Answer:
Pig
Explanation:
Pigs are mammals and have organs and lungs and hearts, while the rest do 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.

In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual has two or more cell populations with a different chromosomal makeup, this situation is called chromosomal mosaicism. Chromosomal mosaicism occurs from an error in cell division in cells other than eggs and sperm.
There are usually fewer organism at the top pyramid levels because there is much less energy available
