How do gray whales collect and eat such small organisms? They use their countershading to sneak up on their prey items. They emit high-pitched sounds that drive their prey items into tight masses. They use cooperative behavior to corral them into a group and then swallow their prey items whole. They use a technique called bubble-net feeding. They use their baleen to filter prey items from their environment.

Why are researchers exploring the use of the radish as a cover crop? Global consumption of radishes has increased dramatically in recent years. It may be able to conserve most fall-applied nitrogen on the same fields where it is applied, thus preventing nutrient runoff. Radishes are increasingly being used as a biofuel. Radishes can eliminate the need for fertilizers during the spring and fall. Radishes are ground up and used as fertilizer.

What is causing a decline in Antarctica's Chinstrap penguins? An increase in the leopard seal population, who feed on the penguins, Has impacted the penguin population. Warmer temperatures have allowed diseases to spread through the Chinstrap population. Unregulated hunting in the waters off Antarctica has decimated the population of these penguins. Populations of the penguin's major food source are declining because of melting sea ice. The Chinstrap penguins are not able to migrate back to breeding grounds in Antarctica by way of sea ice because the ice is disappearing.

Which of the following best describes the role of biological activity in soil development? Earthworms increase soil porosity and contribute to soil movement and organic content. Broadleaf trees tend to increase the alkalinity of soil, whereas needleleaf trees increase the acidity. Plant roots provide channels for air and water movement in soils. All organisms living in, on, and over the soil, influence soil development and characteristics: they can influence the pH, the organic matter, chemical content, and biological content of soils.
  • Earthquakes with magnitude greater than 4.0 occur in a pattern than correlates closely with plate boundaries.

If the northern slopes had been less steep initially (same height), the eruption would likely have happened later. If the northern slopes had been steeper initially (same height), the eruption would likely have happened later.
