Introduced species can harm our planet because in some regions of the world we are not prepared for their type of species, which can all in all cause damage.
The cell membrane helps to transport ions, nutrients, and waste.
The correct answer is reuptake.
The reabsorption of a neurotransmitter by a neurotransmitter transporter situated along the plasma membrane of an axon terminal or glial cell after it has done its activity of conducting a neural impulse is called reuptake.
The process of reuptake is essential for usual synaptic physiology as it permits for the recycling of neurotransmitters and monitors the neurotransmitter level in the synapse, thus, monitoring the duration of the signal resulting due to the discharge of the neurotransmitter.
Mitochondria makes the energy for the entire cell, or ATP. Having two or more in a athletes muscle would be a huge advantage because the more ATP, the more endurance the muscle has.
