A laboratory assistant prepared solutions of 0.2 M, 0.4 M, 0.6 M, and 0.8 M sucrose but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. To determine the concentrations of each solution, the assistant filled four dialysis tubes with the four different solutions, took their initial masses, and placed each tube into distilled water overnight. The next day, the masses of each dialysis tube again were recorded. Using the data below, determine which concentration of sucrose solution is in each flask.
Answer:
To determine the flask on basis of the molarity or concentration of the solutions, an individual should design an experiment with the help of using water and dialysis tubes. Dialysis tubes up should be filled with pure water, then seal or closed them from both ends.
Measure the weight and note the mass of each tube, student should stick label the cups with the solutions. Weighing the solutions after leaving them for 8 to 10 hours. The tubes would lose weight as water leave the tube when placed in the solutions due to the principle of diffusion- movement.
The measure of the chemical constituents of the specific solute in a solution is called molar concentration.
For the determination of the flasks based on the molarity and concentration, the experiment should be designed based on dialysis tubes and water.
The dialysis tubes should be filled with pure water and both the ends of the tubes should be sealed.The tubes should be measured and marked. Place the tubes into the solutions and after leaving them overnight weigh them again.The weight of the tubes will decrease because of the flow of water.Therefore, due to diffusion movement, the tubes will lose weight and the concentration of the flasks can be determined.

What could create the need for a secondary succession?
i need the answer
Answer:
Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild.

What are the differences between the source of energy of producers and consumer
Answer:
Producers are capable of photosynthesis, a process by which they covert light energy into chemical energy, while consumers use respiration. Producers generate complex organic molecules, while consumers break them down into simpler ones (say, sugars to carbon dioxide, etc.).

Which of the following is released from ATP and therefore provides “energy”?
A) water
B) Pi
C) glucose
D) ADP and Pi
E) ADP only
Pi or inorganic phosphate is released from ATP and therefore provides energy.
What is ATP?It is the energy-carrying molecule found in the cells of all the living things. It is a nucleotide, which comprises three main parts, that is,
The nitrogenous baseAdenineRibose sugarA chain of three phosphate groups combined to riboseThe tail of phosphate is the actual source of energy, which is tapped by the cell. The accessible energy is present within the bonds between the phosphates and is discharged when the bonds are dissociated. It takes place via the supplementation of a water molecule, the process known as hydrolysis.
Generally, only the outer phosphate is withdrawn from the ATP to produce energy, when this takes place ATP get transformed to ADP or adenosine diphosphate.
Thus, the correct answer is option B, that is, Pi.

What did Oparin call the mixture of carbon-based molecules that would eventually from life ?
Answer:
Earth's primordial soup
Explanation:
Alexander Oparin was a Soviet biochemist who proposed theories for the origin of life through a book he called "The Origin of Life". He claimed that life on earth came about as a result of a gradual chemical evolution which is a mixture of carbon-based molecules that he called Earth's primordial soup (or sometimes called "organic soup").
Why is the series of reactions in the Calvin cycle called a
"cycle”?
Answer:
You can think of the Calvin cycle as being somewhat like a sugar factory within a chloroplast. It is called a cycle because, like the Krebs cycle in cellular respiration, the starting material is regenerated each time the process occurs. In this case, the starting material that gets regenerated is a compound called RuBP, a sugar with five carbons.
With each turn of the Calvin cycle, there are chemical inputs and outputs. The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle's output is an energy-rich sugar molecule. That sugar is not yet glucose, but a smaller sugar named G3P. The plant cell uses G3P as the raw material to make glucose and other organic molecules it needs.
Explanation:
You can follow the process of the Calvin cycle in the figure.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs.
The Calvin cycle simply refers to the process that algae and plants use in turning carbon dioxide into sugar. The Carbon cycle is made up of steps such as Carbon fixation, reduction phase, carbohydrates formation, and the regeneration phase.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs. The input molecules are ATP, carbon dioxide, and NADPH. On the other hand, the output molecules are ADP, sugar, and NADP.

Which of the following is the most likely reason the Moon can NOT support life?
А
It has many craters, indicating that it has an atmosphere too weak to protect life
B
It has many craters, indicating that is has a magnetic field too powerful for life.
С
It has many dark spots, indicating volcanic activity too extreme for life.
D
It has many light spots, indicating frozen ice that is too cold for life.
Answer:
A
Explanation:
B is not true because the amount of craters does not indicate how powerful the magnetic field is, it indicates how much gravity there is.
C is not true because the dark spots are igneous rock, dried lava. That means that there WAS volcanic activity, in the past.
D is not true because the light spots on the moon are not ice, they are simply a lighter colored rock.
A is true because meteors will burn up in the atmosphere of planets because of friction, so not all the meteors will hit said planet. But if there isn't an atmosphere, all of the meteors will hit that planet. (or in this case, moon)
Which behavior is both territorial and used for courtship?
1.) baring teeth as a sign of aggression 2.) sparring or wrestling using antlers or horns
3.) dance rituals with potential partners
4.)defending a nest from predators
Answer:
2.) sparring or wrestling using antlers or horns
Explanation:
Territorial behavior is defined as the animal behavior in which animals protect their territory from other species.
Courtship behavior is defined as the animal behavior that is involved in mating and eventual reproduction.
Sparring or wrestling using antlers or horns is both territorial and used for courtship. Many animals or males uses their antlers or horns for wrestling or to fight with other animals to protect their territory while some males are involved in ritualized mating behaviors that include antler wrestling (sparring). The loud vocalizations during antler wrestling show the dominance of males that females and leads to mating.
Hence, the correct answer is "2.) sparring or wrestling using antlers or horns".
