Answer:
Water moves across a permeable barrier during osmosis to equalize the solute concentration on each side of the membrane. Nutrients, on the other hand, are absorbed across a barrier by a process known as diffusion
Explanation:
Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Diffusion is the process by which atoms or molecules move from an area of high concentration to low concentration
Answer:
<em>Skeletal muscle – the specialised tissue that is attached to bones and allows movement. </em>
<em>Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. </em>
<em>Cardiac muscle – the muscle specific to the heart.</em>
Answer:
Arrhythmia can be described as irregular heart beat, when the heart of a person is beating either too quickly of too slowly, with irregular rhythms.
Explanation:
The major risk factor associated with digoxin-induced arrhythmias is death.
New research has shown that people who have arrhythmias taking the drug digoxin may increase the risk of dying by more than 20 percent.
Answer:
Continents looked like they fit together.
Explanation:
The continents as we know them today have formed, millions of years ago, a single continent called pangeia. The first person to propose this theory was Alfred Wegener, a German meteorologist who realized that the continents had very similar contours, which apparently fit together even thousands of miles apart.
