Identify several reasons why a magnitude 6 earthquake in New Orleans might be more damaging than a magnitude 7 earthquake in San

Francisco.
Biology
1 answer:
MAVERICK [17]3 years ago
8 0

Answer:

San Francisco has a history of earthquakes, while New Orleans has never had one. Because of risk assessment, buildings would be built much more sturdy in San Francisco vs New Orleans. New Orleans is surrounded by water and marsh and the area covered with loose sediment, which would exaggerate the ground movement. Both are densely populated but getting out of New Orleans is difficult (ex-Hurricane Katrina)

Suppose the femur bone of an animal has 1,000 atoms of carbon-14 when the animal dies. How many atoms of carbon 14 will be prese
shtirl [24]

Answer:

After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.

Explanation:

The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.

Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.

In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.

Cystic fibrosis is a genetic disease in humans in which the CFTR protein, which functions as a chloride ion channel, is missing
KiRa [710]

Answer:

ABC transporter protein

Explanation:

ABC transporter protein refers to the ATP binding cassette protein which utilizes the AT energy to transport the substrates from one side to another side. The ABC proteins are one of the oldest proteins known in the organisms.

The CFTR protein which acts as a chloride channel in the membrane which transports the chloride ions across the membrane utilizes the ATP energy in the transport.

Thus, ABC transporter protein is correct

Xerophytes minimize water loss by _____. view available hint(s) xerophytes minimize water loss by _____. using the c3 pathway de
Bad White [126]

Answer:

Use the CAM pathway

Explanation:

  • Xerophytes are plants  that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
  • Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
  • Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.
