<span>This organelle is the nucleolus.
The nucleolus is made of proteins, DNA, and RNA. They form around specific regions of the chromosomes called nucleolar organizing regions. These regions of the chromosomes contain some the genes needed for ribosome production.</span>
The tympanic membrane is a patch of skin behind a frog's ear that allows it to hear on land and underwater
So basically, it's like an eardrum for a frog
Hope this helps

Answer:
The analysis of protein structure by frozen electron microscopy can be divided into three processes:
1. Sample preparation: the biomacromolecule sample is frozen rapidly in liquid nitrogen, and the water in the macromolecule exists in the form of glass.
2. Data collection: irradiate the sample and the ice near the sample with low energy electron beam, and record the scattered signal with detector.
3. Three dimensional reconstruction to build protein model: three-dimensional structure of protein is built by two-dimensional projection from different angles.
