D How does it occur? Tick (ü) the best explanation. ⬜ You breathe out more carbon dioxide than is in the air that you breathe in.
⬜ Small hairs in the lungs push oxygen into the blood and remove carbon dioxide.
⬜ Red blood cells enter the lungs and pump oxygen into them and let carbon dioxide out.
⬜ Particles are always moving, so naturally move into places where there are fewer of them.
⬜ Oxygen particles swim to red blood cells; carbon dioxide particles swim away from them.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

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
