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.

Answer:
The answer is Carbohydrates.
Explanation:
<u>They are one of the most important nutrient.</u>

Cyanobacteria helped produce O2. Because it helped releasing O2 into the atmosphere, today we see different animals because Cyanobacteria helped reduce the poor oxygen in the atmosphere.
Answer:
Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.
Explanation:
Since the four proteins used p16, p18, p21, and p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.
Hope that answers the question, have a great day!
