Answer:

D

Explanation:

This is caused mainly by nondisjunction of the sex chromosomes in gametes during meiosis. Therefore a gamete will have both XX chromosomes and fuse with a normal one with Y during fertilization. An XY gamete can also fuse with a normal one with X chromosome. These males with Klinefelter's syndrome produce less than normal levels of testosterone.

Typically when we think about extreme weather, we think about the effect of weather on humans and other life forms. However, weather events also greatly impact non-living things. Freeze and thaw cycles tend to break up rocks, weathering them physically. Landscape erosion can be greatly enhanced by storms because rivers and streams are able to transport larger amounts and larger sizes of material than they otherwise would, due to faster flow velocities. Sand at beaches is carried away by strong storms until it can be replenished over time. Sediments become hydrated during rainfall events, which can result in landslides and land movement. Many of these processes can create hazards for humans, but the physical landscape is very much shaped by extreme weather events. Weather is weather, which is nonliving. Erosion is affected by weather, the more rain there is, the more erosion. The more temperatures change, the more erosion because things swell as they warm up and shrink as they cool off, which can cause them to break.


Hurricane affects come from both wind and water impacts. Wind and waves break coral, damaging it or forcing it on shore and disrupting the ocean ecosystem. Fish and benthic organisms face turbulent conditions due to waves and wind. ... Winds dislocate sea and migratory birds caught in the eye of the storm.


Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes. Living things are defined by a set of characteristics including the ability to reproduce, grow, move, breathe, adapt or respond to their environment. Extreme heat causes lakes and rivers to dry up. Some kinds of earth can also dry up so much that it gets cracked.

Extreme rainfall causes floods and landslides.

Extreme cold can cause rocks to break, when the water that leaked into cracks in the rock freezes and expands.

If I knew more about the water cycle, I might be able to tell you more about how extreme weather affects clouds and other parts of the water cycle.

Which of the following would be LEAST likely in the fossil record? Which of the following would be LEAST likely in the fossil re
GREYUIT [131]

Answer:

The correct answer is desert-dwelling species.

Explanation:

Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.  

For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.  

On the other hand, places like deserts would be the least likely to have a fossil record as deserts are devoid of optimum conditions required for the formation of fossils. In places like a desert, decomposition and demineralization of the components like bones take place at a brisk rate.
