High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater). This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.
<h3>What is the importance of oxygen for marine animals?</h3>
It is necessary for fish and other aquatic organisms to survive. Because of the aerating action of the wind, oxygen dissolves in surface water.
As a byproduct of aquatic plant photosynthesis, oxygen is also introduced into the water. Fish and other aquatic organisms cannot survive when dissolved oxygen levels fall too low.
High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater).
This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.
Thus, these are the effect of high carbon level have the deep ocean.

The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.
The cell membrane is flexible because of the presence of oil like substances called phospholipids, which gives it a fluid nature. While as the cell walls are rigid because of the presence of the thick layers of the substances like cellulose in plants, chitin in fungi and peptidoglycon in bacteria.
Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.
- An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
- The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
- The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
- To aid in preventing fraud, MINs and ESNs can be electronically checked.
