The most likely answer choice should and would be B, given that rabbits are herbivores (meaning that they only eat vegetation and plants, including grass). Buffalo's food source(s) and diet consists of grass as well. If enough rabbits are introduced into a grassland area, they will furthermore consume more grass, in turn limiting the food source of the buffalo.
''Attacking'' prey doesn't necessarily make sense, given that buffalos do not 'prey' on any animal and rabbits themselves are prey.
A to a lesser extent can make sense, although I doubtable. B's most likely the answer.
Answer:
The correct answer is "I would suggest her to change the Gram positive control from Bacillus subtilis to other bacteria".
Explanation:
Bacillus subtilis, and the species from the genre Bacillus, are known for losing the crystal violet coloration during Gram testing. It is likely that B. subtilis might look pink under the procedure for this reason. I would suggest to change her Gram positive control from B. subtilis to other bacteria. For instance, she could try with Staphylococcus aureus, a widely used bacteria as Gram positive control.
The correct answer is c trachea
It couldn't be analysed chemically because it's chemical composition is to complex. It would be hard for us to analyse them because once it has been removed from the organism, it ends as protoplasm only.
