Notice the progression of the green and blue dots over time. What statements below describe what is happening
Answers
Answer:
The blue and green molecules are small and polar and can diffuse through the lipid bilayer
Explanation:
The plasma membrane is made up of a double layer of phospholipids. This arrangement permits the movement of small polar molecules by diffusion. However, larger molecules or ions need to pass through membrane channels or be carried over by active transport.

Large predatory birds, such as hawks and eagles, feed on small mammals, fish, and other birds. Some predatory bird species came close to
extinction in the mid-1900s because of the pesticide DDT.
What would most likely happen to the number of other organisms if many of the large predatory birds were removed from an ecosystem?
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.
O c The number of small mammals would increase, and they would eat many of the plants that other species need.
OD. The number of large plant eaters would increase, and they would eat many of the plants that small animals need.

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.

The results of the experiment MOST STRONGLY
support which conclusion about the polarity of
lipid molecules?
Lipid molecules are polar because they mix poorly
with liquids, such as water.
Lipid molecules are polar because they adhere
tightly to smooth surfaces, such as paper.
Lipid molecules are nonpolar because they repel
water molecules, which also are nonpolar.
Lipid molecules are nonpolar because they repel
water molecules, which are polar.
Answers
Answer:
lipid molecules are non polar because they repel water molecules, which are polar
Explanation:
A lipid is an organic compound that is insoluble in water. A lipid consists of hormones, waxes, oils, fats. Also, a lipid is a form of chemical messengers and energy-storage molecules. Lipids are basically insoluble bio molecules.
The results of the experiment MOST STRONGLY support the following statement.
''lipid molecules are non polar because they repel water molecules, which are polar''

Laurie and Abby decide to make guacamole dip with chips to bring to a party. Laurie used a type of avocado called a Hass Avocado and Abby used a type of avocado called a Fuerte Avocado. Laurie and Abby both made their guacamole dip the same way except for one thing...Abby put lemon juice in hers to give it a 'tang.' When the girls uncovered their dip at the celebration, Laurie's had turned a brownish green but Abby's was still bright green. The girls wondered if adding the lemon juice to Abby's guacamole dip had helped it stay a nice bright green.
Hypothesis:
What is another variable that Laurie and Abby could test in this situation in a 2nd experiment?
Answers
Answer:
Lemon juice has 'chemicals' in it that make it citrus, and those same 'chemicals' preserve the guacamole. same thing as the 'life hack' where you rum lemon on cut apple slices and it makes them not brown.

A scientist is unsure about the accuracy of her experiment. She has checked her equipment and found it to be in good working order, checked her data and found it to be accurate, and reviewed her interpretation of the data, which she found to be logical. What should she do in addition to check the accuracy of her results?
Answers
Answer:
The answer to the question above is given below
Explanation:
Since the scientist is unsure about the accuracy of her experiment, it could be possible the procedure she used was reliable but the result inaccurate or the procedure can also be inaccurate and also the result. She checked her equipment, data, and even the interpretation of the data and found all to be correct. But it wasn't mentioned if she repeated the experiment.
The following points will briefly highlight other possible ways to further check the accuracy of her results:
1. The accuracy of an experiment could also question how reliable it is. She should repeat the experiment over and over again without changing any parameter she used initially to test if she gets the same result. Similar results would imply an accurate experiment.
2. She should check if an experiment has been done before by another scientist on the same subject, check parameters used and compare values and results. This in other words is checking if the hypothesis is true.
3. She should check for random errors that could arise from environmental conditions that could influence her final result.
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.

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

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.
