Scientists conducted an experiment to determine how different wavelengths of light affected photosynthesis. they used two groups of the same plants. the leaves of group 1 were covered with transparent green plastic. the results show that the pants photosynthesized best when their leaves were not covered in any plastic. which hypothesis do the results support?
a. if leaves are uncovered, then their chloroplasts will produce more oxygen than the leaves that are covered in green plastic.
b. if leaves are covered in green plastic, then their mitochondria will absorb more carbon dioxide than the mitochondria of uncovered leaves.
c. if leaves are uncovered, then their chloroplasts will release more carbon dioxide than the chloroplasts of leaves covered in green plastic.
d. if leaves are covered in green plastic, then their mitochondria will produce more oxygen than the leaves that are uncovered.

Suppose a scientist measures the amount of dna per cell of a particular diploid species at various stages of meiosis. she finds that the meiotic cells contain 3.7 pg , 7.3 pg , or 14.6 pg of dna. match each stage of the cell cycle to the corresponding amount of dna contained within a cell at that stage.

Pixels are often referred to using dpi, or dots per inch. true\false

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.
