What are the 4 biotic factors in an ecosystem? Biotic and abiotic factors Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals. What is the role of producers in most ecosystems? As producers are the first level in a food system, they […]

When something is in motion it is changing?
When something is in motion it is changing? Something is in motion if it is changing position. It could be a fast-moving airplane, a leaf swirling in the wind, or water trickling from a hose. Even your school, attached to Earth, is moving through space. When an object moves from one location to another, it […]
How do you find the refractive index of oil?
How do you find the refractive index of oil? The refractive index of essential oils can easily be measured with an Abbemat refractometer. It can thus provide insight as to their quality. Does oil have the same refractive index as glass? You see a glass object because it both reflects and refracts light. When light […]
Why digital signals are better than analog?
Why digital signals are better than analog? The configuring process of digital signals is easier than analog signals. Digital signals can be saved and retrieved more conveniently than analog signals. Many of the digital circuits have almost common encoding techniques and hence similar devices can be used for a number of purposes. Is the human […]
How do bacteria multiply?
How do bacteria multiply? Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell. What […]

Explanation: Wind is free and renewable form of energy, which throughout history has been used to grind grain, power ships, and pump water. Wind is created when the sun unevenly heat the earth […]
Where is pair production used?
Where is pair production used? Pair production also can occur in the field of an atomic electron, to which considerable recoil energy is thereby imparted. The threshold for such a process is four times the rest energy of an electron, or 4mc2. The total pair-production cross section is the sum of the two components, nuclear […]
What are 3 examples of the evidence of energy?
What are 3 examples of the evidence of energy? Heat, sound, light and motion are evidence of energy in a system. Students will be able to reflect on what they have learned and review key vocabulary. They will consider ways they use energy each day and identify systems or behaviors they could change in order […]
Which element is alone in its own family?
Which element is alone in its own family? Hydrogen What is a family of elements called? The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. Which two […]
