Human muscle cells are facultative anaerobes that perform lactic acid fermentation when oxygen is depleted from muscle tissues .During periods of high physical activity, such as a 100-meter sprint ,ATP is tepidly used from muscle contraction .The limited oxygen delivered to muscle cells becomes a problem ,and aerobic respiration is blocked .In anaerobic respiration, the ATP provide by rapid fermentation, temporary provides energy to maintain muscle function in the absence of oxygen until oxygen levels are restored . Yeast also performers cellular respiration in the obsence of oxygen , a process called alcoholic fermentation. what are two products of arcoholic fermentation?

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

idk lol use google m8

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
