Praxis - Art 5134 Exam Questions And Answers Deviation from the normal or usual. Unexpected, unusual. Unexpected situation or quality - ANS anomaly In painting, the term Local color refers to the natural color of an object unmodified by adding light and shadow or any other distortion. Local color is best seen on a matte surface, due to it not being reflected, and therefore distorted. *** - ANS Local color A cylindrical drawing tool, or paper stump, tapered at the ends and usually...

What is the point at which load would cause an initial indication of a permanent distortion called? - Answer yield strength True or false: Tensile strength is measured by the resistance of a material to a force that would tend to pull it apart. - Answer True True or false: The property of metal to return to its natural shape is called ductility. - Answer False

Gel Electrophoresis Questions and Answers Already Passed What property of DNA allows it to migrate towards the positive electrode during gel electrophoresis? DNA is negatively charged due to its phosphate backbone, causing it to move towards the positive electrode when an electric field is applied. In gel electrophoresis, what role does the gel matrix play in the separation of molecules? The gel matrix acts as a sieve, allowing smaller molecules to pass through more easily while re...

Welding Level 1, Module 6 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the purpose of using a backstep technique when welding? The backstep technique helps to control distortion and reduce the buildup of heat in a weld by alternating the direction of the weld. Why should you avoid welding in windy conditions? Wind can blow away the shielding gas, leading to contamination of the weld pool and affecting weld quality. What is the benefit of using ...

Welding Skills Chapter 16 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the main benefit of using a weave pattern in welding? To ensure uniform heat distribution and better penetration in wider joints. Why is it important to maintain the correct welding speed? To achieve consistent bead shape, prevent overheating, and avoid excessive heat distortion. What is a "burn-through" in welding? When excessive heat causes the base metal to melt t...

Welding Level 2, Module 9 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What causes weld porosity, and how can it be avoided? Porosity is caused by trapped gas in the weld pool, which can be avoided by ensuring proper shielding gas flow and cleaning the base material. How does the welding speed affect the weld bead profile? The welding speed affects the bead size and shape; too fast can lead to undercut or incomplete fusion, while too slow can cause exce...
