If our visual perception depends only on the feature detectors in the visual cortex, what would we see?
Anika [276]

The sophistication of the visual cortex can be simplified through understanding that the neurons found in this region are distinguished by the kind of stimulus that each detects.

There are three major groups of feature detectors in visual cortex. These includes simple cells, complex cells and hypercomplex cells. The simple cells are the most specific since it responds to the geometric characteristics of the stimulus such as the lines of particular width, orientation, angle and position within the visual field. The complex cells are similar to simple cells. What differentiates one from the other is that they respond to the proper stimulus in any position within the receptive visual field. In addition, some of the complex cells respond to particular lines or edges moving in a specific direction opposite the receptive field. Lastly, the hypercomplex cells are responsive to the specific length of the lines. It is believed that the information from all feature detectors conjoin in to result in the visual stimulation perception.

How do cells differentiate from each other? What sends a cell the message to become one kind of cell rather than another type?
tester [92]
Cell differentiation is a process by which stem cells give rise to different type of cells with different functions and located in different locations. it is is true that all cells in a particular organism have same composition of genetic material. however they perform different function because of the process of cell differentiation. cell differentiation results from expression of some genes inside the cell the dictate what type of cells should be synthesized.after gene expression proteins produced send the message to stem cells to indicate the type of cells to be manufactured.

A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatogr
Amiraneli [1.4K]

Answer:

as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.
