The layers of rocks, the ancient treasures that are at the bottom of the sea, how old the coral is. But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.
Blood flow to the heart via the following vessels:
1. superior vena cava
2. inferior vena cava
4. coronary veins/sinus
Answer:
Aquaporins
Explanation:
Aquaporins are the channel proteins that is present in the membrane of the cell which allow water to cross the membrane very quickly. This aquaporins play an important roles in plant cells, red blood cells, and certain parts of the kidney where this protein minimize the amount of water lost as urine. Without this protein, the diffusion of water across the cell membrane is not possible very quickly.
In order to float in water, the density of an object has to be less than the density of the water. Since saltwater has a higher density than fresh water, a person will float more in the ocean than they would in a lake
From glucose
ATPs are produced.
ATP:
- One glucose molecule is divided into two pyruvate molecules during glycolysis, requiring two ATP molecules while generating four ATP molecules and two NADH molecules.
- For the cell to utilize as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules.
- Glucose breaks down into pyruvate and energy during glycoses
- From glucose 6- phosphate to lactate 3 ATPs are produced.
ATPs are generated from which one is utilized when fructose
phosphate is converted to fructose
bisphosphate. So the net yield is
ATP.
From dihydroxyacetone phosphate 2 ATPs are produced.
As the cycle occurs only once either from DHAP or PGAL (glyceraldehyde
phosphate)
Three irreversible reactions of glycolysis:
Hexokinase
Glucose + ATP
Glucose
phosphate + ADP
Phosphofructokinase-I
Fructose
phosphate + ATP
Fructose
bisphosphate
ADP
Pyruvate kinase
Pyruvate
ATP
