_____ processing starts at the very basic level of sensory receptors and works toward more complex levels of processing.
nevsk [136]

<u>Bottom-up processing</u> starts at the very basic level of sensory receptors and works toward more complex levels of processing.

Explanation:

Bottom-up sensory processing, a sensory perception process, is the entry or basic level of analysis of the senses which begins with an incoming stimulus that is detected by the sensory receptors in sensory organs and then begins the complex processing of sensory perception.

This process is initiated with a sensory data from which sensory information is integrated in the brain.  

The sensory photoreceptors of the eye present in the retina capture light as the visual data. This data is then transducted to electrical impulses and transmitted to the visual cortex in the brain, where the information in the data is processed that provides the visual experience .

dsp73

A model for a​ company's revenue from selling a software package is ​R(p)=-2.5p² + 400​p, where p is the price in dollars of the software. What price will maximize​ revenue? Find the maximum revenue.

Answer: p = $80,  R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x=\frac{-b}{2a}

R(p) = -2.5p² + 400

     a= -2.5  b=400

p=\frac{-(400)}{2(-2.5)}

         = \frac{-400}{-5}

        =80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

         = -16,000 + 32,000

         = 16,000

1. Prokaryote - A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.

Eukaryote - An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus.

2. Two cell structures found in both are a cell membrane and plasma membrane. (you can also use cytoplasm)

3. Two organelles in Eukaryotic cells are mitochondria, chloroplasts, endoplasmic reticulum, lysosomes. (List whichever two)

What are similar structures that evolved independently called?
Ilia_Sergeevich [38]

Answer:

Analogous structures

Explanation:

These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.
