Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.
<h3>
What is carbon cycle?</h3>
The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.
Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.

The answer is D because bacteria is one or more cells.
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.
Over time, diabetes damages the small blood vessels in your body, causing the walls of the blood vessels to stiffen. This increases pressure, which leads to high blood pressure.
Released energy can be lost to the environment in heat form.
