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.

Answer:
A) A tentative statement used to guide a scientific investigation is called scientific hypothesis.
As hypothesis is a proposed details of a phenomena, it can guide us in one way or another to carry out the scientific investigation.
B) Makes prediction about future events is scientific hypothesis.
Scientific hypothesis bases on the observation made predicts about future events, which could be either true or false.
C) Can be tested many independent researches is a scientific theory.
A scientific theory is developed when it has been passed through many researches and had gained acceptance too.
D) Both Scientific theory and hypothesis are based on the observations of the natural phenomena.
Firstly, an observation is made based on natural phenomena, which leads to questions, then research or study is carried out to answer these questions leading to the formation of a hypothesis which upon successful testing forms a theory.
E) Scientific theory is a well-established highly reliable explanation.
It a highly sustained explanation based on facts of nature, that are confirmed via a lot of experiments.

The hormone <u>adrenocorticotropin hormone</u> (ACTH). which is secreted by the adrenal cortex, causes the kidney to conserve <u>sodium</u> ions and excrete <u>potassium</u> ions and indirectly helps to maintain systemic blood pressure.
<h3>What are hormones?</h3>
Hormones are chemical messangers or substances which are produced by the body and released to the sites where they are needed in the body
So therefore, the hormone adrenocorticotropin hormone (ACTH). which is secreted by the adrenal cortex, causes the kidney to conserve sodium ions and excrete potassium ions and indirectly helps to maintain systemic blood pressure
