There is 50% probability that their daughter's son will have the disease, because daughter chromosomes are XX , and the X from father will have x- linked disease, now in next generation the son will have XY chromosomes, Y is from father and X will from mother, now mother have two "XX", out of these two one carry x- linked disease, that means 50 percent chances of having disease in son.

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a:________
sweet [91]

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.

  • A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
  • The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
  • The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
  • Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.

PLEASE HELP ME NOW!!!! (NOT FOR BEGINNER)
Semenov [28]

Answer:

1. C.

2. D

3. D.

4. D.

Explanation:

1. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

2. Landslides are geologic phenomena that can happen suddenly or through imperceptively slow downslope movement. ... A "translational" landslide can happen rapidly and result in all of the soil on a hillside being stripped off and filling the area at the bottom of the slope.

3. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.

4. The Uplift of the Colorado Plateau. The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. ... The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down.

<em>Hope this helps! :D</em>

Could a particular form of life survive on the Martian surface
coldgirl [10]
Gizmono
NASA reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: What sorts of life forms could actually live there?

Any life on Mars today is almost certainly microbial, but beyond that, we can’t be sure of anything until we actually dig it up and study it. Still, we can make some educated guesses about the nature of Martian life, by taking a deep dive into some of the weirdest biology on planet
