Answer:
option A
Explanation:
In carrying out these experimental procedure, the same restriction enzyme that is used to cut out the gene of interest should also be the same used for the cutting of the plasmid to generate sticky ends. Then the desired gene is inserted into the cut plasmid then treatment with DNA ligase. Purified DNA ligase is utilized in gene cloning to join/ligate DNA molecules together forming a recombinant DNA. Thus, step 3 should be carried out after step 4.
Answer:
Virus.
Explanation:
Viruses can't reproduce without invading the cell of another living being.
Answer:
Bone strength is influenced by changes in the structure (size and shape) and composition [cortical (compact) bone, trabecular (sponge-like) bone, amount of cartilage] of the bone. 6 A high peak mass at a young age and the decrease of bone loss at a later age are two ways to reduce osteoporosis risk.
Explanation:
Answer:
The correct answer is- make a prediction
Explanation:
A hypothesis can be defined as an explanation of any observation which can be confirmed by experiments and prediction is the guess about the future result of any observation.
As here a biologist hypothesized that the sound produced by frog is mating calls than the next step of the biologist would be to make a prediction about response of that mating call by female frogs. This is called hypothesis prediction method.
Therefore the right answer is- biologist will make a prediction.
