Answer:
Nylon and Spandex (Lycra).
Explanation:
These materials are designed to fit the body, with nylon drying more quickly than other types of fabrics, and Spandex being commonly found in swimming and sports apparel due to its elastic qualities. Both fabrics also wick moisture away and dry rapidly.
With high capacity and enhanced flexibility, nylon and Spandex provide a snug fit to the body and can retain their shape during various activities, making them ideal for swimming.
This explains why these materials are suitable based on the situation given.
An r-selected species has a significantly faster reproductive rate compared to K-selected species.
The focus of r-selected species is on quick maturation and reproduction. They are likely to breed during short periods when water supply is available, thus enhancing their survival chances.
Conversely, K-selected species prioritize nurturing their young and tend to reproduce later. Due to the longer maturation time before breeding, by the time K-selected species are ready, the water supply may be depleted, leading to lower survival odds.
Hope this clarifies!

Greetings!
The result is:
The new volume is: 
Rationale:
Because the temperature remains constant, we can apply Boyle's Law to solve this issue.
Boyle's Law stipulates that:

Where,
P is the gas's pressure.
V is the gas's volume.
According to the information provided:

Let's put the values into the equation:


Consequently, the new volume is: 
Wishing you a lovely day!
