The first option
Explanation:
Groundwater flows faster where the hydraulic gradient and/or hydraulic conductivity are larger. Groundwater flow velocities are much slower than surface water flow velocities, except in limestone karst formations, where groundwater flows through caves and large solution channels.
Answer:
Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.
Salt water is a hypertonic solution in comparison to the internal cellular liquid, since there are more solute particles outside in the salt water than inside in the cytoplasm. This means that water will move out of the cells by osmosis due to the concentration gradient, and the cells will become shrivelled. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
