the haze effect is the right answer
Answer:
When we compare the feeding of larvae with royal jelly to raise queen bees with turning off the Dnmt3 gene
It can be said that the latter is more effective in terms of the number of queens that can be produced and the energy expenditure is much lower. Well, keep in mind that bee larvae only become queens when they receive large amounts of royal jelly. A royal jelly protein is what activates the mechanisms to be a queen bee, this jelly machinery the nurse worker bees.
Through genetic manipulation, the Dnmt3 gene can be turned off in any larva to produce a queen bee.
Answer:
parasitism, commensalism
Explanation:
Parasitism is a form of interaction between two organisms in which the parasite lives on the host, obtain all its nutrients from the host and end up stifling the growth of the host. In summary, parasites reduce the fitness of their hosts by gradually killing them.
Commensalism is a form of interaction between two organisms in which the commensal benefits and the host is unaffected. The fitness of the host neither decrease nor increase.
Hence, when ticks (which feeds on the blood) reduced the fitness of white-footed mice in 2012, it is a parasitic relationship. When the blood feeding had no effects in 2013, it is a form of commensalism.
