Answer:
Both organisms benefit in cooperation and competition, but only one benefits in predation.
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
Answer:
C. This is an example of VNTRs.
Explanation:
VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
