Monkeys have a prehensile tail that allows them to grab and hold onto tree branches.

structural adaptation

Explanation:

Adaptation is the way the organism is kept alive in changing life circumstances. Every organism in a dynamic relationship with the environment tends to survive.

Ecological factors determine the living conditions in one habitat. This means that all plants, animals, fungi, and even microorganisms adapt to the conditions

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
