Answer:
Change their external environment is the correct answer.
Other than contributing to potential increase in diversity of species in an ecosystem, exotic species have positive benefits like removing toxins from the soil, regulating erosion, and controlling undesirable species.
Answer:
The inhibitory transmitter activates ligand-gated potassium channels
Explanation:
When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.
However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
The answer that is true of meiosis is that D) it divides one diploid cell into four haploid cells.
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.
