DNA collecting samples helping species recover often depend, which can reveal valuable information about details ranging from inbreeding and population history to natural selection.
To measure the genetic diversity of particular gene, scientist look at how many different versions of it are present in a population.Use of molecular marker for identification of endangered species offer promise of conservation biology.
Conservation genetics is the application of genetics to understanding the decreasing population and species extincts.By effective managing these ecosystem we can help preserve threatens and endangered. It helps in determine evolutionary context of endangered species and enables the development of better management and strategies for endangered species.

Organisms depend on buffer that are compounds that stabilize pH by absorbing or releasing h ions. It consists of weak acids and weak bases.
The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.
The nucleic acids must have positive charge that helps in formation of double helices.
Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.

Answer:
The triceps muscle extends when the biceps muscle is contracted.
Explanation:
The biceps and triceps muscles,work together in creating functional movement. These movements contribute to the ability to perform day to day tasks.
These muscles function in flexing and extending the arm. <em>Biceps for flexion</em> and<em> triceps for extension</em>. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the <em>primary mover</em> while the other muscle, is the <em>antagonist</em>. These muscles work in opposite direction, aiding the movement of the arm in both directions.
When biceps are contracted, the triceps are extended. Their antagonistic nature is beneficial because both muscles set the motion patterns at particular points. If we only had biceps extension of the elbow will be impossible and any movement that requires extension would not have been possible and vice versa.
They are anti-parallel. There is a 5' and 3' direction. Each of these must line up with the opposite. 5' with 3' and 3' with 5'.
