What is the function of the sodium potassium pump in nerve cells? It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium ions out for every 2 potassium ions brought in. In the process, the pump helps to stabilize membrane potential, and thus is essential in creating […]
Why do compasses not point south?
Why do compasses not point south? A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth’s magnetic poles, which are not the same as earth’s geographic poles. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, […]
Is there a place with no natural disasters?
Is there a place with no natural disasters? Bahrain. Bahrain is often ranked as one of the safest places due to the low frequency of natural disasters and government security. It is a small monarchy in the Persian Gulf. Other than dust storms and hot summer, there is not much danger from extreme natural disasters. […]
Is the crust the least dense layer?
Does plant take in oxygen at night?
Does plant take in oxygen at night? Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration. How do plants know night? A plant’s “eyes,” or light-sensitive proteins, signal whether it is day […]
What are the 4 products of photosynthesis?
What are the 4 products of photosynthesis? The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water. Photosynthesis Reactants. Products of Photosynthesis. Light-Dependent Process. Light-Independent Process. The Overall Process. What are two major products of photosynthesis? Specifically, plants use energy from sunlight to react […]
Did the electron move into a region of higher potential or lower potential?
Did the electron move into a region of higher potential or lower potential? Because the electron is a negative charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. Because the electron is a positive charge and it accelerates as it […]
Which molecules have a dipole moment?
Which molecules have a dipole moment? Molecular Dipole Moment carbon dioxide: 0 (despite having two polar C=O. carbon monoxide: 0.112 D. ozone: 0.53 D. phosgene: 1.17 D. water vapor: 1.85 D. hydrogen cyanide: 2.98 D. cyanamide: 4.27 D. potassium bromide: 10.41 D. Which molecule does not have a dipole moment? Each C–O bond in CO […]
What is the first step in the pathway of a nerve impulse?
What are the two most common types of reservoir rocks?
What are the two most common types of reservoir rocks? Reservoir rocks around the world is dominated by sedimentary rocks because generally it has primary porosity. Igneous and metamorphic rocks can be reservoir if there are in fracturing state (secondary porosity). What is the most abundant carbonate rock? limestone How can you tell if a […]
