PLS HELP! A single celled organism that lives in extremely hot or acidic environment with no membrane-bound organelles most likely belongs to 1. archaea, bacteria, and eukarya
2. archaea and bacteria
3. archaea only
4. bacteria only​

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

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
