Consider the two samples of sedimentary rock seen here.Predict which rock would be more likely to undergo physical weathering. Explain how and why.
A) Sandstone. Sandstone has more obvious layers of sediments.
B) Shale. Shale is fine grained and is more likely to dissolve in water.
C)Sandstone. Sandstone is made of large sand-like grains and is easily eroded by wind
D)Shale. Shale contains iron which is an element that easily combines with the oxygen in the atmosphere to produce rust.
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.
True or False: A hypothesis makes a prediction
Answer:
A hypothesis is a kind of guess or proposition regarding a situation. It can be called a kind of intelligent guess or prediction, and it needs to be proved using different methods. Formulating a hypothesis is an important step in experimental design, for it helps to predict things that might take place in the course of research. -or- What this statement means is that a hypothesis is a guess that a researcher in academia or other fields make and then follows an extensive research to either prove or disqualify the developed hypothesis as true or false. In contrary, a prediction is just but a guess that an individual makes without backing it with the necessary research in hope that it will happen.

A basketball player jumps straight up to dunk a basketball. The basketball player's speed increases as she returns to the
ground. What is true about the forces acting on the basketball player?
A. The upward force is greater than the downward force.
B. The downward force is greater than the upward force
C. The rightward force is greater than the leftward force.
D. The leftward force is greater than the rightward force.
Answer:
The downward force is greater than the upward force.
Explanation:
The remaining time is spent in the top of the jump (the top 25% of the jump). In other words, half the jump time is spent in the highest 25% of the jump (the top part of the arc). This explains why a basketball player appears to "hang" during the jump.

What is a SNP mutation?
Answer:
Explanation:
Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide.Most commonly, these variations are found in the DNA between genes.
single nucleotide polymorphism
A single nucleotide polymorphism, or SNP (pronounced "snip"), is a variation at a single position in a DNA sequence among individuals.
Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA. Most commonly, these variations are found in the DNA between genes.

The graph below shows the breakdown of a protein in the human stomach without a digestive enzyme.
Answer:
B
Explanation:
Take the test
The breakdown of protein in the presence of enzyme has lower activation energy.
The breakdown of protein in the stomach is achieved with the loss of peptide bonds, and the complex is broken down into amino acids.
What is breakdown of protein?The protein is broken down in the digestion at small intestine and stomach. The graph represents the energy of the reaction with the progress of protein degradation.
The energy of the reaction is highest when the protein breakdown activation is processed. The enzyme is the catalyst, that acts in fasting the reaction with the lowering of activation energy.
Thus, the breakdown of protein in the presence of enzyme has lower activation energy.

A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.
Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:
Answer:
a. independent variable: the fertilizer.
treatments: the use of fertilizer in one of the fields.
b. dependent variable: the crop growth in height.
units: meters
c. two controlled variables: soil pH / solar-radiation exposure, and water supply
d. hypothesis: the fertilizer makes the crops grow bigger.
e. two sources of error in the first year:
the researcher might plant the two crops under different conditionstake wrong measures of the height of the cornsf. two sources of error in the second year:
she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).Explanation:
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable. Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height. Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable. Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger. Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment, a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields. She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.What is the energy released from ATP used for?
