What happens to yeast in warm water? When the warm water hits the yeast, it reactivates it and “wakes it up.” Then it begins to eat and multiply. The yeast organism feeds on the simple sugars found in flour. As they feed, they release chemicals and gases like carbon dioxide and ethanol, along with energy […]
What is one oscillation of a simple pendulum?
What is one oscillation of a simple pendulum? One oscillation of a simple pendulum is one complete cycle of swinging one way and then returning to its original starting position. How do you find the frequency of oscillation of a pendulum? How to analyze a pendulum in swing Determine the length of the pendulum. Decide […]
What would have resulted from the functions of prokaryotes on early Earth?
What would have resulted from the functions of prokaryotes on early Earth? The most appropriate answer would be option D. The first life appeared on earth was probably the prokaryotes. Some of them called cyanobacteria discovered the process of harnessing energy from the sun, that is, photosynthesis. The oxygen was released as the byproduct of […]
Is Fusion a chain reaction?
Is Fusion a chain reaction? Can fusion cause a nuclear accident? No, because fusion energy production is not based on a chain reaction, as is fission. What is chain reaction with example? In chain reaction. Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a […]
In which situation is a person doing work on an object?
In which situation is a person doing work on an object? Answer : When a person applies force and covers distance then the person is doing work on an object. What type of force causes a change in motion? Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the […]
What are two ways to calculate gravitational potential energy?
What are two ways to calculate gravitational potential energy? Gravitational potential energy changes into kinetic energy. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters. How do […]
Why do the dark-colored mice living on lava flows have white underbellies?
Why do the dark-colored mice living on lava flows have white underbellies? The mice’s underbellies are white because there’s so selective pressure for it to be dark; the predators come from above. The differences in mouse fur color are driven by natural selection. Why do the pocket mice in the dark lava environment have white […]
What is an example of deductive reasoning?
What is an example of deductive reasoning? For example, “All men are mortal. Harold is a man. Therefore, Harold is mortal.” For deductive reasoning to be sound, the hypothesis must be correct. It is assumed that the premises, “All men are mortal” and “Harold is a man” are true. What is induction method of teaching? […]
Why there is fall in temperature with altitude?
Why there is fall in temperature with altitude? As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with […]
