The oxygen level of a lake suddenly starts decreasing. a biologist believes that photosynthetic organisms in the community have become less efficient at producing oxygen. a geologist believes that changes in the ground have increased the inflow of water into the lake. why are both of these options valid scientific hypotheses?
scientists with different educational backgrounds can come to different interpretations of the same data.
both scientists have graphs and charts to support their hypothesis.
both are valid because they are supported by experimental data
both scientists underwent the same training and, therefore, have equally valid scientific hypotheses regardless of the available data.

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.

Ascientist separates a population of mice into two groups. what would most likely increase the rate of speciation in this population. a. teach the two groups different tricks b. allow the two groups to breed with each other c. put the two groups in different environment d. have the two groups live in identical ecosystems

To be or not to be that is da question
