Explanation:
When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity? a) the ions in the solution interact with the sugar and that interferes with its solubility b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
The correct answer is option c.he solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
The Solution contains a solute (sucrose for this situation) and dissolvable (water for this situation). A saturation or unsaturation of a solution relying upon whether it can even now dissolve a solute or not.
As indicated by this inquiry, the sucrose solution is saturated as the 0.7 M sucrose arrangement doesn't disintegrate the sucrose (solute) anymore. The immersion of the sucrose arrangement happens in light of the fact that the measure of solutes is likening the number of solvents in the solution. The solubility of a particular solution relies on saturation.

A student wants to test the effect of different amounts of caffeine on the heart rate of dogs. Describe the experimental groups in this experiment. What is the dependent variable? type of dogs amount of caffeine the heart rate number of dogs
Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.
How can I solve -10(-5)+3 someone give me an example:)
Answer:
the answer is 53
Explanation:
step 1: Multiply -10 and -5 together that will give you 50.
( it is positive because whenever you multiply or divide 2 negatives together it becomes a positive.)

A)
a decrease in the concentration of hydrogen and oxygen
B)
an increase in the concentration of hydrogen peroxide
C)
an increase or decrease in pH beyond normal range

Which toy car had the greatest applied force?
A 1
B 2.
с 3
D4
Answer:
the answer is 4
Explanation:
i dont know how to explain it but i took the test and it was right.
The car with the greatest applied force is : ( D ) Car 4
Given that :
Force applied is calculated as : Mass * acceleration
Calculating the force applied on each carFor Toy car 1
mass = 0.19
acceleration = 0.15
Force = 0.19 * 0.15 = 0.0285 N
For Toy car 2
mass = 2.0
acceleration = 1.5
Force = 2 * 1.5 = 3 N
For Toy car 3
mass = 0.25
acceleration = 0.21
Force = 0.25 * 0.21 = 0.0525 N
For Toy car 4
mass = 2.5
acceleration = 3
Force = 2.5 * 3 = 7.5 N
From the answers above the car with the greatest applied force is car 4 with a force of 7.5 N
Hence we can conclude that The car with the greatest applied force is : ( D ) Car 4

What is a disadvantage of a 2D model of the digestive system?
Answer:
The disadvantage of 2D model of the digestive system is that it decreases cell to cell interaction and it is not a very important biological model.
Explanation:
The 2D model does not show quality similarity and resemblance to the main digestive system and also fail to reveal the interaction of cell surfaces of each other, it does not provide the quality detail of biological systems in digestive systems and this model is not very important or relevant biological model because It does not provide quality detail.
Most fad diets focus on restricting certain types of food and nutrients. What do you think would happen if someone ate an extremely low-protein diet without the approval of a doctor? What side effects might the person experience?
Answer:
Eating a diet of low levels of protein could leave you to development a condition called edema, which causes swelling in your legs and feet from the buildup of fluids. Protein plays an essential role in maintaining salt and water inside your blood vessels and ensuring fluid does it make its way into the tissues. Hajima can cause stiffness, difficulty walking, increasingly painful swelling.
Explanation:
Answer:
Here’s one possible answer:
Protein builds and repairs body tissues. So, a person who eats a low-protein diet might experience symptoms such as slow wound healing. This person might also start losing muscle mass because the body uses skeletal muscle to make protein when needed.
