B. ventricles
The chordae tendinae, also referred to as heart strings, are tendons that connect the atrioventricular (tricuspid) valves to the muscular wall of the heart. These chords are made predominantly of collagen, while the remaining part is elastin. They play the vital role of maintaining the structure of the valves they connect to. Due to the high pressure generated within the heart, it is entirely possible for the atrioventricular valves to turn inside out. The chordae tendinae prevent this from happening and keep the valves functioning properly.
I know accurate is really close or exact but the reproducible ive never heard
The answer is; they are both autotrophs
These types of organisms make their own food from abiotic factors. The plants at the meadow make their carbohydrates using energy from sunlight. The bacteria convert the inorganic sulfur into organic molecules. The plants are called photoautotrophs, and the bacteria are chemoautotrophs.
