Which protein is insoluble in water? Explanation: In a globular protein, the amino acid chain can twist in a way that polar groups lie at the protein’s surface. This allows the protein to interact with water and enhances the protein’s solubility in water. This does not occur in fibrous proteins, so fibrous proteins are insoluble […]

What happens to potential energy when melting? When ice or any other solid melts, its potential energy increases. Since the thermal kinetic energy, or temperature, does not increase while melting…. What does Bose Einstein condensate do? Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero […]

How does tissue fluid return to the blood? The water in the tissue fluid moves back into the capillary by osmosis due to a water potential gradient between the tissue fluid and the blood. Any remaining tissue fluid is called lymph which is drained into the lymphatic system and is eventually returned to the blood. […]

What will happen to the Great Rift Valley in Africa eventually? Eventually, it will rupture, leading to the formation of a rift valley. This process is accompanied by surface manifestations along the rift valley in the form of volcanism and seismic activity. Rifts are the initial stage of a continental break-up and, if successful, can […]

What are the correct steps to find the range of a data set? Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find it, first order the data from least to greatest. Then subtract the smallest value from the largest value in the […]

What is the first law of life? The first law is often referred to as the Law of Inertia. The law states that every object will remain at rest or continue in a straight line unless compelled to change its state by the action of an external force. In other words, things stay the way […]

Is bread sold by weight? No – it is the weight of the finished loaf that counts – but it is a good idea to do so in order to ensure that the weight of finished loaves is consistent. It is recommended that the weight for dough pieces for each type of bread be displayed […]

What two factors affect pressure? Area and force are the two factors on which pressure depend. What happens to the volume when the pressure doubles? For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure. That means that, for example, if you double the pressure, you will halve […]

Which is an example of abiotic factor? An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem. […]
