Answer:
The correct answer is - leads.
Explanation:
In ECG or electrocardiogram, a test that is used to measure the electric activity of the heart of an individual, each electric impulse cause a electric wave to travel through the heart and cause the heart pump to pump blood.
There are electrodes that received the electric impulse in this machines, electrodes have self adhesive pads and attached with various leads mostly 12, that carries the impulses in the combinations that are recorded on the ECG.
Thus, the correct answer is - leads.
This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
I think it is rising sea level
The correct answer is option D, that is, ice floating on the water surface.
The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.
The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.
The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.
