Answer:
YELLOW
Explanation:
Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.
The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).
Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).
If a solution is undergoing a reaction where CO2 is being created a product, the phenol red-containing solution will be shifting toward the yellow color.
An indicator is an organic dye that changes its color as the pH of the solution changes. An indicator has a different color in acid, base and neutral media.
Phenol red has a yellow color in acidic medium and red color in a basic medium.
Since the production of CO2 lowers the pH of the system, the color of the solution shifts towards yellow.

Which motion of particles across a membrane requires energy?
O from high concentration to low concentration
from low concentration to high concentration
with no concentration gradient
O through dynamic equilibrium
Answers
Answer:
B. From low concentration to high concentration
Explanation:
I got it right on edge :)
Answer:
B
Explanation:
You can think of it as a very useless sponge and water.
If you have a dry sponge you can consider this an area of low concentration, and the bucket of water as an area of high concentration of water.
It is easy to soak up water with a dry sponge with osmosis when the high concentration easily fills the low concentration sponge.
On the other hand, a soaked sponge will have a great time trying to soak up a bucket of water with an already wet sponge.
This is a crude example of differing high to low or low to high concentration.
Osmosis is limited to water particles, whereas diffusion is basically molecules.
Osmosis is the movement of water along the concentration gradient.
Active transport is the use of energy to move particles against the concentration gradient so it is active, it is attempting to enact homeostasis.
Passive transport is the movement of particles by diffusion without energy so it is just passive, not aggressive.
Diffusion is the movement of particles along the concentration gradient.

16.)Which of the following properties of water help to dissolve sugar?
A.) adhesion
B.) cohesion
C.) surface tension
D.)Universal Solvent
Answers
Answer:
D
Explanation:
The property of water that helps it to dissolve sugar is the universal solvent property.
Water has the inherent attribute to dissolve a wide variety of substances due to the arrangement of the atoms that make up water molecules. The molecules of water are made up of hydrogen and oxygen, with the latter being negatively charged while the former is positively charged.
The polar arrangement gives water the capacity to be able to dissociate ionic substances into their respective positive and negative ions and also allow water to dissolve more substances than any other solvent in the world.
The correct option is D.

B. The cell membrane has numerous functions, but its primary role is to keep organelles contained within the cell
C. The cell membrane has many functions, but its primary action is to act as a barrier to keep foreign substances from moving into the cell
D. The cell membrane's primary function is to move waste out of the cell
Answers
The correct answer as to which best describes the function of a cell membrane would be that the cell membrane has many functions, but its primary action is to regulate the movement of materials into and out of the cell. The correct option would be A.
The cell membrane primarily delimits the cell and act as an interface between the inner content of the cell and its surrounding.
The cell membrane is selectively permeable. Thus, it regulates the movement of materials between the cell's matrix and the surrounding.
Other functions of the cell membrane include:
By regulating the movement of materials in and out of the cell, the cell membrane ensures that the optimal range of concentration of substances is maintained within the cell. In other words, it maintains homeostasis.By surrounding the cell, the plasma membrane becomes the first line of contact for anything that might want to harm the cell. Hence, it serves protective functions.By selectively allowing and influencing some materials to move out or inside the cell, the cell membrane plays an integral role in the transportation of materials.

B. Different blood types have different antigens that will be attacked by someone with antibodies against that blood type.
C. They need to have the same blood type because their DNA must be similar enough to blend or will cause side-effects and possibly be rejected.
D. Your blood type doesn't matter as long as you get the correct amount of blood in a transfusion.
Answers
Answer:
A and B
Explanation:
Doctors need to check the blood type of a person before administering blood transfusion because different blood types have different antibodies that will be attacked by someone with antigens against that blood type.
The blood that would be given to a person must match the blood of that person in terms of the type of antigens. If the blood antigens are different, the antigens present in the blood of the individual undergoing blood transfusion would consider the antigens present in the blood being received as an enemy and attack it. This will lead to agglutination of the blood in the system of the person, a process that often leads to death.
Hence, O-positive individuals must always receive O-positive blood while O-negative individuals must always receive O-negative blood.
The correct options are A and B.

For the following questions, please fill in the blank with the correct number of chromosomes (e.g. 4). Please do not spell out the number (e.g. four) or include any kind of punctuation (e.g. 4.). In an organism where the diploid number of chromosomes is 2N=16, how many chromosomes would you expect to find in cells that are in G2 of the cell cycle?
Answers
Answer:
Double number of chromosome.
Explanation:
There are 16 chromosomes in G2 phase of the cell cycle because in G2 phase, the replication of DNA occurs which doubles the number of chromosome. It is a gap phase present between replication of DNA and mitosis so it contains 16 number of chromosomes in the cell. After mitosis, the chromosomes number distributed equally among daughter cells.
