Epinephrine triggers a direct signal transduction pathway.
I know this because when epinephrine binds to it's receptor example on a muscle cell,this is known as a type of G protein -coupled receptor,signal transduction cascade is triggered and this involves the production of a second messenger molecule cyclic AMP(cAMP).
Epinephrine also know as Adrenaline or sus-phrine.
It is a vasoconstrictor,broncho dilator and a sympathetic stimulant.
It constricts the peripheral abdominal organs as well as a stimulating the heart beat thereby raising the blood pressure,it also relaxes the spasms of the bronchial muscles thereby promoting ventilation of the lungs.
Answer:
<em>The sample size is too small.</em>
Explanation:
<u>The process of elimination helped me find this answer. </u>
It is possible to keep the conditions the same.
there are only 2 plants and one control, that's obviously not a lot.
and controls can be used on more than studying animals.
<u>When using the scientific method you can use as many test subjects as you can so it can help you confirm. two plants are not a lot. </u>

<em>I've also had a teacher confirm that this is the correct answer. </em>

Answer: change from one form of energy to another
Explanation:
As the name implies, Energy transformation refers to the conversion of one form of energy to another, such that energy is always conserved.
For instance:
- an electric pressing iron convert electrical energy to heat energy;
- a solar panel convert solar energy to electrical energy etc
All these are examples of energy transformation in nature.
Answer:
Bob can use Lugol to dye or stain the potato tissue and get to see the cells.
Explanation:
After viewing the slice of potato under the microscope, Bob can perform dyeing using Lugol to improve the vision and get to differentiate the cells.
All he needs to do is to add a few drops of Lugol between the glass slide and the coverslip, without taking this last one out. He needs to cover the whole potato slice with Lugol.
Once the tissue is covered with Lugol, Bob can eliminate the excess of the liquid, and then view the slide again under the microscope.
- At 4X, Bob will see little violet spheric structures that are conglomerated.
- At 10X and 40X, Bob will be able to discriminate each dyed cell. At this point, he will be able to see the nucleus, cytoplasm, nuclear membrane, and cellular wall. He will also see amyloplasts (the place where the cell storage starch) in the interior of the cells.
