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>

Talja [164]

The correct answer is: a. n+1, n+1, n-1, n-1

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis  or meiosis. There are three forms of nondisjunction:  

1. failure of a pair of homologous chromosomes to separate in meiosis I ,  

2. failure of sister chromatids to separate during meiosis II, and  

3. failure of sister chromatids to separate during mitosis.

As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
