Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
Answer:
they will gather quantitative Data, using a thermometer and a balance.
Explanation:
This experiment is a type of quantitative research.
Quantitative Reseach:
Studies the effect of an independent variable on dependent variables by collection of quantifiable data that can be subjected to mathematical or statistical tools to draw conclusions.
The students will need a thermometer and balance to note the variation in the temperature of water in the aquarium and to measure the weight/mass of the duckweed respectively. Plotting these values against each other on a graph will give the effect of temperature on the rate of growth of the duckweed.
Binomial nomenclature is naming a organism by its genus and species the rules are the genus always comes first and the first letter is capitalized and the species always comes second and is lower case so the mountain lion would be Felis concolor
DNA gets compact only during cell division and are called chromosomes. On other conditons, it forms a network of thin threads called chromatin network.

Combining TCAs with warfarin creates a risk for bleeding,
which should be addressed in the nursing care plan. There is no known interaction
between TCAs and calcium supplements or bisphosphonates that would create a
risk for hypocalcemia. TCAs do not heighten the risk of gastroesophageal reflux.
TCAs can affect blood pressure, but this is unrelated to any known drug-drug interactions.
