Rods and cones are photoreceptors that are located in the retina of the eye. Rods are responsible for vision at low light levels while cones are responsible for vision at higher light levels. Therefore, rods are very sensitive to light. Rods work well at night when light is low. Cones, however, are responsible for color vision and high visual spatial acuity. Therefore, rods cannot distinguish colors. With these differences, the correct answer is:
A. Rods are very sensitive to light but do not distinguish colors.
Answer:
Duration of the magnetic polarity event
Rate at which the plates are moving away from the mid-ocean ridge
Explanation:
The marine magnetic anomaly usually refers to the variation that occurs in terms of the magnetic field strength of the earth. This takes place because of the presence of minerals within the rocks of seafloor that contains high magnetic property.
These magnetic anomalies occurring in the marine rocks cover only about 1% of the total strength of the geomagnetic field. It shows either positive or negative anomaly.
Some of the factors that influence the width of this marine magnetic anomalies on the rocks of ocean-floor includes:
- The amount of time it takes during the magnetic polarity event
- The rate at which the tectonic plates move at a divergent plate boundary from the mid-oceanic ridge.
Answer:
I'm sorry but you should do it on your own because if you don't you won't learn the way you should and plus that is cheating.
Basically, the disadvantages of a green roof are listed in the last sentence:
<span>"However, green roofs can be expensive to install, and require care and maintenance"
The disadvantage of a green roof would be there for the owners: the cost and time needed to have such a roof.
An additional disadvantage would be the possibility of the plants on the roof mixing with and replacing the local vegetation, thus diminishing the biodiversity in this place.
