Hi lovely! Here are your scientific questions that are testable:
Does the type of liquid affect how fast an ice cube melts?
Does changing the temperature of water affect the buoyancy of an egg?
Does the thickness of the wire affect the power of the circuit?
Hope I helped!
The answer is B. guidelines for safe laboratory practices
I would go with b? That just in my opinion tho
Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
