A piece of foam with an open cell structure is introduced into the wound and a wound drain is placed with lateral perforations on top. The entire area is covered with a transparent adhesive membrane, which is firmly fixed to healthy skin around the wound margin. When the exposed end of the drain tube is connected to a vacuum source, fluid is withdrawn from the wound through the foam into a reservoir for later disposal.It is necessary to cover the wound bed with a soft polyvinyl alcohol foam sponge, a non-stick oil-emulsion dressing (for exame, Johnson and Johnson), a contact layer (such as Mepitel), a thin layer of amorphous hydrogel (can be Intrasite Gel), or a calcium alginate (such as Sorbsan) before application of the gray sponge. Avoid the use of Vaseline, which is too oily and can alter the adhesion of the VAC cloth.
An ecosystem composes of an environment and the organisms that interact with said environment. Changing temperature leads to an unstable ecosystem because of two things; failure of adaptation for the environment, or failure of adaptations for the animals.
If the environment fails to adapt to a change in temperature, plants will die, thus causing herbivores to die and the whole food web/chain to disrupt. (Im not really going in to deep detail, but plants can die from the soil failing to fertilize.)
For animals, it may also disrupt the food chain, but natural resources such as water may be needed more in the heat. If said animal doesnt have the adaptations to compete in such an event, they die. Also, especially if the environment was previously a desert, all adaptations will be useless, and other animals will start to move in. More competition. Not only that, if the ecosystems temperature decreases, for example, many animals might die from the cold and such. They do not hibernate/ have the adaptations of an animal that lives in the cold.
All in all, changing temperature can cause an unstable ecosystem because it can disrupt the food chain/web, kill plants, kill animals, cause an increase of animals, cause a decrees of natural resources (such as water) and much more.
(Sorry for grammar, I'm on mobile and not really paying attention to it. im not really double checking my spelling because im trying to give you the information, not really write it for you as that would be too much work)
Most organelles are common to both animal and plant cells. However, plant cells also have features that animal cells do not have: a cell wall, a large central vacuole, and plastids such as chloroplasts.
