To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same am
ount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?
The correct answer would be - container 2 will have less salinity than container 1.
Explanation:
The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.
We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1
If a document needs to be passed on to another person for assignment, you would delegate it. When you delegate something you pass it to someone to entrust them with the task. The correct answer is C.
Answer: The protein will be a substrate for protein kinases
Explanation: Kinases are a class of enzymes that catalyze the addition of a phosphoryl group to a protein. The kinase will add a phosphoryl group to the protein at its serine/ threonine residues.
