Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells.
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.
Unbalanced,
Na + Cl2
Na = 1
Cl = 2
NaCl
Na = 1
Cl = 1
Basically, both the reactants and products must have equal amounts of each element.
Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
