The doctor examined her external ear canal and tympanic membrane with an otoscope. An otoscope is an instrument used to visually examine the external ear canal and tympanic membrane. Eardrum or tympanic membrane is a thin layer of tissue in human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles, which are tiny bones in the tympanic cavity.

✅A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek (halas) 'salt' and φυτόν (phyton) 'plant'. An example of a halophyte is the salt marsh grass Spartina alterniflora (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species.The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity.
Proteins have up to four levels of organic structure.
1.Primary structure - the linear arrangement of amino acids.
2. Secondary structure - areas of folding or coiling within a protein.
3. Tertiary structure - the final three dimensional structure of a protein.
4. Quaternary structure - non covalent associations that bind multiple polypeptides into a single larger protein. E.g. hemoglobin has four polymers, two alpha and two beta chains. They are non covalently bound to each other to form a single large protein - hemoglobin.
The major function of the large intestine is to absorb water. So i would go with two; reabsorption of fluids. Sorry if this is wrong.
