Concept explainers
a.
To predict:
The possible outcome of Griffith’s experiment using the heat-killed pathogenic and heat killed nonpathogenic bacteria.
Introduction:
The transformation of the genetic material in bacteria was experimentally found out by the person named F. G. He was trying to make the vaccine that could cure pneumonia, which is caused by the bacteria Streptococcus pneumonia. There exist two different strains of this bacterium. One of the forms of the bacteria is known as the S (smooth) form. This strain of the bacteria is virulent and forms smooth colonies in the culture. The other form is the mutant form or the R (rough) form. This strain was non-virulent and forms a rough colony in the culture.
b.
To determine:
The possible outcome of Griffith’s experiment using the heat-killed pathogenic and live nonpathogenic in the presence of an enzyme that digests proteins (protease).

- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
