Sarah is collaborating on an experiment in her an anatomy and physiology class. she and her partners lower electrodes into a cat's cortex. they place the electrodes perpendicular to the cat's cortex and every neuron they encounter has its receptive field at about the same location on the retina. this is a replication of an experiment demonstrating that the striate cortex is organized into

The correct answer is "location columns".

Explanation:

In a notorious experiment, David Hubel and Torsten Wiesel examined the properties of neurons by using microelectrode recordings. In their findings, these two scientists discovered that the striate cortex is organized into location columns and that all edge orientations were roughly equally represented in visual cortex. Sarah is doing a replication of this experiment, using electrodes perpendicular to the cat's cortex.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
