What are Smooth muscles?
Because it lacks sarcomeres and as a result, striations, smooth muscle is an involuntary non-striated muscle (bands or stripes). Its two subgroups are single-unit smooth muscle and multi-unit smooth muscle. A syncytium is the collective contraction of the sheet or bundle of smooth muscle cells that make up a single-unit muscle.
Smooth muscle makes up the walls of hollow organs including the stomach, intestines, bladder, and uterus as well as the blood and lymphatic vessels, as well as the tracts of the respiratory, urinary, and reproductive systems. The ciliary muscle, a type of smooth muscle present in the eyes, changes the shape of the lens by dilation and contraction of the iris.

Answer:
B, lung cell, lung tissue, lung, pulmonary system
Explanation:
Lung cells are also called as pleural cells. Lung cells to form lung tissue which then forms the lung and lung and its function forms the pulmonary system. The complexity increases from cell to organ system.
Pulmonary system plays a major role in respiration. Lung cells once damaged are slow to regenerate. Alveoli are the sacs in the lungs that take up the oxygen from the inspirited air and then transfers it to the tissue.
Answer:
When a species organism starts living on a land, its population starts to increase if conditions are favorable for its survival. The population will increase rapidly at first because there will be enough resources such as water, food, light, shelter etc. This will be the R constant in a graph.
As the population will increase rapidly, the resources will start getting depleted and competition will begin among the snake population for resources. As a result, the population will start to decline which will be the R declining phase.
Finally, the population will achieve its carrying capacity rate which will be R 0, after the declining phase. This phase will be ideal for the survival of the snake population on the Pacific Island.
