Answer:
The earliest oxygen-producing life forms were Cyanobacteria. Besides Cyanobacteria, these tiny organisms have another name known as blue-green algae
Explanation:Some scientists think that 2.4 billion years ago is when organisms called cyanobacteria first evolved, which could perform oxygen-producing (oxygenic) photosynthesis. Other scientist think that cyanobacteria evolved long before 2.4 billion years ago but something prevented oxygen from accumulating in the air

Answer:
Option A, Central Ohio
Explanation:
Deciduous trees are prominent in Louisiana, Ohio, California and Florida landscapes and include mainly oak trees magnolia trees, bald cypress, sugar maple, hollies, vitex etc.
These tropical deciduous trees lose their leaves to conserve water during dry weather season and then regrow during suitable growing season.
Temperate deciduous trees shed their leaves during cold weather and tropical deciduous trees shed their leaves during dry season.
In Central Ohio, temperature is lower than 0 degree Celsius and hence deciduous trees will loose their leaves during winter.
Hence, Option A is correct
Changing usage from non environmentally safe products to green tech will help bring down global warming and greenhouse gasses. If we were to use green tech we could save the world from dying of global warming and acid rain. Using non fuel-efficient cars and using factories causes environmental damage, destroying the planet.
Hope it helps! (:
