QUESTION 3
Coffee (pH 5) is how many times more acidic than baking soda (pH 9)?
a. 100,000x
b. 1,000x
c. 10,000x
d. 100%
Coffee (pH 5) is 10,000 times many times more acidic than baking soda (pH 9). The correct option is c.
What is pH?The pH of indicates how acidic or basic a compound is.
Every pH value less than 7 is ten times more acidic than the next higher value. A pH of 4 is ten times more acidic than a pH of 5, and a pH of 6 is 100 times (10 x 10) more acidic than a pH of 4, and so on.
In the given case, as coffee has pH 5 and baking soda is having pH 9 so it will have 10,000 times more acidic nature.
Thus, the correct option is c.

what is the indepent variable, dependent variable, and constants of the cell transport lab? here is the procedure: Procedure: 1. Before beginning the experiment, record at least two observations of the raw egg in your lab report. 2. Wrap the string around the center of the egg to determine its initial circumference. Measure the string and record the initial circumference in centimeters (cm). 3. Gently wrap the egg in the jar and completely cover the egg with vinegar. Use the lid to seal the jar and note the time. This will be considered the "start time" of the experiment. 4. After approximately 24 hours from the start time, carefully remove the egg from the jar of vinegar. If the shell has completely dissolved, exposing the inner membrane, move on to the next step. If not, return the egg to the vinegar until the shell has completely dissolved. 5. Record at least two observations of the egg. 6. Measure and record the circumference of the egg, being sure to measure it in the same way
Complete experiment:
Before beginning the experiment, record at least two observations of the raw egg in your lab report. Wrap the string around the center of the egg to determine its initial circumference. Measure the string and record the initial circumference in centimeters (cm). Gently place the egg in the jar and completely cover the egg with vinegar. Use the lid to seal the jar and note the time. This will be considered the "start time" of the experiment. After approximately 24 hours from the start time, carefully remove the egg from the jar of vinegar. If the shell has completely dissolved, exposing the inner membrane, move on to the next step. If not, return the egg to the vinegar until the shell has completely dissolved. Record at least two observations of the egg. Measure and record the circumference of the egg, being sure to measure it in the same way every time you measure circumference. Pour out the vinegar and rinse the jar. Then fill the jar about half full of tap water. Gently place the egg back into the jar, making sure it is completely covered with water. Use the lid to seal the jar. After a total of 48 hours from the start time, carefully remove the egg from the jar of water. Make two observations of the raw egg, and measure and record the circumference. Gently place the egg back into the jar, making sure it is completely covered with water. Use the lid to seal the jar. After a total of 72 hours from the start time, carefully remove the egg from the jar of water. Make two observations of the raw egg, and measure and record the circumference. Describe the results of your experiment or study. Use graphs and charts where appropriate.Answer and Explanation:
During an investigation, a researcher can study, under controlled conditions, how one of the variables influences the other one. The independent variable can be manipulated by the researcher, while the dependent one can not. The independent variable can show different values that do not depend on another variable. Instead, they directly affect the values of the dependents ones. A hypothesis is a claim of how this relationship works.
The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable / Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. This variable is modified during the experiment to analyze how another variable responds to it. The researcher wants to study how the changes in these variables affect the dependent variable. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. Usually, the independent variable is represented by the X letter. In the exposed example, the researcher manipulates the time that the egg is submerged in water. Time spent in the water is the independent variableDependent variable / Responding variable: Its response depends on any change in the independent variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. It is usually identified by the letter Y. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the egg circumference.The egg gets bigger changing its circumference as it spends more time submerged in water. The longer time it is submerged, the bigger it gets.
Constants / Controlled variables: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the use of the lid to seal the jar and the amount and concentration of vinegar might be considered as a controlled variable. These elements are used but do not provoke any change in the size of the egg.Answer:
• Independent Variable: time the egg spends in the water.
• Dependent Variable: The egg circumference
• Controlled Variable: Quantity of vinegar.

A fusion protein can be sythesized to carry a specific tag, which is useful in identifying the proteins in various experiments. Fusion proteins with the FLAG epitope bind to specific anti-FLAG antibodies and carry this extra sequence:
Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys
At a pH of 7.0 the amino acids that would be charged in FLAG are:______.
A. Tyr.
B. Lys.
C. Asp.
D. Glu.
Answer:
B and C
Explanation:
At a pH level of 7, aspartic acid has a net charge that is of -1, that is it is negatively charged.
While lysine has a net charge of +1 at this same pH level of 7
Tyrosine on the other had has zero net charge at this pH. And glutamine itself is absent.
Therefore the amino acids that are going to be charged are :-
b. Lys
c. Asp

Fresh milk has several parts that a farmer can separate and sell. A farmer removes the top layer of fat from fresh milk. What property does the farmer use to separate the fat from the rest of the milk?
A. density
B.Magnetism
C. Boiling Point
D. Electrical Conductivity
The fats present in the top layer of fresh milk can be separated from the rest of the milk by the help of density gradient. Thus, the correct option is A.
What is density gradient?Different molecules present in a cell or liquid can be separated on the basis of density gradient. Density gradient is the difference in the density of compounds. It is a spatial variation in density over an area in a compound or cell. It is used to describe the changes in the densities of matter. This is used widely in laboratory for the purpose of the separation of compounds such as DNA, RNA, proteins, cell organelles.
The fats present in milk does not mix well due to difference in their densities with the other parts of the milk. The fats in milk has a lower density than the other compounds present in the milk.
Therefore, the correct option is A.

A. would be a good item to add to the list of characteristics of life since there aren't any
non-living things that can do photosynthesis.
B. would be a good item to add to the list of characteristics of life because all life either
directly or indirectly gets its energy from the sun.
C. would not be a good item to add to the list of characteristics of life because not all
living organisms can conduct photosynthesis.
D. would not be a good item to add to the list of characteristics of life because someday in
the future, a non-living thing may be able to conduct photsynthesis.
E. Is currently one of the characteristics of life
Answer:
Is currently one of the characteristics of life
Explanation:
One major characteristic of life is nutrition. Nutrition refers to the process by which a living organism obtains its food.
Photosynthesis belongs to the kind of nutrition called autotrophic nutrition. Autotrophs are living organisms that produce their own food from simple inorganic chemicals.
Hence, only living organisms can undergo nutrition and it is already one of the characteristics of life.
