A student wants to investigate osmosis. A carrot was placed in a dilute solution.
a) What will happen to its mass?
b) The carrot was placed in 0.4 mol/dm 3 solution. Its mass did not change.
c) What does this tell us about the concentration of the carrot?
d) The carrot was placed in a concentrated solution. What will happen to its mass?
a) When a carrot is submerged in a diluted solution, water will osmosis into the carrot cells. As a result, the cells will become turgid and the carrot's mass will rise.
b) The carrot's inability to alter in mass when submerged in a 0.4 mol/dm3 solution shows that the solute concentration—which includes salts and sugars—within the carrot cells is also 0.4 mol/dm3. There is no net movement of water into or out of the cells at this concentration.
c) This indicates that the carrot and the 0.4 mol/dm3 solution have come to an equilibrium. At this concentration, the passage of water into and out of the cells is balanced, and there is no net gain or loss of water.
d) If the carrot is submerged in a concentrated solution, water will osmotically escape from the cells, plasmolyzing them. The mass of the carrot will shrink as a result.
OsmosisOsmosis is the transfer of water molecules from a region with a high concentration of water to a region with a low concentration of water through a membrane that is selectively permeable. Since a diluted solution contains more water molecules than carrot cells do, water will osmotically flow from the fluid into the cells. The carrot cells become turgid, which is another word for inflated and hard, as a result of this water inflow. The carrot's mass so grows as a result.The carrot's inertness in a 0.4 mol/dm3 solution shows that the solute concentration inside the cells of the carrot is also 0.4 mol/dm3. At this concentration, there is no net gain or loss of water since the flow of water into and out of the cells is balanced. This is due to the fact that the solute concentration in the carrot cells and the solution are the same. Isotonic describes this condition.learn more about osmosis here

When two DNA fragments with complementary sticky ends join, the activity of dna ligase ensures that the join is permanent is catalyze the formation of a phosphodiester bond they form a stable bond.
DNA ligase has a unique property that enables it to catalyze the formation of a phosphodiester bond between the 3'OH of one nucleotide and the 5' phosphate of the other, resulting in the formation of a new phosphodiester bond and the loss of a water molecule (dehydration reaction). When two DNA fragments with complementary sticky ends join, the sticky ends anneal to each other, and the base pairs form hydrogen bonds. This creates a short-lived intermediate that can be further stabilized by the action of DNA ligase. The DNA ligase enzyme then binds to the junction of the two strands and catalyzes the formation of a phosphodiester bond, joining the two DNA fragments permanently.
This occurs through a complex series of reactions that involve a high degree of specificity and accuracy. The binding of the DNA ligase enzyme to the DNA ends is driven by specific recognition sequences that are present on the DNA fragments. These recognition sequences allow the enzyme to bind to the DNA and guide it towards the correct site of ligation. Overall, DNA ligase ensures that the join is permanent by catalyzing the formation of a covalent bond between the two DNA fragments. This reaction is specific and accurate, ensuring that the two fragments are joined together in the correct orientation and position.

At midnight, the leaf of a plant undergoes several changes, including physiological and metabolic activities. Plants undergo changes in metabolic activities even when they are not in the process of photosynthesis.
During the day, the leaf of a plant carries out photosynthesis and other metabolic activities. However, at midnight, plants cease all activities, including photosynthesis. The leaf of a plant has stomata that allow gases to enter and exit the leaf. These gases are vital in the process of photosynthesis, where carbon dioxide enters and oxygen leaves the leaf. At night, the stomata close, and no more gases are exchanged. The stored carbon dioxide is converted into glucose and other sugars. This process is called respiration. Respiration is essential for the survival of plants because it produces ATP, the energy currency of the plant. Plants also undergo a process called transpiration, where water is taken up through the roots and exits through the stomata. At night, the stomata are closed, and the plant conserves water. However, there is still some transpiration going on in the leaf, but at a much slower rate. In conclusion, at midnight, the leaf of a plant is not carrying out photosynthesis, but it is still undergoing metabolic activities, such as respiration and transpiration.

fat leaves the chylomicron and moves into adipose cells when the chylomicron come into contact witha. ribosomeb. antibodiesc. lipoprotein lipase
When chylomicrons come into contact with lipoprotein lipase (LPL), fat leaves the chylomicron and moves into adipose cells. Therefore, the option that represents the correct answer is C. Lipoprotein lipase.
Lipoprotein lipase (LPL) is an enzyme that catalyzes the hydrolysis of triglycerides in chylomicrons and VLDLs (very-low-density lipoproteins) into glycerol and free fatty acids, which are transported into the adipose tissue for storage, muscle tissue for energy use, and other organs for various functions. LPL is produced by adipocytes, skeletal muscle cells, and the heart.
Therefore, this enzyme is found on the endothelial surface of blood vessels in the tissues where the triglyceride-rich lipoproteins come into contact. the fat leaves the chylomicron when they come into contact with lipoprotein lipase (LPL).
