Sam's role on the software development team is a Software Quality Assurance.
<h3>What is SDLC?</h3>
SDLC is an abbreviation for software development life cycle and it can be defined as a strategic methodology that defines the key steps, phases, or stages for the design, development and implementation of high quality software programs.
In Computer technology, there are seven (7) steps involved in the development of a software and these include the following;
- Planning
- Analysis
- Design
- Development (coding)
- Testing
- Deployment
- Maintenance
In this scenario, we can reasonably infer and logically deduce that Sam's role on the software development team is a Software Quality Assurance because he his is saddled with the responsibility of identifying the system functions that must be validated and how to test new software.

Answer:
B.4.75
Explanation:
Buffer solutions are the solutions which can resist the change in the pH up to some extent. They are the solutions of either weak acid and conjugate base of it or weak base and conjugate acid of it.
The pH of a buffer solution can be measured by the equation known as Henderson–Hasselbalch equation.
pH=pKa+log[base]/[acid]
A good buffer that buffer which has its acid's pKa within one pH unit of desired experimental conditions.
Thus, desired pH = 5.3
Preferable pKa = 4.3 - 6.3
<u>Answer - B. 4.75</u>
True, you can because in Scratch, you actually can use an if statement block and use an if touching another sprite.
