Answer: Lek Polygyny
Explanation:
Polygyny is a mating system inwhich one male is associated with multiple females. This mating system is found in a few birds and insects, but is most common in mammals. Polygyny is a strategy used by males to increase their reproductive fitness.
Lek polygyny is a system where male aggregate at a location and try to attract females for mating and the females leave after mating. It is believed that males attract more mate in this way than in isolation.

Answer:
Neurotransmitter
Explanation:
A neurotransmitter is a signal which transmits information between neurons at the end of the axon. This neurotransmitter can either be excitatory or inhibitory. Whenever an action potential is triggered within a neuron, the neurotransmitter releases this action potential into the synapses at the axon as either an excitatory or inhibitory signal before a new action potential is triggered.
The correct answer is: If generation 3 had flock distributions similar to those shown in the graph below.
After the change in food, the beak phenotype changes in order to adapt. So, if fruit is removed, the phenotype of birds’ beaks should change according to the change in environment. The graph below shows that there is no change, so it wouldn’t support the hypothesis that food changes beak types.
Because all organisms are made up of cells and there are different types of cells which carry different functions.
