8_murik_8 [283]

Answer:

Industrial Revolution

Explanation:

In the 18th century, the industrial revolution took place. People started having more jobs than before and also getting paid for their labor. As the workers and employees were getting paid and jobs were available because of the industrial revolution, people started buying goods for their families. As a result, the standard of living also went up. Also, there was enough food for families to grow. As a result, the total population increased.

The output region is the site of ______________________.
tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.

elena55 [62]

Answer:

3. B. no new mating partners are available

7. D. best adaptations

8. C. survive and reproduce

Explanation:

Carrying capacity refers to the maximum population size of a species/population in a particular habitat. The carrying capacity depends on abiotic (e.g., shelter, water) and biotic factors (e.g., food, presence of mates). According to the evolutionary theory, individuals better adapted to their environments are more likely to survive and reproduce (i.e., produce more offspring) than other members of the same species. These 'better adapted' individuals will have more chances to pass their 'beneficial alleles' to the next generation.
