Trivia Questions Over Agriculture

Explanation
The statement "The Roselle tea plant reduces blood pressure" is true. Roselle tea, also known as hibiscus tea, has been found to have a positive effect on blood pressure. Studies have shown that regularly consuming Roselle tea can help lower both systolic and diastolic blood pressure levels. This is due to the presence of bioactive compounds in the tea, such as anthocyanins and flavonoids, which have been found to have antihypertensive properties. Therefore, drinking Roselle tea can be beneficial for individuals looking to manage their blood pressure levels.

Explanation
The correct answer is Hydroponics and Greenhouse. Hydroponics refers to a method of growing plants without soil, where the plants are instead grown in a nutrient-rich solution. A greenhouse, on the other hand, is a structure made of glass or plastic that provides controlled environmental conditions for plant growth. Therefore, using hydroponics in a greenhouse would allow for optimal control over the growing conditions, such as temperature, humidity, and light, resulting in healthier and more productive plants.

Explanation
Frogs have the ability to survive being frozen due to a process called cryopreservation. During winter, frogs can enter a state of hibernation known as freeze tolerance. Their bodies produce high levels of glucose, which acts as a natural antifreeze, preventing ice crystals from forming and damaging their cells. As a result, their vital organs and tissues are protected, allowing them to survive the freezing temperatures. Once the weather warms up, the frogs thaw out and resume their normal activities. Therefore, it is true that frogs can still live if they are frozen.

Explanation
The statement "We are bringing 14,000 gallons of water just to grow plants" suggests that a large amount of water is being used solely for the purpose of growing plants. However, the correct answer is False, indicating that this statement is not true. This implies that either the amount of water being used is not 14,000 gallons, or the water is being used for purposes other than just growing plants.
