Note that the experiment you are performing is known as "Solar water distillation" experiment.
The water in the cup is probably unclean because the dirt and water combination in the bowl filtered through the plastic wrap and into the cup via evaporation and condensation.
The plastic wrap represents the Earth's atmosphere, while the water in the cup represents purified water collected, or "distilled," by evaporation and condensation.
The water in the bowl would have evaporated and condensed on the inside of the plastic wrap, running down and into the cup. Evaporation and condensation are the two components of the water cycle at an action in this research.
What is the purpose of the above experiment?The goal of the preceding experiment is to illustrate and comprehend the process of solar water distillation, which is a method of purifying water using the energy of the sun.
The experiment replicates the evaporation and condensation processes, in which the sun's heat causes the water in the bowl to evaporate and then condenses on the plastic wrap, pouring down into the cup.
The dirt and contaminants in the water are left in the bowl, resulting in clean water in the cup. The experiment aids in understanding the fundamental concepts of solar stills and how they may be used to purify water in isolated places or during survival scenarios where access to clean water is limited.

The circle below represents sells the arrow shows the movement of materials State whether each diagram represents active or passive transport
Passive transport carries molecules from the more concentrated side to the less concentrated one, while active transport carries molecules against their electrochemical gradient, needing the energy to do it.
Note: Since the image is not attached and I could not find it, I will define active and passive transport and attach an image with cells, molecules, and arrows indicating molecule motion for each transport case.
What are active and passive transport?Active and passive transport are two ways in which substances can move through the plasmatic membranes.
Passive transport occurs in favor of an electrochemical gradient and does not need energy to move because molecules move from the more concentrated side to the less concentrated one.
Simple diffusion and facilitated diffusion are two types of passive transport.
On the contrary, active transport moves molecules against their electrochemical gradient. This means that molecules move from the concentrated side to the more concentrated one. This process needs the energy to occur.
In the attached image you will find two scenarios. One of them is passive transport and the other one is active trasport. You should notice the differences in substances concentrations at each side of the membrane, and the arrow direction.

Do the tissues lining the gastrovascular cavity in Cnidarians differ at any point in the cavity?
All cnidarians have two tissue layers. The outer layer is called the epidermis, whereas the inner layer is called the gastrodermis and lines the digestive cavity. Between these two layers is a non-living, jelly-like mesoglea
Cnidarias have an internal sac for digestion which is called the gastrovascular cavity. The gastrovascular cavity has only one opening, a mouth, through which the animal takes in food and releases waste. Tentacles radiate outward from the rim of the mouth.
The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis. The epidermis contains a collection of different types of cells. These include epitheliomuscular cells which contract and enable movement, interstitial cells that give rise to many other cell types such as egg and sperm, cnidocytes which are specialized cells unique to cnidarians which in some cnidarians contain stinging structures, mucus-secreting cells which glandular cells that secrete mucus, and receptor and nerve cells which collect and transmit sensory information.
The inner layer, the endoderm , has cells that produce digestive enzymes and break up food particles. The jellylike material between the two layers is called the mesoglea. All of these body layers surround a central cavity called the gastrovascular cavity, which extends into the hollow tentacles.

Why is it important that a pure water IV not be given to dehydrated patients?
Pure water IV is not given to a dehydrating patient because our circulation already includes some salt, IVs also contain saline, a solution of water and salt that is almost isotonic with blood. Water flows from a high concentration to a low concentration, preventing the cells from exploding.
What would happen if you injected pure water into a patient?Patient would pass away. The cell would rupture owing to osmosis because of the disparity in salt content between the interior and exterior. In order to establish an isotonic state, the water would exit the cell and switch from the less concentrated inside to the more concentrated outside, killing the cell and ultimately the patient.
Hence, Continuous monitoring is necessary when receiving a saline water IV injection to make sure the IV solution is giving the patient the proper amount of fluids and minerals.

Preparation of the correct buffer is key to any good biological experiment and it is important that you understand how to calculate the mass of each chemical required to make that buffer and what the resulting concentration of those constituents will be in moles per litre. Your text book explains that moles are just a way to express the amount of a substance, such that one mole is equal to 6.02 x 1023 particles of that substance. These particles can be can be atoms, molecules, ions etc, so 1 mole of water is equal to 6.02 x 1023 water molecules, or 1 mole of Na+ is equal to 6.02 x 1023 Na+ ions. Since different chemicals have different molecular weights (based on the number of protons and neutrons each atom contains) 1 mole or 6.02 x 1023 atoms of oxygen (O) will have a mass of 16g whereas 1 mole or 6.02 x 1023 atoms of sodium (Na) will have a mass of 23g. If you need more information on moles, please read Encyclopedia Britannica's Moles website. Although you may sometimes see it written as g/litre, the concentration of solutions is more often described in term of molarity since it better defines the chemical properties of a solution because it is proportional to the number of molecules or ions in solution, irrespective of molecular mass of its constituents. However, it is not possible to measure moles on a laboratory balance, so in the first instance chemicals are measured by mass (milligrams, grams, kilograms etc) and the number of moles is calculated using the known molecular mass (often called molecular weight and abbreviated to M.W.) of the chemical. As indicated earlier, the molecular mass of a chemical is based on the number of protons and neutrons that is contained in each atom (eg NaCl is made up of one molecule of Na, M.W. = 22.99g and one molecule of Cl, M.W. = 35.45g, so the M.W. of NaCl is 58.44g). These values can be found in the periodic table however the molecular mass of chemicals is generally provided by any vendors of the products and so can also be found on various suppliers’ websites.
Molecular masses of the given sample are:
NaCl: 58.44 g/mole, 80 g, 1.37 M
KCl: 74.55 g/mole, 2 g, 27 mM
Na2HPO4: 142.01 g/mole, 14.2 g, 100 mM
KH2PO4: 136.09 g/mole, 2.4 g, 18 mM
What do you mean by molecular mass?The molecular mass is the mass of a given molecule: it is measured in daltons. Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.
Moreover, molecular mass or molecular weight is the mass of a molecule. “The molecular mass of a substance is the sum of the atomic masses of all the atoms in a molecule of the substance”. It is expressed in the atomic mass unit(u).
Therefore, molecular mass of an element is defined as the sum of the masses of the elements present in the molecule. Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule.

Which is not a way that ectothermic animals maintain their bodies at a consistent, appropriate temperature?
A. By generating large amounts of metabolic heat
B. By constricting or dilating blood vessels near the surface of the skin
C. Through behavioral adaptations such as basking in the sun or cooling in the shade
D. Bypassing cool venous blood near warm arteries running in the opposite direction
The method by which ectothermic animals do not regulate their body temperature is: (A) by generating large amount of metabolic heat.
Ectothermic animals such as snakes as well as lizards do not utilize metabolic heat in order to maintain their body temperature. Ectothermic animals are primarily dependent on the external sources of heat. The body temperature of such animals changes according to the external temperature.
On the other hand, endothermic animals tend to maintain a uniform body temperature through the process of metabolic heat production, e.g. birds as well as mammals. The internal body temperature of endothermic animals is almost independent of the temperature of their surrounding habitat.

The Atlantic puffin feeds on several species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed on the types of fish shown in the graph below. The beaks of this group of puffin are shaped to grasp Species A particularly well. Predict what would happen to the puffins’ beaks if another predator enters the area that is better at preying on Species A. Explain your reasoning based on what you know regarding genetic adaptations.
The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.
What is adaptation?
Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.
Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.
Hence, after many generations, puffins of species B and C will increase.
