The correct answer is a structure that would differentiate the hollow heart into chambers to separate oxygenated blood.
The heart has four chambers: two ventricles and two atria. The right atrium gets oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-deficient blood to the lungs.
The left atrium gets oxygen-enriched blood from the lungs and pumps it to the left ventricle, and the left ventricle pumps the oxygen-enriched blood to the body. The right and left atrium are distinguished by a wall of tissue known as the atrial septum, and the left and right ventricles are separated by the ventricular septum.
Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).
Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
Human,increase population and Overharvesting
Amount of food in stomach when drinking, body weight, rate of consumption, strength of alcohol.
