The ability of organisms to regulate and thus maintain a relatively stable internal environment, despite external pressures, is called HOMEOSTASIS. This word comes from two Latin/Greek root words: "homeo" and "stasis".
"Homeo" means constant or unchanging. And "stasis" or "static" refers to stillness, non-movement. So, together, we can translate Homeostasis into a constant stillness inside, which makes sense for "maintaining normal internal states."
Answer:
Y= 98, 0% , Z = 94,7 %
Explanation:
We use simple 3 rules to find the percentage of purity, using mass data:
Sample Y =
85g----100%
83,30g----X = (83,30gx 100%)/ 85g= 98, 0%
Sample Z =
95g----100%
90g----X = (90gx 100%)/ 95g= 94, 7%
Data collected by the drilling ship Glomar Challenger confirmed that C. NONE OF THE OCEAN FLOOR IS MORE THAN 180 MILLION YEARS OLD.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earht's mantle.
C. The nervous system sends signals to make muscles move.
