Answer:
The technique is known as "staining"
Explanation:
Staining is a technique used to enhance the color contrast of the microscopic samples when observed in the microscope especially in the microbiological samples.
In the given question, when the staining technique is used to identify the sample then staining procedure is followed in a process where the samples can be identified on the basis of the color contrast which is in the case of gram staining.
The gram staining is used to identify the bacteria on the basis of color as the bacteria which appear blue in color are called gram-positive and the bacteria which appear red in color are gram-negative bacteria.
Thus, staining is the correct answer.
Vascular tissues are used for transport, the xylem carries water and the phloem carries food.
1. a. <span>is a possible explanation for events using prior knowledge
An inference </span><span>is a possible explanation for events using prior knowledge, therefore, inference is an educated guess which can provide a logical reasoning to an object, phenomenon or circumstance.

</span>Since the amount of time can't clearly be controlled but only observed the other factors which is water, soil and type of plant can be manipulated in the study.
Answer:
They showed how organic molecules could be made from Earth's early atmosphere.
Explanation:
Miller-Urey experiments were based on the ides of a-bio-genesis. It means the production of life through the non biological factors. In this experiment it shows that life can be produced through chemicals and molecules that were found in the early form of earth and is composition.
It kind of gives off to the evolution theory and the amino acids which are the building blocks of life and were given rise to during the simulation.
