What is required in all living things in order for gas exchange to occur?
In any living organism that needs to breath, the only thing consistently required for life is the presence of moist membranes. The movement of oxygen and carbon dioxide across the membranes between the environment and the respiratory surface occurs by diffusion. Respiratory surfaces are generally thin and, since living animal cells must be wet in order to maintain their plasma membranes, these respiratory surfaces must be moist.
How does exchange of gases takes place in unicellular organisms?
In unicellular organisms, gases are exchanged through simple diffusion across the cell membrane. Oxygen from the environment diffuses into the cell, while carbon dioxide produced by the cell diffuses out. This process is driven by concentration gradients, where gases move from areas of higher concentration to areas of lower concentration.
Which of the major plant divisions contains that must live in a moist environment because they do not have a system for conducting water throughout the organism?
Bryophytes, which include mosses, liverworts, and hornworts, are the major plant division that must live in a moist environment due to their lack of vascular tissue. Without vascular tissue to transport water and nutrients, bryophytes rely on direct absorption through their cells, requiring a moist environment for survival.
Why must fern live in moist environment?
Ferns live in moist environments to transport water to cells.
Why do amphibians need moist skin?
Amphibians need moist skin to be able to easily adapt to dry land or the water. This is because an amphibian's respiratory system must be able to adapt to either condition and thin, moist skin makes this easier.

How does gas exchange take place?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.

Describe all the ways the earthworms are like humans?
Earthworm are like human cause they have a complete losed circulatory system. The earthworm has red blood that contains respiratory pigment similar to hemocfokin. External respiration in human must be moist and an earthworm keep its body surface.
What are the requirements for an efficient respiratory organ?
An efficient respiratory organ must have a large surface area to facilitate gas exchange, allowing for sufficient oxygen uptake and carbon dioxide elimination. It should also be thin-walled to minimize the distance for diffusion, and highly vascularized to ensure effective transport of gases to and from the bloodstream. Additionally, the organ should maintain a moist environment to enhance gas diffusion and be adaptable to varying environmental conditions.
What Must Happen to Cause A Response in an Organism?
Something must change in the internal or external environment of the organism. This change can be physical or chemical and will result in a response from the organism. The scientific name for these changes are stimuli (singular = stimulus), examples of which are touching a hot surface, being scared, exercising and drugs. Hope this helps

In order for clouds to form the air must be what?
The air must be moist.
What are the advantages of water as respiratory media to aquatic animals?
If an animal lives in the water, it is an advantage to be able to get oxygen from the water. If the animal must breathe air, then it has to surface frequently. If it is unable to surface for some reason, it will drown.
How do you dress the exposed intestines or organ?
You must cover it with moist saline dressings.
Why must fern live in moist environment?
Ferns live in moist environments to transport water to cells.
Organism that must feed on another organism in the environment?
A Predator.
