The sympathetic and parasympathetic divisions of the ans have the same effect on most body organ systems. a. true b. false

The correct answer is false.

Parasympathetic nervous system (PNS) and sympathetic nervous system (SNS) are functionally different parts of ANS.

PNS controls homeostasis of the body. It is responsible for the body's "rest and digest" function which means that is active when the body is at rest. For example, it decreases the heart rate, relaxes muscles, constricts bronchial tubes, increases production of saliva, increases urinary output.

SNS, on the other hand, is involved in the body's fight-or-flight response, although it is active at a basic level to maintain homeostasis. SNS increases contraction and heart rate, dilates bronchial tubes, contract muscles, releases adrenaline.

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

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
