What are questioning techniques? Questioning techniques – a set of methods used by teachers when asking questions, such as wait time and bounce. Experienced teachers recognise the power of questions. When skilfully delivered, questions boost student engagement, improve understanding and promote critical thinking. What are the components of questioning? The components of a question Subject […]
What happens if an atom is destroyed?
What happens if an atom is destroyed? Destroying matter and destroying an atom are two different things. As the basic laws of conservation of mass and energy goes. Matter cannot be created, nor be destroyed but it changes its form from matter to energy. In the destruction of an atom (fission), the components of an […]
How many moles of Al2O3 are formed when .78 mol O2 reacts with aluminum?
How many types of proteins are there?
How many types of proteins are there? Protein is the basic component of living cells and is made of carbon, hydrogen, oxygen, nitrogen and one or more chains of amino acids. The three types of proteins are fibrous, globular, and membrane. How many proteins are there in humans? 400,000 proteins How many proteins are in […]
How do RBC survive without nucleus?
How do RBC survive without nucleus? The red blood cells without nuclei, called reticulocytes, subsequently lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum. The spleen acts as a reservoir of red blood cells, but this effect is somewhat limited in humans. Is RBC a living cell? rbcs are living […]
How is energy transferred in a bicycle?
How is energy transferred in a bicycle? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that […]
Why do electrons lose or gain electrons?
Why do electrons lose or gain electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms). […]
What is max current?
What is max current? Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Also described as current-carrying capacity. Electric current flowing through them causes voltage drop and power dissipation, which heats conductors. How do you find the maximum and […]
What does the body use first for energy?
What does the body use first for energy? Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy […]
