How can reproductive isolation lead to speciation<span>? If populations cannot mate successfully with one another, genetic differences may accumulate in the populations. Over time they become very different and give rise to new species.</span>
4. nucleoid region
Bacterial cell's do not have a nucleus; their DNA is found in this region.
I think it's oxygen and water because they are the substance for cellular respiration.
The correct answer is neuroplasticity.
Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.
