I think the correct answer from the choices listed above is option B. Koalas are the least likely to survive a change in its ecosystem because they only eat eucalyptus leaves. They have limited food as compared to the other choices which are able to thrive at various conditions.
I believ the answer is c but if not i am super super sorry!!!
1. Griffith in his experiment used two related strains of bacteria (Streptococcus pneumonia), known as R and S and mice, trying to develop a vaccine against pneumonia. R strain-formed nonvirulent, rough-edged colonies
S strain- rounded and smooth colonies, with sugar protection coat, virulent
Mice that were injected with S strain developed pneumonia and died.
But, when mice were injected with heat-killed S strain it did not cause disease in mice.
The next part of experiment is the injection of combined harmless R bacteria with harmless heat-killed S bacteria. The result was that the mouse developed pnenumonia and in blood sample from the dead mouse, living S bacteria were found.
2. From his experiment, Griffith concluded that injected together, R strain and S strain bacteria most likely “communicate”. The R-strain bacteria took "transforming principle" (we know today that this is genetic material DNA) from the heat-killed S bacteria which allowed them to "transform" into virulent bacteria.
Alright! Your being asked to rank a group by there taxonomy. You can remember this for a test by using "Dear King Phillip Came Over for Good Soup" or domain, kingdom, phylum, class, order, family, genus, species. So rank them from least to most specific. See you if you can figure it out with that!
Answer:
The osteoblasts, which should have been building the new bone
Explanation:
Osteoblast are the cells that build bones by secreting the extracellular matrix for bone tissue. These cells secrete components such as collagen fibres and inorganic electrolytes that together make the matrix of bone tissue. Absence or inactivity of these cells could prevent the formation of new bone after fracture. Hence, doctors should target osteoblasts.
