The receptive field of this type of cell in the striate cortex is made up of a large number of receptive fields from neurons in the LGN. Additionally, these cells respond to light at specific orientations and locations, and thus are best in responding to things such as lines and edges. A. Complex
B. Ganglion
C. Bipolar
D. Simple

Simple cell

Explanation:

Simple cells are found in primary visual cortex and are made up of large number of receptive fields from neurons and the respond to light at specific Orientation and oriented edges. The cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. The simple cells respond to stimuli with some particular orientations to objects within their receptive fields. Receptive fields comprises of sensory receptors in the sensory neurons that draw out neurosonal responses when there are stimulated

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
