4. How much confidence would you have in the conclusion of experiment 3 if you found out that the temperature was not
controlled? Explain your reasoning.
5. Create your own flow chart to answer a causal question.
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.The flow chart for the increase in pressure affecting the evaporation is given in the image attached.Read more about variables :

Explain how the circulatory system is able to transport the blood under high pressure from the heart to the rest of the body
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.Transporting blood under high pressure can be explained in the following steps:
Contraction of the heart ventricles creates blood under high pressureHigh pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elasticThe lumen of the arteries is narrow thus helping in maintaining high pressureAs a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

Arrange the following events in the order in which they occurred.
Answer:
1→4→5→3→2
∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.

Please only answer if you know
V-pattern caused by fire burning upward. Thus, the correct option is B.
What do V patterns in burn mean?V-Patterns: Because fire burns up in a V-shape, a fire that starts at an outlet next to a wall will leave a char pattern that will help identify the source. A fire that is hotter than usual, such as one aided by an accelerant, may have an extremely narrow V-shape.
The observable or quantifiable physical changes or recognisable shapes produced by a fire effect or combination of fire effects are known as fire patterns, sometimes known as burn patterns. The changes that occur in or on a substance as a result of exposure to fire are known as fire effects.

How does sucrose move in the sieve tube?
The sucrose move in the sieve tube by active transport.
What is active transport?Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells into sieve tube elements by active transport. This reduces the water potential of the sieve tube element by osmosis, which increases the hydrostatic pressure.

2. Insert one graham cracker section into the bowl. To create a ramp-like structure out of the Graham Cracker, place one end on the bowl's lip and the other end at the bottom. To secure the cracker to the side of the bowl, dab some icing on the back of the cracker.
3.Add water to the eyedropper. Hold the dropper at a height of about 1 inch above the cracker's top. the dropper over the cracker in the middle. Apply 100 drips, always aiming for the same area.
4.Keep an eye on what the cracker does. Keep a record of your findings.
5. Pour the water into a glass that is clear after removing the Graham cracker. Make notes about the water, grading its cloudiness among your observations.
6.In the same manner as in step 2, clean and dry the bowl and add a Graham cracker to it. Grab an ice cube and wipe it over the graham cracker until it melts completely.
