(b) List two ways by which patching can be done.

(c) (i) Explain a design brief

(ii) List three methods of carrying out design investigations.

(iii) State two factors to consider when selecting the best solution from the generated possible solutions in designing.

(d) (i) What is the colour spectrum?

(ii) List the three primary colours of light.

(iii) Explain secondary colours. 

Answers 

(1) (a) Functions of protein in the body 

1) Provides body-building materials for growth and development.

2) Protein repairs worn-out tissues in the body.

3) They serve as a source of energy in the absence of carbohydrates and fats. 

(b) Ways by which patching can be done. 

1) Patching can be done by hand.

2) It can also be done by machine. 

(c) Design brief: Is a short written statement of what the designer intends to make as a result of a problem identified. 

(ii) Methods of carrying out design investigations. 

1) Interviewing people who are expertise in a given situation.

2) Visiting places for information.

3) Observing existing artefacts in use for ideas.

4) Reading from magazines, textbooks etc.

(iii) Factors to consider when selecting the best solution from the generated possible solution include: 

1) Tick the selected idea.

2) Ideas should be quiet different from one another and not a variation of a single theme.

3) Brief and clear explanation must be given. 

d) (i) Colour Spectrum: It refers to the beam disperse or division when white light pass through a prism. These produce seven main colours which red,yellow, orange, green, blue, indigo and violet (Rainbow colours). 

ii) the three primary colours of light are: 

1) Red

(2) Yellow.

(3) Blue

(d) Secondary colours: They are obtained by mixing equal amount of two primary- colours. Example Orange is obtained by mixing red and yellow. Blue and yellow give green and red and blue give violet.
