Which of the following statements about water is FALSE? Water carries a dipole because of the geometry of the two oxygen-hydroge
Rudik [331]

Answer:

b. The hydrophobic effect is driven largely by the entropy of the non-polar substance.

Explanation:

The hydrophobic effect is the tendency of nonpolar substances to aggregate when placed in a watery medium. Water has a tendency to form a maximum number of hydrogen bonds with other water molecules or polar substances. When the nonpolar substances are present in water, the water molecule is not able to form the optimum number of hydrogen bonds.

The nonpolar substance orient themselves around the water molecule to allow the formation of hydrogen bonds. This orientation is energetically unfavorable as water molecules are present in a more organized pattern and have lesser entropy that the bulk water. This results in a hydrophobic effect wherein the nonpolar substances exclude water to increase the entropy of water.

What negative effect does sickle-cell disease have on the circulatory system?
Tatiana [17]

Answer:

Because sickled cells restrict blood flow, individuals can periodically experience swelling and extreme pain in any body organ or joint. This can last for hours or weeks. Sometimes permanent damage can occur to organs deprived of oxygen and nutrients

Explanation:

Red blood cells are designed to pick up oxygen in the lungs and transport it throughout the body via the circulatory system. Their donut-like shape and water-balloon-like flexibility allows them to pass through even the tiniest blood vessels.

Sickle cell anemia is a hereditary condition that causes some red blood cells to distort into rigid crescent moon shapes.

Normal red blood cells can flow freely through blood vessels. Sickled cells get stuck in the blood vessels and cause blockages.

What would happen if the Earth was tilted at 45⁰ rather than 23.5⁰?
zysi [14]
If the Earth's axis tilted 45 degrees instead of the current 23.5 degrees, the seasons would be far more pronounced than they are, and the poles would be warmer overall. ... An axial tilt of 45 degrees would bring more heat to bear on the hemisphere facing the sun.

What are foreshocks and aftershocks? *
Pavlova-9 [17]

Answer:

Explanation:

Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 fault lengths distance from the mainshock fault.

Foreshocks are relatively smaller earthquakes that precede the largest earthquake in a series, which is termed the mainshock.
