g If you look carefully at this organism, you will not see any organs for gathering oxygen or releasing carbon dioxide or ammonia. There is no circulatory system. How does this animal perform these functions

Simple unicellular organisms like Amoeba and some multicellular organisms like Hydra use their cell surface and skin for gaseous exchange with their environment.

Note: The organism in the question was not stated.

Explanation:

The complexity of an animal determines its metabolic needs, and hence, its requirement for specialized structures and functions.

Simple unicellular organisms are able to meet their metabolic needs such as gaseous exchange by simple diffusion through their cell surfaces. Such organisms include amoeba, paramecium, etc.

Some multicellular organisms lack specialized organs for nutrient transport and gaseous exchange such as hearts and blood vessels, etc. Example of such organisms are Hydra and Planaria. They have their cell surfaces in contact with the external environment, and thus use their skin for gaseous exchange by means of diffusion.

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.
