What happens when a cell with 1% salt gets put into a 10% salt solution? It is a type of passive transport. A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration. Water will move out of the cell, causing it to shrink. What are examples of […]

How do you do a well yield test? Determine the volume in gallons per foot of well bore based on the well diameter (Table 1). Multiply the gallons per foot of well bore times the footage of water level rebound during the recovery. Then divide the result by the time of this recovery to a […]

Why elastic force is called conservative force explain? A conservative force is a force done in moving a particle from one point to another, such that the force is independent of the path taken by the particle. It depends only on the initial and final position of the particle. Gravitational force and elastic spring forces […]

What are the causes of convection current? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Where can convection currents […]

Why is evaporation important how can it help you? The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. Once water evaporates, it also helps form […]

How much energy is used in photosynthesis? The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein. What percentage of sunlight is used in photosynthesis? 3 percent What organisms use energy for […]

What is a chain reaction simple definition? 1a : a series of events so related to each other that each one initiates the next. b : a number of events triggered by the same initial event. 2 : a self-sustaining chemical or nuclear reaction yielding energy or products that cause further reactions of the same […]

Which forest layer has the greatest amount of net primary productivity? Basic ideas – NPP in terrestrial ecosystems Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate. Which biomes are most affected by humans? Tropical dry forests and temperate […]

Could we survive on earth without the greenhouse effect quizlet? What is the greenhouse effect? No we would not be able to survive because without these gases, the Earth would be too cold for humans, plants and other creatures to live. The two largest greenhouse gases are Co2 and methane which comes from fossil fuels […]

What is the most popular personal retirement plan? IRAs. The IRA is one of the most common retirement plans. An individual can set up an IRA at a financial institution, such as a bank or brokerage firm, to hold investments — stocks, mutual funds, bonds and cash — earmarked for retirement. What happens to your […]
