SPI 2 – Evaluate a protocol to determine the degree to which an engineering design process was successfully applied.
Design analysis – The design analysis process is a methodical approach that is used by engineers, architects, and designers to solve problems. Most designers use some process for problem solving. Most of the processes are based on a logical system of experimentation, data gathering, and record keeping. The design process is often based on consumer demand for the product. A typical design analysis process has these elements:
problem identification – identify all that is known about the problem (historical and background info., economic requirements, manufacturing or construction processes available, and market info.; list known limitations and specify the desirable features)
preliminary ideas – record all ideas in notes, written descriptions, and sketches – these may be originals or modifications
refinement – the designer takes several preliminary ideas and reduces them to two or three that are the best; these ideas are then refined with more detail. Preliminary drawings often have the major dimensions, physical properties, shape, and weight characteristics.
analysis – the analysis of the problem is a very important part of the design process. After the designer chooses the best ideas, he is ready to consider cost, strength, function, etc. Testing and data collection help determine the best results (design). Physical properties like material, shape, size, color or texture are also considered.
decision – selecting the best design may be a joint decision between a team of designers, engineers, and manufacturing or construction leaders. Positives and negatives are considered.
implementation – formal drawings are made, specifications are written and the product is manufactured…in some cases a prototype is made for final testing before being released for mass production.
SPI 3 – Evaluate the overall benefit to cost ratio of a new technology.
A BCR is the ratio of the benefits of a project or proposal, expressed in monetary terms, relative to its costs, also expressed in monetary terms.
In its simplest form, benefit cost ratio is a figure that is used to define the value of a project versus the money that will be spent in doing the project in the overall assessment of a cost-benefit analysis.
To create a benefit cost ratio example we’ll use Widget Corp. as our fictitious business. Widget Corporation’s top account executive has an idea for a new widget that will revolutionize the widget industry. The total cost to plan, develop and produce the widget is $55,000. Once the production line has been set up, the revolutionary widget sells like hotcakes and produces record net profits for Widget Corp. of $500,000 for the year. Using the formula listed above, we can figure the benefit cost ratio. 500,000/55,000 = 9.09 The final outcome of $9.09 is the dollar representation of a $9.09 return for every $1.00 invested in the revolutionary widget. After one year of sales, the revolutionary widget paid for itself almost ten times.

12 it’s haploid number is _________. These numbers refer to the number of _________________ in the nucleus.
Cytokinesis (Cytoplasmic Division). The basic point of cytokinesis is to divide the cytoplasm of the original cell such that each of the nuclei from mitosis gets roughly equal amounts of cytoplasm and the organelles each new cell needs. Cytokinesis is different for plant and animal cells. In plant cells a so called cell plate forms roughly equidistant between the ends of the old cell.
This cell plate consists of new cell membranes for each new cell. Between these membranes the cell walls for each cell are laid down.

SPI 8 – Compare and contrast active and passive transport.
Active transport –
Passive transport –
Concentration gradient –
Facilitated Diffusion/Passive transport
Facilitated diffusion involves the use of a protein to facilitate the movement of molecules across the membrane. In some cases, molecules pass through channels within the protein. In other cases, the protein changes shape, allowing molecules to pass through. Additional energy is not required because the molecule is traveling down a concentration gradient (high concentration to low concentration). The energy of movement comes from the concentration gradient.
Active transport is used to move ions or molecules against a concentration gradient (low concentration to high concentration). Movement against a concentration gradient requires energy. The energy is supplied by ATP which is released by breaking a phosphate bond to produce
ADP + P i
+ energy The Sodium-Potassium Pump The sodium-potassium pump uses active transport to move 3 sodium ions to the outside of the cell for each 2 potassium ions that it moves in. It is found in all human cells, especially nerve and muscle cells.
One third of the body’s energy expenditure is used to operate the sodium-potassium pump.
One phosphate bond in the ATP molecule breaks, releasing its energy to the pump protein. The pump protein changes shape, releasing the sodium ions to the outside. The two potassium binding sites are also exposed to the outside, allowing two potassium ions to enter the pump.
When the phosphate group detaches from the pump, the pump returns to its original shape. The two potassium ions leave and three sodium ions enter. The cycle then repeats itself.

SPI 4 – Determine the probability of a particular trait in an offspring based on the genotype of the parents and the particular mode of inheritance. (p. 268)
I remember Incomplete Dominance in the form of an example like so:
RED Flower x WHITE Flower ---> PINK Flower
With incomplete dominance , a cross between organisms with two different phenotypes produces offspring with a third phenotype that is a blending of the parental traits. First let me point out that the meaning of the prefix "co-" is
Cooperate = work together. Coexist = exist together. Cohabitate = habitat together.
Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers & the recessive allele (w) codes for short whiskers.
1) What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one parent is homozygous dominant and the other one is heterozygous?
2) If one parent seal is pure long-whiskered and the other is short-whiskered, what percent of offspring would have short whiskers?

Natural selection –
Homologous structures –
Common descent –
ALL vertebrate limbs are put together this way, regardless of their use. Clearly there is no analogous similarity between a bat's wing and a horse's leg, and the extreme difference in uses of the two makes the underlying similarity seem unusual. These types of similarity are called homologous and are very interesting indeed.
SPI 2 – Recognize the relationship between form and function in living things.
Darwin’s process of natural selection has four components.
Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring. On the other hand, some traits show little to no variation among individuals—for example, number of eyes in vertebrates.
Inheritance. Some traits are consistently passed on from parent to offspring. Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.
High rate of population growth. Most populations have more offspring each year than local resources can support leading to a struggle for resources. This struggle creates competition for resources. Each generation experiences substantial mortality.
Differential survival and reproduction. Individuals possessing traits well suited for the struggle for local resources will contribute more offspring to the next generation.
