Answer:
A. All of the offspring plants will have purple stems.
Explanation:
All of the offspring plants will have purple stems because both the parents have the same stem color i. e. purple so if they mate with each other , the offspring produce have the same color of stem. Both parents plants are heterozygous which means that they are different from one another in some characteristics but also some similarities such as stem color etc. So all the offspring produce have purple-stemmed.
Control Group: Group that is being controlled .This group doesn´t receive the treatment from the researchers
Experimental Group:Group that is being Experimented and that receives the testing
Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.
As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
<h3>What is Genetic material?</h3>
Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.
In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.
These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.
Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

Answer:
Basically, together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
