C i’m pretty sure. correct me if i’m wrong :)
The distance should be 11 cm and the image will be inverted (and smaller)
I used the Lens Equation:

Where:
obj. is the distance of the object
im. is the distance of the image
f is the focal length
In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food; food that we use, too, when we eat plants or animals that have eaten plants and they release the oxygen into the atmosphere.
So it’s PHOTOSYNTHESIS
The answer to number 9 is C, decreased muscle tension. I believe number 10 is D, prepares an organism to respond to stress.
The wavelength of the given wave is calculated through the equation,
λ = c/v
where λ is the wavelength,
c is the speed of light, equal to 3x10⁸ m/s, and
v is the frequency
Then, we substitute the known values to the equation,
λ = (3 x 10⁸ m/s)/(1280 x 10³/s)
λ = 234.375 m
The wavelength of the "am" radio station is 234.38 m.
