Answer:
The correct answer is b) placing medication drops in nose, eyes, or ears.
Explanation:
Instill refers to the action of pouring or introducing a liquid drop by drop on a mucosal surface or inside a canal or organic cavity, for therapeutic purposes. The most used instillations are: conjunctival, nasal, paranasal, atrial, laryngeal, tracheal, bronchial, bladder and urethral. The instillation can be carried out with the help of a simple common dropper or with an instrument called an instillator, which consists of a probe with a widened end and a syringe with a screw plunger; by activating the screw, the medicine is introduced drop by drop.
Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming
The answer to this question would be to be in a boat on a lake.
There are two kinds of waves during an earthquake, the P-waves and the S-waves. The P-waves or the Primary wave would be the fastest seismic wave between the two and literally would be the first one to arrive during an earthquake. The S-waves or the Secondary waves would be the next waves that arrive after the P-waves have passed. The difference between the two is that the Primary waves pass through all solid and liquid surfaces while the Secondary waves pass through only solid surfaces and not liquid surfaces. When you are in a concrete shelter underground, you would still be affected by the S-wave. The same goes when you are in a cement basement. When in a very tall building, you would feel it much more since the altitude gives more shake to the building unless the building is built to withstand earthquakes. Being in a boat on a lake would make you avoid the S-wave but not the P-wave.
