The role of the cell membrane is most like the job of which person?
Answer:
The officer that allows people in and out of the crime scene.
Explanation:
The cell membrane chooses what comes in and out of the cell, therefore the officer would be most similar to the job of the cell membrane.
Answer:
It has a job similar to a police officer who allows select people to enter and leave a crime scene.
Explanation:
The primary purpose of the cell membrane is to preserve the cell from its surroundings. The cell membrane manages the movement of materials in and out of cells and organelles. In this form, it is selectively perforable to ions and organic molecules. It is the same as of police officer or security guard that check the people and allow only a few to enter a specific place.

Describe how the skin cells, neurons, muscle cells, and blood cells you have observed relate to the functions of skin, nerve, muscle, and blood tissue.
Answer:
The form makes the function, this saying is named by many scientists, and they were the ones who made a relationship with the physiology of the organ or tissue and the shape of the cells that make it up.
Explanation:
In the case of neurons, they have extensions to spread and transmit signals, epithelial cells form many layers and have the ability to shed, that is why their main function is the body's innate protective barrier.
Red blood cells are double-headed and enucleated, to be made up of proteins that conform to oxygenation and thus diffuse oxygen well throughout the body.
And finally the muscle cells, which are tapered, with internal sarcomeros, similar to an elastic, to be able to carry out effective contractions starting from a certain length.

Answer:
D. it would produce smaller amounts of more concentrated urine
Explanation:
In salt water, the concentration of salt would be higher outside the cells than inside. Therefore, the concentration of water inside the cells is higher outside than in. Water leaves the skin and gills via osmosis, moving from a high concentration to a low concentration.
This means the urine is highly concentrated, and produced in small volumes (as most of the water has left via osmosis, not urination)

Is endocytosis a form of active
transport?
A. Yes, because molecules move down the
concentration gradient without using energy.
B. No, it is a form of diffusion.
C. Yes, because it requires energy to move a
molecule against a concentration gradient.
Answer:
A. Yes, because molecules move down the
concentration gradient without using energy.
Explanation:
Active transport is the energy-requiring process of pumping molecules and ions across membranes against a concentration gradient. Both endocytosis and exocytosis are active transport processes.
Hope that helps!

13) Identify the product of dark reaction.

Answer:
its C B A B
Explanation:
Photosynthesis is a series of metabolic reactions by which plants and algae use sunlight, water (H2O), and carbon dioxide (CO2) to produce molecular oxygen (O2) and energy in the form of carbohydrates (glucose).
Photosynthesis has two types of reactions:
The light-dependent reactions. These reactions convert light energy into chemical energy (ATP and NADPH).The light-independent reactions (dark reactions or Calvin Cycle). These reactions fix carbon from CO2 into molecules which are then used to produce sugar (glucose).The reactants in the light-dependent reaction include light and water (H2O).The products of the light-dependent reactions are ATP, oxygen and NADPH.The reactants in the dark reactions are ATP, NADPH and carbon dioxide (CO2).The product of the dark reactions is sugar (carbohydrates).In conclusion, photosynthesis has two types of reactions: light-dependent reactions and light-independent (Calvin Cycle) reactions.

A unknown element is a gas at room temperature, has 8 valence electrons and 22 neutrons the element is most likely
Answer:
Argon
Explanation:
Argon is a chemical element which is a gas at room temperature, has 8 valence electrons and 22 neutrons. This element belongs to the noble gas elements group.
What is Argon?Noble gas is any of the rare gases that include helium, neon, argon, krypton, xenon, and sometimes radon also and that exhibit great stability and extremely low reaction rates than other elements in the periodic table.
Argon is a chemical element with the symbol Ar and it has an atomic number of 18. It is in the group 18 of the periodic table and it is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.9340 ppmv. It is more than twice as abundant as that of water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon gas. Argon is the most abundant noble gas in the Earth's crust, which comprises about 0.00015% of the crust.

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
Kaya's antigens were attacking the tissue.
Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
O Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count.
Answer:
The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.
Explanation:
When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.
One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.
It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
Administering antibiotics should not raise lymphocyte levels. There is no evidence of antigen attack. Immunosuppressant drugs do not increase lymphocyte count.Foreign particles are caught in the....

Answer:
Osmosis across the membrane
Explanation:
The diagram shows the movement of water molecules from outside the cell to the inside of the cell. The concentration of water molecules is higher outside of the cell than inside the cell, meaning the water molecules are moving from a high concentration to a low concentration across the semi-permeable membrane, a process called osmosis.
Exocytosis is the movement of molecules from the inside of the cell to the outside via a vesicle. The vesicle fuses with the plasma membrane and the contained substances are released outside the cell.
Active transport is the movement of molecules against their concentration gradient and requires energy.
Facilitated diffusion is used by molecules that cannot freely cross the plasma membrane (e.g. large polar molecules and ions)

Osmosis across the membrane
