Why is water called the universal solvent?
A.) Water is a nonpolar substance that dissolves polar substances
B.) Water can act as a solvent in many different solutions
C.) Water is a polar substance that dissolves nonpolar substances
D.) Water can act as a solute in many different solutions
Answer:
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.
Explanation:
B.) Water can act as a solvent in many different solutions.
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees.Therefore, option B. is correct.

Which graph represents selection that may lead to reduced variation in a population? A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed. A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points. Mark this and return

A company manufactures a chemical which acts as a strong chemical solvent. The chemical has a negative impact on the environment and human health when non properly disposed of. In order to be in compliance with the cradle to grave' tracking expectations of the federal government, the company must most clearly understand and abide by which law to track the manufacture and disposal of this chemical? A) Clean Air Act B) Clean Water Act Safe Drinking Water Act D) Resource Conservation and Recovery Act
Answer:
D) Resource Conservation and Recovery Act
Explanation:
The Resource Conservation and Recovery Act of 1976 was passed to ensure that the processes involved from the generation to the disposal of hazardous wastes are properly managed and meet up to health and environmental standards. The cradle represents the generation of the wastes while the grave represents the disposal of the wastes.
The company generating the hazardous waste is also responsible for other processes such as the transportation, treatment and storage of the waste.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
a force has direction and contact true or false
Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.
Therefore, yes

Which type of weathering is the result of water freezing and expanding inside the cracks of rocks when it freezes?
a.biological weathering
b.chemical weathering
c. frost wedging
d. deposition
Answer:
C. frost wedging
Explanation:
Frost wedging is the process by which water seeps into cracks in a rock, expands on freezing, and thus enlarges the cracks. So, therefore, the answer must be C.
Describe the structure of a virus.
Answer:
All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.

Which has the larger ratio of surface area to volume, a tennis ball or a soccer ball?
Answer: Soccer Ball
Explanation: Because it is bigger and could hold more air.
The answer is Soccer Ball. Just because it is bigger and could hold more air.
What is the ratio of the surface location to extent limits?The ratio of surface place to an extent limits the dimensions of the cell textbf{the size of the cell} the dimensions of the mobile. This is due to the fact that the quantity of mobile will increase swiftly, the mobile's floor region decreases, to the factor that the ratio of floor place to an extent is a small price.
The surface vicinity to extent ratio is important for cellular diffusion in addition to cell department. So that you can live, cells require nutrients and oxygen to skip into the cell via its cell membrane, and they require waste to go away from the cells within the contrary course.

Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

Explain the difference between the effects of balanced and unbalanced forces on an object. To receive full credit you must mention net force and whether the motion will change or not.
Answer:
Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the change the object's motion.The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force
