Of the muscle properties, the one displayed at the moment a soccer player kicks a ball to score a goal is ? 1. contractibility since the muscles of the leg shorten in length. 2.excitability since the muscles are responding to a physical stimuli. 3.extensibility since the muscles of the leg lengthen and stretch. 4.elasticity since the muscles are returning to their normal length.

The correct option is this: EXTENSIBILITY SINCE THE MUSCLES OF THE LEG LENGTHEN AND STRETCH. 
The human muscles  have four basic properties, which are: contractility, extensibility, elasticity and excitability. Contractility refers to the ability of the muscle to contract. Excitability refers to the muscle ability to generate action potential when stimulated. Elasticity describes the capacity of muscles to go back to its original shape after been extend and extensibility refers to the ability of the muscle to stretch.

The correct answer would be b. carbon dioxide (6 co2) + water (6 h2o) > glucose (c6h12o6/ sugar) + oxygen gas (6 o2)
