Which student correctly identified the geological process that formed Himilayan mountains?
ValentinkaMS [17]

Answer:

Student 2 is correct!

Explanation:

The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates. This immense mountain range was formed by tectonic forces and sculpted by weathering and erosion.

Zielflug [23.3K]

Answer and Explanation:

  1. allopatric speciation: occurs when a population becomes isolated by a geographic barrier, becomes a new species as it accumulates changes by natural selection or genetic drift. Also known as <em>geographic speciation.</em>
  2. sympatric speciation: a new species that may arise as mating and gene flow are reduced between populations that share the same area. In other words, a group of people from the same ancestral population that may evolve differently until they no longer interbreed and develop into a entirely different species.
  3. polypoid speciation: mostly commonly occurs in plants, where an accident in cell division results in extra set of chromosomes. This has been a major source of speciation in the angiosperms. Polypoidity increases biodiversity and a it is a source of new genetic material for evolution.
  4. Both allopatric speciation and sympatric speciation depends on the establishment of reproductive barriers, which prevents gene flow between a new species and its parent species. Reproductive barriers may arise due to geographical, behavorial, psychological or genetic differences which may prevent species to breed successfully with related species.
  5. Adaptive radiation: occurs when a species gives rise to many new species after colonizing a region with diverse habitats. It is a rapid increase in a number of species from a single common ancestor.

Anxiety disorders can be genetic or caused by a traumatic life event.
RUDIKE [14]
This is absolutely true.

Almost every single person will have anxiety in their life. The most common way to get it is if any of your family members have it. Let's say you had an embarrassing moment in your life when you were younger. The simplest thing could cause you to have anxiety. Although I'm 100% sure about this, it is confirmed that if you have anxiety before you are the age of 20 years old, it is positive you have a family member that has it as well.
