A thermometer is placed in water in order to measure the water’s temperature. What would cause the liquid in the thermometer to drop?
The molecules in the water spread apart.
The molecules in the thermometer’s liquid spread apart.
The kinetic energy of the water molecules decreases.
The kinetic energy of the thermometer’s liquid molecules increases.
When the thermometer is placed in cooler water, the liquid inside the thermometer (usually mercury or alcohol) will contract or come closer together. This occurs because as the temperature of the water decreases, the kinetic energy of the water molecules decreases. hence option C is correct.
What is kinetic energy?Kinetic energy is a form of energy that an object possesses due to its motion. It is defined as the energy that an object has because of its motion, and its amount is proportional to the mass of the object and the square of its velocity.
A decrease in temperature would cause the liquid in the thermometer to drop. The reason for this drop is that the molecules in the thermometer's liquid would contract or come closer together due to a decrease in kinetic energy.
The thermometer's liquid molecules would lose kinetic energy as they come into contact with the cooler water molecules, which would result in a decrease in the volume of the thermometer's liquid. This decrease in volume would cause the liquid in the thermometer to drop.
As the water molecules come into contact with the thermometer's liquid, the kinetic energy of the thermometer's liquid molecules is transferred to the water molecules, causing them to slow down and contract.

1.Suppose there is a drought and play and plant cannot get enough water. What happens to the cytoplasm of and the organelles in the plant cells?
2. describe the main differences between lysosomes and vacuoles
3. Could a single part of a multicellular organism survive on its own? Explain your answer
Answer:
1: if they cannot get enough water they will use techniques to protect themselves and conserve water.
2: Vacuole is a cell organelle which contains mainly water while lysosomes also cell organelle and are regarded as suicid bags by function. Vacuoles stores the undigested nutrients while the Lysosomes are the membrane bound sacs containing digestive enzymes that breaks down large molecules.
3: No, a single cell can carry out its functions independently but cannot survive or be sustained on its own because it needs help from the other cells from the multicellular organism to function properly.

How does the design of an experiment relate to the method of difference
The design of an experiment is synergistically related to the method of difference. Both are required in order to test a hypothesis and deliver a conclusion or evidence.
What is an Experimental design?An experimental design may be defined as the procedure of accomplishing research in an objective and regulated fashion so that accuracy is maximized and specific conclusions can be haggard regarding a hypothetic statement.
An experimental method may be defined as a methodology that is significantly executed in order to draw evidence or conclusion based on the hypothesis.
Both experimental plan and experimental method are required in order to withdraw specific conclusions about an experiment. In the absence of either factor, it is tough to deliver scientific evidence.
Therefore, the design of an experiment is synergistically related to the method of difference. Both are required in order to test a hypothesis and deliver a conclusion or evidence.
