13. Scientist have been collecting data for a number of years on the number of elephants in one of Africa's largest national parks. Based on the data below, in which year is it most reasonable to conclude that
the pork experienced a severe drought, when very little rain fell and the animals did not have enough water?

Rank the three variables in terms of how strongly they affect the "species" composition of the bacterial communities. place the variable with the weakest effect on the left and the variable with the strongest effect on the right.

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.

Looking at this image, what relationship can be drawn from it? the lower the degree of latitude, the lower the degree of temperature there is no relationship between latitude and temperature the higher the degree of latitude, the higher the degree of temperature the lower the degree of latitude, the higher the degree of temperature
