Tuesday Trivia Answer – August 28, 2018

Just to recap last week’s Tuesday Trivia post: Due to rising levels of ______ (fill in the blank) ________, some species of fish are slowly losing their ability to smell.

Answer: Carbon dioxide (CO2)

As the levels of carbon dioxide rise in a body of water, carbon dioxide converts to carbonic acid which increases the acidity of the water. It turns out, acidic conditions reduce the sensitivity of the olfactory sensors in a fish (i.e. the nerves responsible for being able to smell).

As we’ve demonstrated with posts and trivia questions in the past, protecting, testing and treating our fresh water sources is important to the health of everyone. Read through this helpful infographic for a quick review of the potential contaminants that could find their way into our water sources.

Tuesday Trivia – July 31, 2018 Answer

For those who saw last week’s Tuesday Trivia post, read on for the answer you’ve been waiting for.

For those who are unfamiliar with these posts, every other Tuesday, a trivia question will get posted to allow us to test our wits and expand our horizons.

As a reminder, the question that was posed last week:

Imagine shrinking the Earth’s water supply down to 100 liters. The volume of fresh, usable water would be roughly ____(fill in the blank)____ liters.

Answer:  0.003 liters!

This may seem like a surprising answer, given that water is everywhere on the Earth – glaciers, lakes, rivers, streams, oceans and aquifers.  There’s even moisture in the atmosphere!  However, you must first take into account that most of the water on Earth (roughly 97%) is contained within our oceans which makes it salt water, not fresh water.  A significant portion of the remaining fresh water is tied up in glaciers, too polluted for safe consumption, or is buried too deep under the Earth’s crust.  Obviously, we could make attempts to clean up our polluted waters or pull fresh water out of the Earth, but those quickly become cost-prohibitive options for the planet’s growing population.

Clearly, fresh water is a precious resource for us. Click here to learn more about methods for monitoring and protecting our water sources.

Tuesday Trivia – July 17, 2018 Answer

For those who saw last week’s Tuesday Trivia post, read on for the answer  you’ve been waiting for.

For those who are unfamiliar with these posts, every other Tuesday, a trivia question will be posted to allow us to test our wits and expand our horizons.

As a reminder, the question that was posed last week:  Cucumbers and _____(fill in the blank)_____ both consist of 95% water.

Answer:  JELLYFISH!

Believe it or not, jellyfish are basically a nervous system and a digestive system with tentacles. As they lack bones, blood, a heart, a brain and many other muscles and organs, they require water to survive and water currents to transport them.

For a jellyfish, water is a crucial component for their survival. While humans don’t require water for our daily movements and transport, it is crucial for our survival as well.  Click here to learn more.
