Document Summary

Plants go through generational changes throughout their lives. It because their life cycle has two stages, this is known as generation alternation. A haploid gametophyte and a diploid sporophyte are the multicellular stages. Of diploid animals, produced haploid gametes that give rise to diploid offspring after development and fertilization. Pollen grains germinate and produce pollen after. The tube will be used to transport sperm cells to pollination. the ovule. cell. When the sperm cell reaches the ovule, double fertilization occurs. An embryo will be formed along with a nourishing. The embryo will develop into a seed as it is fed. Plants with spores include ferns, mosses, and liverworts. The life cycle of spore plants is distinct. A parent plant releases tiny spores with unique sets of chromosomes. These spores lack an embryo and food stores. The spores are fertilized away from the parent, usually in a damp environment.

I need help solving these questions for my software class:

12. Match each term with its definition

Word list: documentation, evolutionary prototype, GUIs, fourth generation, information gathering prototype, libraries, Lips and Prolog (5GLs), prototype, prototyping approach, short-term solution

Term Definition

	Programming languages often used in information gathering prototype development
	Usually involves only a small team of programmers and one or more users
	Type where the prototype becomes the full working program
	Term used to describe the scale and budget for most prototyping projects
libraries	Collections of reusable code often used to speed up prototype development
Lips and Prolog (5GLs)	Languages often used in the development of prototypes of both kinds
GUIs	Favoured interface for prototype development
information gathering prototype	Prototypes developed to gather information that can be used in another development
documentation	Stores critical information for future maintenance
prototype	A working model that can be evaluated by users

14. Complete the Methods of Implementation table, using the information provided below.

One section of the organisation uses the new program and all other sections continue with the old program until a decision is made to put the new program into place across the whole organisation	One or more tasks of the new program are gradually implemented until the new program takes over all tasks of the old program
The old and the new program work together	The new program immediately replaces the old program

Method	Description	Diagram (draw it yourself)
Direct Cut Over	The new program immediately replaces the old program
Parallel Implementation	The old and the new program work together for a period of time
Phrased Implementation	One or more tasks of the new program are gradually implemented until the new program takes over all tasks of the old program
Pilot Implementation	One section of the organisation uses the new program and all other sections continue with the old program until a decision is made to put the new program into place across the whole organisation

A new sensor to detect bloodborne biomarkers is in development. The sensor uses enzymes immobilized on the surface of a flat strip (0.1cm X2cm) of polymer material to collect the biomarkers for increased detection. The enzymes rapidly convert the biomarkers into a secondary product that can be detected more easily. In an experiment, you collect blood from a patient that contains the biomarker and gently flow it over the sensor material at a velocity of 2 cm min". The flow is parallel to the long axis of the strip and the temperature is maintained at 37°C.

If the diffusivity of the biomarker in blood was determined to be 5.87 X 10^6 cm^2/s, what is the mass transfer coefficient for this process?

Your data indicates that 0.023 milligrams of biomarker were collected in 1 hour. Based on this measurement, what is the biomarker concentration in the blood?
