collide, that they must collide with enough energy and that they must collide with the correct orientation. What are the conditions for collision theory? The collision energy must be greater than the activation energy for […]
