is the potato a living organism? is it alive? how do you know?

In the early 1800s, potatoes became the main food staple for the people of Ireland. In 1845, a fungus native to South America, Phytophthora infestans, began to infect potato plants, causing potato blight and making the tubers inedible. Over the next several years, most of the potato plants in the country were destroyed by this invasive species. Which of the following statements correctly explains why the Irish potato famine occurred? The arrival of ships from South America led to human introduction of the disease. A drought across Ireland in 1844 led to more damaged potato plants that were susceptible to infection. An increase in trade with other European countries led to the introduction of plants that were already infected with the fungus. Ireland's climate became closer to that of South America, which allowed the fungus to infect potato plants and reproduce.

You are curious to know whether the amount of sugar (food) provided to yeast impacts how much waste gas is produced. To help answer this question, you set up an experiment similar to the one you performed in lab. However, this time, you use four flasks instead of two.    In Flask 1 you add 1/4 teaspoon of sugar, in Flask 2 you add 1/2 teaspoon of sugar, in Flask 3 you add 1 teaspoon of sugar, and in Flask 4 you add no sugar.   You add 1/2 teaspoon of yeast ("unlabeled sample") and 20 mL of lukewarm water to each flask.   You place a balloon on top of each flask. After 30 minutes, you measure the circumference of each balloon to determine how much gas was produced   efer back to this experiment to answer questions 1-7.   ________________   A) What were the treatment groups in this experiment? B) Which group was the control group?
