Pauline took two small identical containers and filled them with the same amount of water.She dissolved a tablespoon of salt in one of them and placed both containers in a freezer.Pauline then observed them every five minutes until one of them had frozen.What is most likely the dependent variable (outcome variable) in this experiment?
A.The time it took for the liquids to freeze
B.The amount of water in each container
C.The amount of salt in each container
D.The type of liquid
Answer:
A
Explanation:
This line should explain it "Pauline then observed them every five minutes until one of them had frozen."
The most likely dependent variable (outcome variable) in this experiment is the time it took for the liquids to freeze. The correct option is A.
What are the variables of the experiment?The variables of an experiment are the factors of the object on whom the experiment is done or the factors which affect the experiment. There are three types of variables. These are dependent, independent, and control variables.
Independent variables are those which can not be controlled by the person who is doing the experiment. The dependent variables can be changed or controlled by the experimenter.
A controlled scientific experiment will be controlled by the scientist, and it is to be checked that what time and what face of the experiment is going on.
Therefore, the correct option is A. The time it took for the liquids to freeze.

Answer:
Vertebrate:spine Invertebrate:no spine
Explanation:
Answer:
Invertebrates are animals that do not have backbones. 95%-97% of the members of the animal kingdom are invertebrates such as sponges, jellyfishes, squids, and roundworms.
Vertebrates, on the other hand, are animals with a backbone or a vertebral column and are composed of six groups: mammals, birds, reptiles, amphibians, and fishes. Humans are members of the vertebrates family too but are sometimes exempted from the list when the discussion leans towards animals.

Why do silver and copper have similar properties?
State your claim. Make sure your claim fully explains how two different materials can have similar properties.
Summarize the evidence you have gathered to support your claim and explain your reasoning. Type your response below and click submit in Schoology.
Answer:
These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive (by volume) of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive.
Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver is used widely in mission-critical applications as electrical contacts, and is also used in photography (because silver nitrate reverts to metal on exposure to light), agriculture, medicine, audiophile and scientific applications.
Gold, silver, and copper are quite soft metals and so are easily damaged in daily use as coins. Precious metal may also be easily abraded and worn away through use. In their numismatic functions these metals must be alloyed with other metals to afford coins greater durability. The alloying with other metals makes the resulting coins harder, less likely to become deformed and more resistant to wear.

What process of DNA is represented in the diagram below?
Answer:
DNA Replication
Explanation:
Because DNA's two strands are complementary, it can reproduce itself. This means that one strand can serve as a template for the creation of the other. It occurs just prior to cell division via mitosis or meiosis, allowing each new daughter cell to have a full genome.
The two strands of DNA must first separate from one another before replication can begin. DNA helicase is an enzyme that breaks the hydrogen bonds that hold the two strands together, allowing them to separate.

If an organism has more specialized cells, its cells ________
A. can survive on their own
B. have their own function
C. are all the same
D. do not have any function
Answer: B. Have their own function
Explanation:
Cells that perform a specific function in an organism are specialized. I also had the K12 test.
If an organism has more specialized cells, its cells B. have their own function.
Specialized cells are the cells that makeup tissues and make up the system that work together in our bodies.
Some examples of specialized cells that we've in our body include blood cells, nerve cells, and the reproductive cells. It should be noted that specialized cells have their own specific functions.
Therefore, when an organism has more specialized cells, its cells have their own function.

what is the role of a receptor in helping an organism maintain homeostasis
The role of a receptor in helping an organism maintain homeostasis is to detect stimuli and sends information to the control center. Thus, option C is correct.
What is homeostasis ?
Any self-regulating mechanism by which biological systems have a tendency to retain stability while responding to environmental factors that are best for survival.
The body's homeostasis keeps all cell processes and enzyme activity at their ideal levels. Despite changes in internal and external conditions, it is the maintenance of a constant internal environment.
As an instance of homeostasis in a biological system, the regulation of body temperature in humans is a good example.
Therefore, the control center receives input from the sensory receptor or sensor. Option C is correct.
