The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
Answer:
Being careful when making decisions
Explanation:

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.
The correct answer is C. It is so strict because a foreign species could compete with a native species and drive it to extinction.
The Hawaiian islands are one of the geographical isolated islands which faces the problem of the invasive species affecting the biodiversity of the island negatively.
The foreign species is equipped better to survive in the Hawaiian habitat and competes with the native species for the resources and food. The interaction and competition of the foreign species in the Hawaiian environment and habitat limits the resources for native species which increases the chance of the native species getting endangered.
The Hawaii Invasive Species Council along with other bodies such as department of agriculture, department of business and economic development, private and other government and non-government bodies have taken initiatives towards eradication of invasive species by strict laws.
