Which property of argon makes it useful for potassium-argon dating?
It decays into potassium.
It is an unstable element.
It remains trapped in rock.
It is useful only for dating newer rock.
Answer:
The correct answer is c, plz give me brainlest
Explanation:
got 100 percent on the quiz
A property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.
What is Radioactive dating?Radioactive dating may be defined as a type of methodology for dating rocks and minerals with the help of radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.
Potassium-argon dating is a method of determining the time of origin of rocks by estimating the ratio of radioactive argon in order to radioactive potassium in the rock. This dating method is typically based on the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks.
Therefore, a property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

Describe one physical property and one chemical property of sodium that ywe observed
Answer:
It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

You never have to worry about wastewater becoming contaminated because it can run through local treatment plants, true or false?
A person still have to be worried about wastewater becoming contaminated even though it passes through local treatment plants.
Wastewater refers to the water they has been used. It consists of the substances like human waste, oils, chemicals , food scraps etc.
Even though used water runs through local treatment plants, it should be noted that not all the solid waste are removed as some of the waste will still end up getting into nearby rivers or streams and this can result in contamination when one eventually uses such water.
In conclusion, one still has to be worried even though the wastewater runs through local treatment plants. Therefore, the correct option is False.

Buffers are substances that help resist shifts in pH by (From the close reading exercises)
A. releasing H+ to a solution when acids are added.
B. donating H+ to a solution when bases are added.
C. accepting H+ from a solution when acids are added.
D. both donating H+ and accepting H+.
Answer:
Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).
Explanation:
A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.
The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.
The other options are not correct because:
A. Buffers do not release H+ into a solution when acids are added, but accept them.
B and C. Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

D) They are the largest trophic level.
E) This level of the food chain has the highest

They attract secondary consumers, this applies to the tertiary consumers of the ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are interconnected through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into the plant tissue.
The term "ecosystem" was first used in 1935 in a publication by British environmentalist Arthur Tansley. The term was coined by Arthur Roy Clapham, who coined the word at Tansley's request.
The main ecosystem types are forest, desert, rainforest, grassland, tundra, savanna, and mountain ecosystems.

Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane
Answer:
D
Explanation:
D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.
Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.
The statement that best describes the permeability of a membrane is:
Option D. The ability to allow materials to cross a membrane.
This can be explained as:
Permeability is a physical property of membranes and substances that allows the other molecules to move through them.It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.Therefore, permeability is the allowance of materials across the membrane.

Blood isn't the only natural system that uses acid/base buffers. Limestone is made of calcium carbonate. How would you expect the pH of a lake with limestone bedrock to compare to other lakes after several years of acid rain?
how would you relate force and acceleration?
Force = mass * acceleration
This is Newton's second law
Explanation:
Hey there!
The external agency that brings change in body's action(i.e changes the body from rest to motion or motion to rest) is called a force.
We know;
The force is inversely proportional to acceleration. So, the best method to relate them is force in inversely proportional to acceleration of a place.

Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer

Answer:
Ok:
Explanation:
The woman eats and digests food to get glucose while the plant can undergo photosynthesis which forms glucose.
The plant and the woman utilize different mechanisms for accumulating glucose in their body to use for energy.
What is Glucose?Glucose may be defined as the main type of sugar in the blood which provides immediate energy to the body's tissues to perform metabolic activities.
Plants utilize the process of photosynthesis to construct their food
(glucose) with the help of carbon dioxide and water in the presence of sunlight, while the woman eats food products which are then digested into the stomach, and glucose is synthesized which is then transported into the bloodstream.
