Photoreceptors are responsible for visual phototransduction. They convert light into biological signals. In humans, rods, cone, and retinal ganglion cells are the 3 main photoreceptors.
Rods are narrow and are present throughout the retina. They are very sensitive, They can be triggered by a single photon also. They are responsible for the visuals we get in the low-light conditions.
Cons need a high number of photons, in order to produce signals. They are responsible for visualization of colors. 
Rhodopsin is the pigment molecule of the rod cells. It is very sensitive to the light, and enables visualization in dim lights.

There are currently three known types of photo receptor cells in mammalian eyes: rods, cones, and photosensitive retinal ganglion cells. The two classic photo receptor cells are rods and cones, each contributing information used by the visual system to form a representation of the visual world, sight.

Wittaler [7]

Answer:

Because factories were usually located in cities, industrialization went hand-in-hand with – urbanization. The industrial economy helped create robust growth in the United States for many decades. Plentiful manufacturing and industrial jobs meant that –workers could enter the job market making a good wage. But as the economy began to transform once more, from an industrial to a post-industrial system, the nature of work changed as well. –This led to a decline in industrial jobs: from 18 million in 1990 to –12.4 million by 2017.

Explanation:

a) Industrialization: This term refers to the development of industries, which is characterized by economic growth, more efficient division of labor, mass production, and the use of technological innovations to solve problems.  Industrialization was triggered by the evolution of capitalism and the agricultural revolution.

b) Urbanization: Is the outcome of a process that see the movement of the population from rural areas to towns and cities.  It is usually caused by industrial growth, availability of employment and social amenities, commercialization of activities, modernization, etc.

c) Industrial Economy: This is an economy characterized by the building of industries, where the factors of production are no longer limited to land, labor, capital, and natural resources, but include the use of technology and knowledge.

d) Post-Industrial System: Post-industrial system is an economic system of the period within an industrialized economy or nation witnessing a declining manufacturing sector and increasing activities in services, information, and research, resulting to de-industrialization.

Compare the benefits of natural change to ecosystems to the disadvantages.
Ronch [10]
Natural changes to the ecosystem refer to environmental phenomenon that occur naturally. Natural changes include floods, volcanic activity, hurricanes, droughts, and earthquakes. They can be destructive, but they also have advantages.
The benefit of the flood is for example providing nutrients to the soil that were lacking. Also t<span>here may be relocation of fishes and organisms living in water bodies, which improves the ecosystem.
Volcano threatens t</span>he people and animals in the area are threatened, but is has also some advantages, for example:<span>the soil becomes rich due to the nutrients from the volcano. 
</span>Hurricanes result in the destruction to infrastructure and loss of lives, vegetation, and livestock. The advantage is that it lowers the temperature and t<span>he wind will cause the topsoil to be distributed to areas in which it was lacking.</span>

What is the solution of StartFraction 1 Over c minus 3 EndFraction minus StartFraction 1 Over c EndFraction = StartFraction 3 Ov
Bingel [31]

Answer:

  • <u><em>All real numbers except c = 0 and c = 3.</em></u>

Explanation:

The equation is:

   \dfrac{1}{c-3}-\dfrac{1}{c}=\dfrac{3}{c(c-3)}

Since c - 3, c, and c(c - 3) are he denominators, none of them can be equal to zero:

  • c ≠ 0
  • c - 3 ≠ 0 ⇒ c ≠ 3
  • c (c - 3) ≠ 0 ⇒ c ≠ 0 and c ≠ 3.

Now you can multiply both sides of the equation by the common denominator: c (c - 3):

       c-(c-3)=3\\\\c-c+3=3\\\\0=3-3\\\\0=0

That means the equality is valid for all real numbers for which it is defined, which is all real numbers except c = 0 and c = 3.
