<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>
A cardio-respiratory training program comprise of activities that increases heart rate and involves muscle groups. It allows the lungs and heart to work more efficiently lowering the risk of coronary and respiratory diseases. The four components of cardio-respiratory training include:
1. Type
2. Frequency
3. Time
4. Intensity
It does not include weight.
Answer: WEIGHT
This process is called Convergent Evolution.

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

<h3>What is genetic engineering?</h3>
Genetic engineering has to do with the procedure by which the genetic composition of an organism is modified. This is often carried out in a laboratory so as to produce new species of an organism or for scientific research purpose. We know that interaction of genes is determined by Mendelian genetics and the patterns of inheritance have been the constant subject of study.
As such, if a Zebrafish have been genetically engineered to glow in the dark, the knowledge that can be gained from this is knowledge about how genes work in vertebrates. We know that fish is an aquatic vertebrate because it possesses back bone as does other vertebrates (presence of vetebral column).
