What caused natural selection among peppered moths of Manchester England?
Alexus [3.1K]
The natural selection among peppered moths of Manchester, England can be mainly attributed to to the abruptly increasing levels of Air Pollution in England as a result of thriving Industrial Revolution In the U.K.

Soot from power producing factories, etc resulted in complete eradication of lichens in the flora of the surrounding region.

The frequency of the newly evolved peppered moth increased as the dark colour was beneficial in a polluted environment like in Manchester.

Which nerves are the hair cells in contact with?
AlekseyPX

Answer:

Auditory nerve

Explanation:

Hair cells form synapses with bipolar neurons whose axons form the auditory nerve. Tips of the outer hair cells are attached directly to the tectorial membrane. When the inner hair cells move they make contact with the overhanging tectorial membrane

Fun fact: Hair and nials are made out of the same things!

Briefly describe how lateral inhibition increases apparent contrast at edges. In your response be sure to discuss the role of li
rusak2 [61]

Answer and Explanation:

The retina covers the internal phase of the eye. It characterizes by its complex interaction between many morphologically and functionally different cells, which are located in many layers. The principal processing mechanism in the retina is lateral interactions among cells, and the most common lateral processing is lateral inhibition.

Photoreceptors are those cells that receive the light and translate the luminous signal into an electrical signal. These are the cones and sticks.

The horizontal cells intervene in the lateral spatial interaction between photoreceptors.      

Bipolar cells receive information from the photoreceptors and from the horizontal cells and transmit it to the most internal layers in the retina.

The retina is stratified into five layers. One of these is the external plexiform layer, a contact zone between photoreceptors, horizontal cells, bipolar cells, and other cells.    

In the vertebrates´ retina, the lateral inhibition is produced for the first time in the external plexiform layer, through the horizontal cells. These cells connect to photoreceptors, other horizontal cells, and bipolar cells. The connection between horizontal cells might reduce or amplify the photoreceptor answer, and this last one is transmitted by the bipolar cells to the interior of the retina. In photoreceptors, there are two connections to horizontal cells, a direct connection, and an indirect one. The connection between photoreceptors, horizontal cells, and bipolar cells is known as lateral inhibition. By this inhibition, photoreceptors allow the contrasting perception in an image. Lateral inhibition allows discriminating one stimulus from other stimuli, by enhancing contrast and definition. The inhibitory modulation is produced by the inhibitor neurotransmitter GABA.The spacial extension of lateral inhibition changes according to the adaptation to light. Gap junction between horizontal cells and between photoreceptors and horizontal cells might vary with the amount of light.
