A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube to add carbon di oxide.
She blew in the test tubes to add the carbon di oxide to the tube which caused the distilled water to become more acidic so the phenol red turned yellow, and when she exposes the tubes to different set of color lights. So, in the presence of light it turn the water into red color, which shows the process of photosynthesis depending on the wavelength of different color.

She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube. Why did she blow into the tube? Multiple Choice
1) to add oxygen to the tube
2) to add carbon dioxide to the tube
3) to add carbohydrates to the tube
4) to add sodium bicarbonate to the tube
Answer:
Some members of each group unicellular (& some colonial & some w/multicellular stages in life cycle)
-Mostly microscopic
No germ layer present
Specialized organelles; (found nucleus single or multiple, no organs or tissues)
-Free living, mutualism, commensalism, parasitism all represented in groups
-Locomotion by pseudopodia, flagella, cilia, & direct cell movements; some sessile
-Some provided w/simple endoskeleton or exoskeleton, but most naked
-Nutrition of all types
-Aquatic or terrestrial habitat
-Reproduction asexually by fission, budding, & cysts and sexually by conjugation or syngamy (union of male & female gametes to form zygote)

Answer:
The most likely hormone released to Gina and her body deal with this dangerous and frightening situation is the adrenaline or epinephrine.
Explanation:
Adrenaline, also called <em>epinephrine</em>, is a <u>neurotransmitter</u> secreted to the bloodstream by the adrenal gland. <u><em>Under pressure or stress</em></u>, it is considered to be a survival hormone, as it <em>triggers physiological changes </em>in the body necessary to be fast or strong.
Adrenaline increases heart beating, blood pressure, stimulates breathing and dilation of the respiratory tract. It also increases glucose concentration in blood. It is responsible for the attack, defend or escape reactions.
