1. The bird has to adjust where it doves in for the fish because the light is refracted by the water, making it look like the fish is in a different position than it is.
2. The clock is reflected in the mirror, which sends each part of the image straight back.
4. Your first part is correct. The second part: The plant would look dark brown or black and red light. Red light has no green wavelengths to reflect, and the red light would be absorbed by the leaf, making it appear almost black.
LMK if you have questions.
Because it has more protons than electrons. Protons are positive so if there is more of them than electrons, the ion will have a positive charge.
Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition.
Brainest please thank you
Answer:
The correct answer is :
1) Fehling's test,
2) Tollen's test
Explanation:
1. Fehling's Test is the test that confirms the presence of aldehydes by the Fehling solution that contain copper ion with tartrate ions in NaOH solution. The color of the solution is blue due to presence of copper ions. In this test aldehydes are confirmed by the reduction of the blue solution to a insoluble precipitate of copper oxide red color while in presence of ketones there is no change.
2. Tollen's test is also a test that help in identifying the presence of aldehyde as the Tollen's reagents oxidizes aldehydes where ketones as they lack hydrogen in them.
Thus, the correct answer is : 1) Fehling's test,
2) Tollen's test.
