Answer:
1. sympathetic
2. parasympathetic
Explanation:
The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.
Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Answer/Explanation:
Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.
Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.
On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.
