Martha wants to grow tomatoes to make her own salsa. She has two varieties (an heirloom tomato and a roma tomato) of tomato plants and wonders which tomato will taste better as a
salsa. She grows them in the same type of soil with the same amount of light and gives them
the same amount of fertilizer and water. When the tomatoes are ready to harvest, Martha makes
salsa and decides the heirloom variety is the best.
What is the problem question ? What’s is the independent variable? What is the dependent variable ?

Problem question: Which tomato variety will taste better in making salsa?

Independent variable; Variety of tomato

Dependent variable: Taste of the salsa

Explanation:

The aim of every experiment is to solve a problem or answer a scientific question about an observed problem. The first step in the scientific method is to ask a question. In this experiment in which Martha is trying to check which variety of tomato is best for making her salsa taste great, the problem question is: Which tomato variety will taste better in making salsa?

- Independent variable is the variable in an experiment that is changed or manipulated. In this experiment, the independent variable is the VARIETY OF THE TOMATO.

- Dependent variable is the variable that is measured in an experiment or in other words, the dependent variable responds to changes to the independent variable. In this case, the dependent variable is the TASTE OF THE SALSA.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
