Which of the following is an example of a physical variable of water quality *
Answer: Physical properties of water quality include temperature and turbidity. While chemical characteristics involve parameters such as pH and dissolved oxygen. These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.
I hope this is the answer if not I apologize :P
Answer:
One of the physical variables that affect the properties of water is temperature
Explanation:
I assume that by physical properties you mean external factors that affect the properties of the water correct? well depending on the temperature of the air that the water is exposed to the war can shift from either a liquid to a solid if it if the air is cold or it can change from a liquid to a gas when the air is hot. I'll explain how this works when the temperature of the air is hot the water will under go an exo thermic reaction (A reaction that causes things to emit heat and become hot) and because water boils at a certain point as the water gets hotter and hotter it will evaporate into mist. If the air around the water is cold then it produces an endothermic reaction which will cause the ice to get colder and colder as time goes on until it transitions from being a liquid to a solid in the form of ice. Hope this helps:)

Explanation:
The classification of resources as renewable or nonrenewable is given.
Coal: nonrenewableGeothermal energy: renewableWind: renewableNatural gas: nonrenewableWhat are renewable and non-renewable resources?Energy sources that are renewable are those that can be utilized repeatedly and replenish themselves quickly. It is widely understood to refer to the kind of renewable energy sources.
Renewable energy sources can take the place of conventional energy sources that emit toxic gases and are both expensive and destructive.
Non-renewable resources are ones that can only be used once before having to be produced again over an extended period of time.
Burning fossil fuels harms our environment, and non-renewable energy sources are likewise bad for the environment.
Therefore, the correct option is

many cellular functions can be compared with functions that occur in organisms. which is not a function that both cell and an organism share. A stores waste material for removal B provides structure and support C learn behaviors that aid in survival D conversion of nutrients into usable energy
Answer:
learn behaviors that aid in survival
Explanation:
learn behaviors that aid in survival is not a function that both a cell and organism share because a cell is a basic unit of life and contains some organelles that perform little functions while an organism comprises of many specialised cells that work to perform similar functions. An organism have central nervous system which comprises of brain and spinal cord. Organisms learn new behavior and acquire cognitive skills through the brain development. The brain and spinal cord receive electrical impulses sent from neurons and interpret it to meaningful information.
Learning behaviors that aid in survival is not a function that both cell and an organism share.
LEVEL OF ORGANIZATION:The cell is the basic and functional unit of living organisms. This means that the cell harbors the functional characteristics of living organism.

Why do fish and frogs lay eggs in hundreds whereas a hen lays only one egg at a time?
Answer:
bc there eggs are tinnier then a hens egg
Explanation:
Answer:
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.

Plant and animal cells have many organelles in common such as the cell membrane. However, the function of the cell membrane differs between the plant and the animal cell. Which best describes how the function of the cell membrane differs in plant and animal cells?
A. In animal cells, the cell membrane is the outermost layer of the cell, while in plant cells, the cell membrane separates the cell wall from everything inside the cell.
B. In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell.
C. In animal cells, the cell membrane controls what comes in and out of the cell, while in plant cells, the cell membrane houses all the genetic material.
D. In plant cells, the cell membrane is made of a gel-like material that is green, while in animal cells, the cell membrane is made of a gel-like material that is red.
In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell. Thus option B is correct.
What are the function of plant cell wall ?
Plant Cell wall is composed of cellulose which is a sugar which is a rigid structure that provides support and protection to the plant cell from any external damage.
Mechanical strength can be provided due to the presence of skeletal framework in cellulosic microfibrils.
The various shapes of plant cell due to cell wall, the additional wall component include pectin and/or lignin
Growth of plant cell can also depends on the elastic and plastic nature of cell walls.
The transport of intracellular substances between plant cells can be done by cell wall.
It occurs in two ways such as apoplastic and symplastic transport.
