This question is incomplete because the options are missing; here is the complete question:
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the
A. Solute
B. Acid
C. Solvent
D. Base
The correct answer to this question is Solute
Explanation:
Amanda's experiment involves adding a solid (salt) into a liquid and then mixing both to form a mixture categorized as a solution because one substance has disintegrated in another. Moreover, in this mixture, the liquid is considered as the solvent because this dissolves or disintegrates the salt and the salt is considered as the solute (substance dissolved). In this context, the liquid dissolved the salt or solute in Amanda's solution or mixture.

Choose all the true statements about oxidative phosphorylation.
A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.
B. The oxidation of NADH provides enough energy to produce three ATP molecules.
C. Oxidative phosphorylation is an anaerobic process.
D. The oxidation of FADH, provides enough energy to produce three ATP molecules.
E. Oxidative phosphorylation and the electron transport chain are called coupled reactions.
Answer:
A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.
B. The oxidation of NADH provides enough energy to produce three ATP molecules.
Explanation:
Oxidative phosphorylation is the third step of cellular respiration, in which NADH2 or FADH electron carriers are oxidized to produce ATP. Oxidative phosphorylation occurs in the inner mitochondrial membrane. It is composed of two processes viz: electron transport chain and chemiosmosis.
Either NADH2 or FADH is used as the starting electron carrier. When NADH is used, its oxidation produces enough energy to generate 3 molecules of ATP per molecule while FADH generates 2 ATP molecules.

Birds and humans are theorized to have a common ancestor because they have homologous structures. Which evidence best supports this theory? They both have tails and embryos. They each have vestigial structures. They have analogous structures. They have different forms as adults.
Answer:
They each have vestigial structures.
Explanation:
Birds and humans have a common ancestor as they have homologous structures.
Vestigial structures are the organs that have some important functions in the past but now in present, they do not perform any function.
Both humans and birds have vestigial structures such as humans have an appendix and ear pinna and wings of flightless birds such as ostrich.
Hence, the correct answer is "They each have vestigial structures.".
Answer:
They each have vestigial structures.

Which describes the paleoanthropology practice of walking the landscape looking for fossils on the surface?
Answer:
The correct answer is : surveying.
Explanation:
Paleo-anthropology is the study of the extinct primates, it is a sub branch of anthropology. It is focused on the human evolution and rise of the sub type of family of the other human or hominids.
Surveying is the one of paleoanthropoolgy practices that involves the finding the fossils of hominids on the surface of all around the globe by walking to compare it and study the evolution of human family.
Thus, the correct answer is- surveying.

Explain what the interviewer meant when he said that genetic mutations are like misprints in a book.
Answer:At times parts of the gene can change entirely, leading to alteration of the product. There are many types of gene mutations, but all types of mutation can potentially affect the cell and its function.
Explanation: A publisher can misprint a book in several ways. The publisher can miss words, make spelling erros, mix up paragraphs or delete some text entirely.With these kinds of errors, the text will be inaccurate, and the reader can get confused. Mutations in genes happen similarly.

if a paper clip weighs 1.0 g how many paper clips would be in a paper clip box that weighs 0.5 kg
Answer:
500g
Explanation:
0.5kg=500g
500/1 = 500g
There are 500 paper clips in a paper clip box that weighs 0.5 kg.
What is a Paper clip?A paper clip may be defined as a type of material that is made up of steel or some other metal, but molded plastic is also used for binding up papers.
Weight of one paper clip = 1.0 g.
Number of grams in 0.5 kg = 500 g.
∴ Number of papers clips in 500 g = 500 × 1.0 = 500 paper clips.
Therefore, there are 500 paper clips in a paper clip box that weighs 0.5 kg.

Amoeba breathes through its ______is utilized during respiration to release energy.
Answer:
Amoebas "breathe" by allowing oxygen from their aquatic environments to diffuse through their cell membranes.
An amoeba is a unicellular organism.
The statement that an amoeba is a unicellular organism, is True.
What is an amoeba ?An amoeba is a unicellular organism, which means that it is a single-celled organism. They are a type of protist, which are a diverse group of eukaryotic organisms that are not animals, plants, or fungi.
Amoebae are found in moist environments, such as soil, freshwater, and saltwater. They are able to move around by extending their cell membrane and cytoplasm, a process called pseudopodia. They use pseudopodia to capture food and to move to new locations.

What is the relationship between enzyme activity and 3D shape of an enzyme? What type
of environment changes affect the function of an enzyme?
Answer:
The reaction catalyzed by an enzyme is very specific. Most enzymes are proteins with unique three-dimensional configurations based on their amino acid sequence. The specificity of an enzyme can be attributed to the compatibility between the shape of the enzyme's active site and the shape of the substrate.

How does leaf structure best represent the relationship between structure and function? It indicates the maximum height an organism can reach. It determines how a plant responds to changes in the length of the day. It can be used to determine the average lifespan of the plant. *It relates directly to the characteristics of the plant's environment*
Answer:
The correct answer is - *It relates directly to the characteristics of the plant's environment*
Explanation:
The relationship between structure and function can be represented by the leaf structure as the structure of a particular plant leaf gives an idea about the characteristics of the environment it is habituated.
In the dry area or deserted area, leaves are modified into spikes to save water in order to lower transpiration, number of waxy coating, number of chlorophyll, and other modifications that give an idea about the environment and light intensity, and other characteristics.

Answer:
the answer is b (horizontal rock layers, each layer is younger than the one below it)
Explanation:
in rock layers, the top layer of a rock will be the newest, or youngest. and the very first layer at the bottom will be the oldest layer since the layers build on top of each other, hope that helps :)
Sedimentary rocks were originally in horizontal layers best describe law of superposition.
What is law of superposition?The law of superposition is a principle that guide stratigraphy stating which state that within a sequence of layers of sedimentary rock, the oldest layer is normally found at the base and that the layers continue to become younger with ascending order in the sequence.
