Answer: Option A

Explanation:

The main purpose of the breathing by nose is to provide the optimum air quality which is required by the body.

The air that enters the nasal passage is moisten and heated when it passes through the nasal cavity.

When it travels through the passage the pathogens are killed by the mucous that lies in these area.

In this way, the air is filtered by the nasal passage. Hence, the correct answer is option A.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt wat
serious [3.7K]

Answer:

See the answer below

Explanation:

<em>Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.</em>

Bozo is adapted to living in salt waters. <u>If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die</u>. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.

The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence,<u> it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration</u>.
