WebHeat stress during seed maturation significantly reduced seed size and quality. Polyamines, especially spermidine (Spd), were reported to be closely related to seed development and plant heat tolerance. Stress-associated proteins (SAPs) also played a critical role in plant heat resistance, but the relationship between Spd and SAPs in improving rice tolerance … WebSPM PAPER 3 (mainly applicable to Biology and Chemistry) SPM Biology Paper 3 (applicable to Paper 3 Chemistry but not so for Physics P3 Guidelines on how to answer Paper 3 questions.

WebDuring an experiment of mechanics or physics, it is best to use scientific diagrams. For these subjects, experiments largely depend on the process. A correct setup and procedure can give an accurate result. Therefore, to learn about the tuning fork resonance experiment, the students should use scientific diagrams. However, it may be challenging ... Web3. As the centripetal force went up, the velocity went up as well. 4. The velocity of the object increases as the radius of the circle increases. 5. The velocity of the object goes down as the mass of the object moving increases. 6. The centripetal force would have to go up. This is because the radius of the circle. WebThis experiment explores the atomic physics of both isotopes of natural rubidium. The rubidium atom is an ideal model system to study: its energy states, in an externally applied uniform magnetic field, can be understood using a semi-classical model. ...
