Answer:
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

C. FALSE
D. FALSE
Explanation:
A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
