The law of conservation of mass states that atoms cannot be created not destroyed, so they could not have destroyed it. This means that the experiment had to be open (which means there is no barrier that keeps all the solution in, like a plug or a bag). When the liquid in the equation turned into gas, the gas floated away from the solution, making the ending mass smaller than the beginning.
Answer:Cell cycle
Explanation:
It's a series of events that take place in a cell leading to duplication of its DNA and division of cytoplasm and organelles to produce two other cells.
Answer: Earth's main sulfur sink is the oceans SO42−, where it is the major oxidizing agent. When SO42− is assimilated by organisms, it is reduced and converted to organic sulfur, which is an essential component of proteins.
Explanation:
B biuret, this is because it is a test for proteins and an enzyme is a protein catalyst in an organism.
Answer:
Explanation:
Cloning is to make a genetically exact copy of it. A gene or other small piece of DNA is mostly cloned.
DNA cloning is the process of making multiple copies of a particular piece of DNA that are identical.
The DNA fragment of the human is first inserted into a plasmid which is a circular form of Dna. Enzymes “cut and paste” the DNA into the plasmid and it produces a molecule of recombinant DNA. The plasmid and gene fragment are joined together to produce a gene containing plasmid which is a recombinant DNA.
The recombinant plasmid is then introduced or inserted into the bacteria, the bacteria that carries the plasmid are selected and grown. As the bacteria reproduce, they replicate the plasmid and it is also passed to their offspring.
