The pH indicator bromothymol blue is blue in an alkaline solution and yellow in an acidic solution. A slight increase in acidity, such as CO2 gas is added, causes a solution with the indicator to change from blue to yellow. A solution with the indicator would be most likely to turn from yellow to blue in which combination of factors exist

Answers

The question is incomplete, however, the missing part is given as below:

A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.

Answer:

The correct answer is - B. Water plants in the solution are placed under a bright lamp.

Explanation:

As we know adding carbon dioxide in as solution result in the change of its acidity this is the result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.

Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.

What is cellulose? Why is it indigestible for most animals (including humans)?

Answers

Answer:

a cellulose is the main substance that makes up the cell walls and fibers of plants

Explanation:

cellulose is ingigestible to most animals because animals do not have the enzymes needed to hydrolyze the glycosidic linkages between the monomer units

The correct answer is - cellulose is a polysaccharide that is indigestible for most animals as they lack bacteria that produce enzyme help in digestion of cellulose.

Cellulose is a structural polysaccharide that is present in most of the plant's structure as present in the cell wall of plant cells and provides support and help in standing in an upright position.

Humans and most animals lack the enzyme essential to digest cellulose in their bodies.Many plants such as hay and grasses have cellulose in the abundance.Starch is easily digested as it is also a polysaccharide but is storage-based. Cows, ox, horses, and such animals can digest cellulose due to having bacteria in their gut that produce enzymes.

Thus, the correct answer is -  cellulose is a polysaccharide that is indigestible for most animals as they lack anaerobic bacteria that produce enzyme help in digestion of cellulose.

If a DNA strand lias a sequence GTA, what will be the tRNA anticodon sequence?
A. GUA
B. CAU
C. GTA
D. CAT​

Answers

Answer:

CAU

Explanation:

DNA is a nucleic acid that carries the genetic material. If the DNA sequence has GTA bases, then the tRNA anticodon sequence will have codon GUA. Thus, option A is correct.

What is the tRNA anticodon sequence?

tRNA anticodon sequence includes the three nucleotide bases complementary to the codons presented on the mRNA sequence.

The mRNA is complementary to the DNA template (GTA) and will have a sequence as "CAT." The tRNA has anticodons that, in turn, are complementary to the mRNA and will have a sequence of "GUA."

Therefore, GUA is the tRNA anticodon sequence.

1) Scientists cannot change a hypothesis before beginning their experiment.

2) A hypothesis must be testable to be valid.

3) The steps of the scientific method must be performed in order, or the test is not valid.

4) Conclusions must be based on data rather than beliefs.

Answers

1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?

2) False. A hypothesis can’t be “valid” because it’s literally a prediction.

3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS

4) True. The conclusion must be based on data because it’s the observation that was seen.

O A The number of small mammals would decrease, leading to an increase in food for plant eaters.
OB. The number of other small predators would decrease, leading to an overall increase in the food supply.

14. What is the purpose of doing multiple trials in an experiment?

Answers

Answer:

This question is incomplete as it lacks options, the options are:

A. To get as much data as possible.

B. To make sure the procedure is done correctly every time.

C. Eliminate observations that are not typical and reduce error

D. To double-check the results so they are the same each time

The answer is C.

Explanation:

An experiment is carried out to test a hypothesis, which is a predictive explanation/solution to a problem. The experiment aims at accepting or rejecting the hypothetical claim. However, the experiment needs to be conducted more than once, which is called MULTIPLE TRIAL.

An experiment is conducted multiple times in order to improve how accurate the results are. This means that the error in the experimental results is brought to minimal by replicating or doing it multiple times. Hence, the purpose of conducting an experiment in multiple trials is to eliminate observations that are not typical and reduce error
