In an experiment, a group of scientists want to test the effects of humidity on plant growth. The scientists expose the plants in the study to a range of different humidities to measure plant growth over a specified amount of time. In this experiment. What is the independent variable? Please help me ASAP

A) Plant growth
B) Humidity
С)Fertilizer
D)None of the above

The correct answer is - option B) humidity.

Explanation:

Independent variable is the variable in a scientific experiment that can be modify or change in order to find out the response and analyse the response of dependent variable.

In this experiment the independent variable is humidity as it is changed in order to find out and study plant growth response by the effect of humidity.

Thus, the correct answer is - option B) humidity.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
