Answer:
Independent variable: DIFFERENT LENGTHS OF STRETCHING
Dependent variable: DISTANCE RUBBER BAND FLIES
Hypothesis: IF a rubber band is stretched longer, THEN the distance it flies will increase
Explanation:
The hypothesis of an experiment is a testable explanation or suggested solution to an observed problem or asked question. In this experiment, the hypothesis can be: IF a rubber band is stretched longer, THEN the distance it flies will increase
Note that, this hypothesis can be tested to be true/untrue
Independent variable is the variable that the experimenter manipulates or changes in order to bring about a response. The independent variable in this question is DIFFERENT LENGTHS OF STRETCHING THE BAND.
Dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, the measured/dependent variable is the DISTANCE RUBBER BAND FLIES

Which statement describes the law of superposition?
Sedimentary rocks were originally in horizontal layers.
In horizontal rock layers, each layer is younger than the one below it.
Rock layers must be in existence before something can happen to them.
Rocks that are not in horizontal layers were shifted by some geologic event.
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.
Therefore, Sedimentary rocks were originally in horizontal layers best describe law of superposition.

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:
C.the fertile offspring of individuals that are well adapted to their environment will make up the greater proportions of the next generation.
H.individuals better suited to their environment are more likely to survive and reproduce.
Explanation:
The requirements for evolution by natural selection are;
C.the fertile offspring of individuals that are well adapted to their environment will make up the greater proportions of the next generation.
H.individuals better suited to their environment are more likely to survive and reproduce because
Natural selection refers to basic mechanism of evolution where by organisms develop traits or characters that will make them to adapt, survive and reproduce in their environments thereby transferring those traits or characters to their next generations.
It is survival and reproductive mechanism.

Explanation:
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.

What is the best example of a cyclic event?
a. the appearance of Halley’s comet every 76 years
b. a hurricane moving up the east coast an hitting Long Island
c. an earthquake near Washington DC
d. a tsunami striking the east coast of Japan
The correct answer is A. The appearance of Halley’s comet every 76 years.
Explanation:
Cyclic events follow a pattern of occurrence, this means they occur every certain time and can be predicted. This category includes natural phenomena such as weather patterns or the phases of the moon. In this context, the one that is an example of a cyclic event is Halley's comet (option A) because the appearance of this comet occurs every certain time (76 years) and this can be predicted, which are two key features of cyclic events. Also, others such as hurricanes, tsunamis, or earthquakes do not follow a precise cycle or cannot be precisely predicted.

Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you feel awake and alert. Scenario B: Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. Which article is more likely to have been peer reviewed? How do you know?
Answer:
The article read by Yuki
Explanation:
The article read by Yuki is more likely to have been peer-reviewed out of the two articles illustrated in the scenarios.
This is because magazine articles are usually written by staff writers or freelance journalists as opposed to professionals that are responsible for writing professional journals. Moreover, magazine articles are intended for general public reading and as such, are written in general, non-technical languages while professional articles are written in technical languages intended for scholarly use.
Articles in magazines are usually unstructured and hardly report scientific results unlike those in professional journals that require well-structured formats.
Consequently, articles in the Professional Journal of Medicine read by Yuki is more likely to be peer-reviewed than the article read by Carmen in Tasty Food magazine.
Answer:
sample response:The article that Cicely read (Scenario B) has been peer reviewed. This article is published in a scientific journal and has been judged for quality by other professionals in the field.

a. ATP production during aerobic respiration
b. Light absorption during photosynthesis
C. ATP production during anaerobic respiration
O d. The breakdown of starch during digestion
Answer:
a
Explanation:
plants uses oxygen for respiration, so in that process respiration takes place and respiration in plants has to do with the conversion of oxygen to carbon dioxide which serves as a means of respiration and during respiration ATP is being produced which stands for Adeosine triphosphate

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.
