Enzymes are biological catalysts that can speed up reactions by lowering the activation energy required for the reaction to occur.
In this case, the enzyme-catalyzed reaction follows zero-order kinetics, which means that the rate of the reaction is independent of the concentration of the substrate. Using the rate constant given (0.48 M/min), we can calculate the amount of substrate that will be consumed in 0.8 minutes by multiplying the rate constant by the time (0.48 M/min x 0.8 min = 0.384 M). Therefore, the remaining concentration of substrate after 0.8 minutes can be found by subtracting the consumed amount from the initial concentration (1.35 M - 0.384 M = 0.966 M). The remaining concentration of the substrate after 0.8 minute would be 0.966 M.

If the mass of each dialysis bag shown in the experimental set-up below is measured before each is immersed in its respective solution, and the mass is measured again 45 minutes later, which bag would you predict will show the greatest increase in mass?
From the understanding of hypertonic, hypotonic, and isotonic solutions; one can deduce which of the dialysis bags will show the greatest increase in mass. The correct answer would be the dialysis bag with 1.0 M solution.
Hypertonic solutions have higher concentrations than the sap of whatever cell or substances that is put into them. Water molecules will move from the sap of any cell drop into such solutions into the solutions.
Isotonic solutions have the same concentration as the sap of cells drop into them. Hence, no net movement of water molecules by osmosis.
Hypotonic solutions have lower concentrations than the sap of cells drop into them. Hence, water will move from such solutions to the sap of the cells drop into them.
In the images, there are 3 categories of solutions:
Hypertonic solutions: the solutions with 1.0, 0.4, and 0.6 M concentrations. The dialysis bags with 0.2 M solutions will lose water to their respective surrounding hypertonic solutions. Hence, their weights would decrease.Isotonic solution: the solution with 0.2 M concentration, the same concentration as the solution in the dialysis bag. The dialysis bag will neither gain nor lose weight.Hypotonic solution: the solution with 0.2 M concentration but the concentration of the solution in the dialysis bag is 1.0 M. Water molecules will move from the surrounding solution into the solution in the dialysis bag. Hence, the dialysis bag in this case will gain weight.In other words, the dialysis bag with 1.0 M solution will have the greatest increase in mass due to a gain in water molecules by osmosis.

A bacteria has an initial population of 500 and is doubling every hour. the bacteria reaches a population of 16,000 bacteria. which equation could represent the situation described and how long does it take for the bacteria to reach 16,000?
So it takes approximately 5 hours for the bacteria population to reach 16,000. The equation representing the situation is:
Population = 500 * 2^(Time)
To represent the situation described, where a bacteria population of 500 doubles every hour and reaches a population of 16,000, you can use the exponential growth equation:
Population = Initial Population * (Growth Rate)^(Time)
In this case, the initial population is 500, the growth rate is 2 (since the population doubles every hour), and the final population is 16,000. To find the time it takes for the bacteria to reach 16,000, we can set up the equation:
16,000 = 500 * 2^(Time)
To solve for the time, follow these steps:
1. Divide both sides of the equation by 500:
16,000 / 500 = 500 * 2^(Time) / 500
32 = 2^(Time)
2. Now we have to find the exponent (Time) for which 2 raised to that power equals 32. We can use the logarithm to do this:
log₂(32) = Time
3. Calculate the logarithm:
Time ≈ 5
So it takes approximately 5 hours for the bacteria population to reach 16,000. The equation representing the situation is:
Population = 500 * 2^(Time)

Phenylketonuria (PKU) is an inherited disease caused by a recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability that all three children have the disease
The probability that all three children of carrier parents will have PKU is low, at only 1.56%. However, it is important to consider the probability of each pregnancy independently, as there is a 25% chance of each child inheriting the disease.
Phenylketonuria (PKU) is a recessive genetic disorder caused by the presence of two copies of the mutated gene. If both parents are carriers of the disease, they have a 25% chance of having a child with the disease, a 50% chance of having a child who is a carrier like them, and a 25% chance of having a child who is not affected by the disease and is not a carrier.
So, if a woman and her husband are both carriers of PKU, the probability that all three of their children will have the disease is (0.25 x 0.25 x 0.25) or 0.0156, which is a very low probability. This means that there is only a 1.56% chance that all three children will inherit the disease.
However, it is important to note that each pregnancy is an independent event, which means that the probability of having a child with PKU is the same for each pregnancy. Therefore, even if the first child is not affected by the disease, there is still a 25% chance that the second and third children may have PKU.

When objects of two different temperature are in contact, what happens?
Answer:
The answer is C.
Explanation:
This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.
What change in temperature when object are in contact?It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.
Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.
The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.
Therefore, The warmer object transfer heat energy to the cooler object.
