What two things do plants need to grow?
What two things do plants need to grow? Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN). […]
How many Hertz can kill you?
How many Hertz can kill you? 7 hz Can a sonic boom kill you? Can a sonic boom kill you ? High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage. The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart […]
What is the average kinetic energy of water molecules is greatest in?
What is the average kinetic energy of water molecules is greatest in? 273 K What is the average kinetic energy of a water molecule? The energy required to break the water loose (~40 kJ/mol, according to Poutnik’s answer) is much higher than the median collision energy at room temperature (~2 kJ/mol). Whether the water molecule […]
What is the primary level of protein structure?
What is the primary level of protein structure? The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain. What are the disadvantages of protein? Risks of eating too much protein Weight gain. High-protein diets may tout weight loss, but this type of weight loss may only […]
What type of scale is the Kelvin scale?
What type of scale is the Kelvin scale? Kelvin temperature scale, a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero, or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of −273.15° on the Celsius temperature scale. Why does the Kelvin […]
What is the criteria for spontaneity in terms of free energy change?
What is the criteria for spontaneity in terms of free energy change? Criteria for spontaneity in terms of free energy change: (i) If ∆G is negative, the process is spontaneous. (ii) If ∆G is positive, the direct process is non-spontaneous. (iii) If ∆G is zero, the process is in equilibrium. What does spontaneity mean? 1 […]
What kind of market structure is an oligopoly quizlet?
What kind of market structure is an oligopoly quizlet? Oligopoly is a market structure dominated by only a few large profitable firms. In economics, it usually uses the four-firm market ratio (at least four firms control more than 40% of the market). A series of competitive price cuts that lowers the market price below the […]
What is a group of organisms and their environment?
What is a group of organisms and their environment? Populations are made up of all the members of a species living in the same place at the same time. A community includes all the populations of the area. The community and the abiotic factors make up the ecosystem. An organism lives in its habitat within […]
