The horned lizard can confuse a predator by shooting blood from it's eyes, with control over the height (up to 5ft) and the direction of the blood.
Oxygen is needed by aerobic organisms for cellular respiration process. Oxygen happens when the muscles are working faster than energy can be produced. Energy is still produced but anaerobic process is done to cope up. The signs of oxygen debt are panting and muscle fatigue.
Explanation:
In amoeba respiration takes place through its cell membrane also called the plasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion. The oxygen gas diffused inside the body is used up by the amoeba. In the body, the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba, the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.
Since amoeba needs oxygen for respiration, the type of respiration is aerobic respiration.
Carbon dioxide—\text {CO}_2CO

Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.
Some human activities, such as burning of fossil fuels and deforestation, increase atmospheric \text{CO}_2CO
