Bromothymol blue (BTB) is a chemical indicator for carbon dioxide (CO2). In the presence of carbon dioxide (CO2), BTB turns from blue to yellow. An aquatic plant was placed into two test tubes containing BTB, and the test tubes were closed with a stopper. Then, one test tube was placed in the dark, and the other test tube was placed in direct sunlight. The test tube in sunlight stayed blue indicating no CO2 was present, while the test tube in the dark changed to yellow. Which statement best explains why the solution in the test tube placed in the dark changed to yellow?
Answer:
Explanation:
Although no options was given, the explanation below should give detail explanation.
The Chemical reactants( internal factors) for the process of photosynthesis are C02 and H20, and enzymes. Other external factors are sunlight and chlorophyll.Therefore for a plant to undergo photosynthesis these reactants must be present in the presence of sunlight.
In the present scenario the plant in the test tube exposed to sunlight must used up the C02 with water and exposed sunlight to produce O2 -the by products and CHO,Protein and Lipids in plants.
Since the C02 has metabolised,no CO2 would be present in the test tube of the plant and the water, hence BTB is negative,blue- no C02.
However,the plants in the dark lacks the supply of sunlight therefore no photosynthesis could occur.Consequentially the C02 is not metabolized,and its concentration is high in the leaf in the test tube placed in the dark.This is indicated as yellow positive by the BTB which change from Blue to yellow.

Three red square pieces of wood, four yellow square pieces, and five blue square pieces are put into a cloth bag. Four red round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
The question is incomplete. Here is the complete question.
Three red square pieces of wood, four yellow square pieces, and five boue square pieces are put into a cloth bag. four re round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
What are the chances that the piece is red round or blue round piece?
a. Cannot be determined
b. 1 chance out of 3
c. 1 chance out of 21
d. 15 chances out of 21
e. 1 chance out of 2
Because:
a. 1 of the 2 shapes is round
b. 15 of the 21 pieces are red or blue
c. There is no way to tell which piece will be picked
d. Only 1 of the 21 pieces is picked out of the bag
e. 1 of every 3 pieces is a red or blue round pieces
Answer: b. 1 chance out of 3
e. 1 of every 3 pieces is a red or a blue round pieces
Explanation: Inside the bag, there will be:
Total of squares: 3 + 4 + 5 = 12Total of round: 4 + 2 + 3 = 9Total of pieces inside the bag: 12 + 9 = 21The question is asking for a round red piece. The probability of that happening is
P(r) = [tex]\frac{4}{21}[/tex]
And a blue round piece:
P(b) = [tex]\frac{3}{21}[/tex]
It is a "OR" probability, so:
P(r or b) = [tex]\frac{4}{21} +\frac{3}{21}[/tex]
P(r or b) = [tex]\frac{7}{21}[/tex] or [tex]\frac{1}{3}[/tex]
Which means 1 out 3 pieces taken out of the bag will be red or blue.

Which of the following best defines the process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment?
Group of answer choices
A. digestion
B.homeostasis
C. excretion
D. disequilibrium
Answer:
Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).
Explanation:
All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.
The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means all the processes aimed at preserving the balance and fulfilling the organic functions properly.
The other options are not correct because:
A. Digestion is the process by which nutrients are converted into small molecules that are easily absorbed by the body.
C. Excretion is the process of eliminating waste from metabolic and organic processes.
D. Disequilibrium is the term applied to the failure or loss of ideal conditions or balance.

What best describes the relationship between the two sets of reactions of photosynthesis, which are the light-dependent reactions and the light-independent reactions?
Answer:
The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions.
Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.
What are Light-dependent and independent reactions?Light-dependent reactions which convert light energy into chemical energy, so the goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to form ATP and NADPH, while these two energy storage molecules occur which is used in light-independent reactions.
Light-dependent reactions occur in the thylakoid membrane that use light energy to make ATP and NADPH while in light-independent reactions or the Calvin cycle where electrons activated from light-dependent reactions provide energy to make carbohydrates from carbon dioxide molecules.
Thus, Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.
