There are three slopes in a survivorship curve, which indicates the average life expectancy of a population.
Type I<span> or convex curves in which few offsprings are produced, but they are cared well and get matured and survive.
</span>Type II or diagonal curves where al almost constant rate of birth or mortality is observed.
Type III or convex curves where high mortality is observed in early life, but the aged population has a high survival rate.
If the tank is a small one and filled with freshwater, an activity performed by a student that is investigating an abiotic factor using the setup would be to record the temperature of the water.
Answer:
Visceral motor
Explanation:
Peripheral nervous system is divided further into visceral and somatic nervous system. Somatic nervous system controls the skeletal muscles, joints and tendons. Visceral nervous system controls cardiac muscles, glands and smooth muscles.
Large intestine has smooth muscles so it is controlled by the visceral nervous system. It has further two divisions, sensory and motor. Sensory division carries signals from the muscle to the central nervous system whereas motor division carries signals from the central nervous system to the muscle which cause an action. Hence, visceral motor division carries signals to the smooth muscle in the large intestine.
