Many farmers and gardeners compost their plant and animal waste. the living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. the next season, farmers use this substance as a natural fertilizer for their crops. a biology student has grown tomato plants for several years. until now, he used an artificial fertilizer formulated for tomato plants. this fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. the student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. answer the following questions to plan an investigation using the steps of the scientific method and the student find the answer to his question. part f how does the design of your experiment control for outside factors that may affect the results

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
