If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
Answer:
The correct answer is : decreases
Explanation:
The development of the peppered moth is a transformative event of directional color change in the moth populace as a result of air contamination during the Industrial Revolution.
The melanic or dark color type of the peppered moth was not known before pollution level was low before 1811. Hence the decrease in pollution level in atmosphere will lowers the frequency of the melanic form of peppered moths.
Thus, the correct answer is : decreases.
Answer:
Three types of population distribution:
Clumped.
Random.
Uniform.
Explanation:
1. Clumped:
This is the most common pattern of population dispersion.
organisms are clustered together in a group.
This may reflect the patchy distribution of resources in the environment.
2. Random:
This is a typical distribution where individuals do not interact strongly.
The organism has unpredictable distribution.
3. Uniform:
This is the typical environment where individuals compete with each other for scarce resources like water in the desert.
organisms are evenly spaced over the area they occupied.
