Answer:

speciation occurs

Explanation:

When some organisms from an original population colonize a new habitat and become geographically isolated from the source population, the accumulation of genetic variations leads to reproductive isolation of these two populations.

Over generations, the isolated populations evolve into two separate species as they are unable to interbreed when allowed to do so.

The geographical isolation of two populations of a species followed by the accumulation of genetic variations leads to allopatric speciation.

Explain further the idea that indicates that all of life is related and can be divided into three major clades, often referred t

padilas [110]

All of life can be divided into three major clades because it is believed that all branches of the tree of life have the same evolutionary origin.

<h3>What is evolution?</h3>

Evolution is descendence with modification, which generally is due to the process of natural selection.

Evolution indicates that all organisms derive from an ancestral organism (it is related to the cell theory).

In conclusion, all of life can be divided into three major clades because it is believed that all branches of the tree of life have the same evolutionary origin.

Which diagnostic test is used for the direct visualization of ligaments, menisci, and articular surfaces of joints?

Sati [7]

Arthroscopy is done for direct visualization of the ligaments, menisci, and articular surfaces of the joints. Thus, option A is correct.

<h3>What is the role of ligament?</h3>

Ligaments are type of connective tissue which help to connect bones, joints and organs. It provide support internal parts of the body.

It is made of a band of connective tissue, collagenous fibre and spindle-shaped fibrocytes which is an elastic fibers.

Ligaments holds bones together, stabilize it, provide strength to joints etc.

By the use of Arthroscopy doctors can diagnose and treat the joint’s structural problems like any dysfunction. Hence, Option A is correct.
