Natural selection affects the scope of the niche of a given species. Moreover, trade-offs are associated with differences in traits that also may affect the niche of a species.
<h3>Natural selection and trade-offs </h3>
Natural selection refers to the differential survival or reproduction of individuals in particular environmental conditions.
The different niches occupied by species are mainly a consequence of differential trade-offs among species, i.e., by differential phenotypic features that generate negative correlations among species.
Grime’s Triangle is based on the associations (trade-off) between adaptation to productivity and/or competition, stressful environments (habitats) and disturbance.

Answer:
Infection would be the answer for the blank
The answer is d. dormancy.
Dormancy is physiological condition during which growth and development are temporarily stopped. The aim of this condition is to preserve energy by minimizing metabolic activity, usually because of inadequate environmental conditions.
Dispersal refers to movement of individuals from one site to another. Fertilization means a fusion of gametes to develop a new organism.
Germination is a process of growing plant from a seed.
Explanation:
The main activity that occurs at the transmissive segment is the release of neurotransmitter from synaptic vesicles . Prior to the arrival of the action potential, Ca2+ pumps embedded in the plasma membrane of a synaptic knob establish a calcium concentration gradient by pumping it out to the IF. Consequently, there is more calcium inside of the synaptic knob than outside it.
Further Explanation:
At synaptic junctions:
- The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing Ca2+ to rush into the terminal due to higher extracellular concentrations
- these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters
- this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily
- This leads to activation of specific complexes, enabling the transmission of information. Thus, the chemical signal is transferred through this neuron as an electrical impulse
