Answer:
The correct answer is :
1) Fehling's test,
2) Tollen's test
Explanation:
1. Fehling's Test is the test that confirms the presence of aldehydes by the Fehling solution that contain copper ion with tartrate ions in NaOH solution. The color of the solution is blue due to presence of copper ions. In this test aldehydes are confirmed by the reduction of the blue solution to a insoluble precipitate of copper oxide red color while in presence of ketones there is no change.
2. Tollen's test is also a test that help in identifying the presence of aldehyde as the Tollen's reagents oxidizes aldehydes where ketones as they lack hydrogen in them.
Thus, the correct answer is : 1) Fehling's test,
2) Tollen's test.
Answer:
heat transfer is when you transfer heat from one thing to another and heat transformation is when heat is transforming into something else hope it helps
Explanation:
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
That is copied from “gene expression” article
But all in all, the cells have different structures and different jobs. This means that they are produced for that one job and cannot be made to do another job that they aren’t specifically made for. As well the dna make up will produce these cells specifically and in different cells than the other.
Hopefully this helps some. Have a nice day!
