Antonio’s teacher challenged the class to create an experiment that tests how air temperature affects plant growth. Antonio’s group created their experiment using two green bean plants and one lima bean plant. During the experiment, the green beans were placed in direct sunlight. The lima beans were placed in direct sunlight with an aluminum cover. The table shows the proposed experimental design. The teacher handed back their assignment and asked the group to correct an error in their experimental design. What correction needs to be made?

Their experimental procedure was too advanced.

They should have only one tested variable.

They should have included another type of bean.

There was no outc0me variable.

Just give me a 5 stars and a thanks

Explanation:

plz

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
