Explanation:
I just took the quiz on Apex :)
The fovea centralis is tightly packed with receptors which can receive clear and highly detailed information.
The fovea centralis, or fovea, is a small depression within the neurosensory retina where visual acuity is the highest.
The fovea itself is the central portion of the macula, which is responsible for central vision.
To form high resolution images, the light must fall on the fovea, and that limits the acute vision angle to about 15 degrees.
In low light, this fovea constitutes a second blind spot since it is exclusively cones which have low light sensitivity.
Human fovea consists of 3 spectral types of cones: long wavelength cones, medium wavelength cones and short wavelength cones.

its B...
because a composite cell has a cell wall, vacuole, and cell membrane but doesnt include any of the plant cells so i know its B
Mass number = total protons + neutrons, and proton number = total protons (and therefore electrons, if not an ion.) Therefore: Neutrons = 12 - 5 = 7 Protons = 5 Electrons = 5
Answer:
the answer is the second option.
