Answer: Amount of sunlight absorbed
Explanation:
The amount of sunlight absorbed by the body affect the color of the individual. Rest all the factors that affects the color of the individual are genetic factors.
The person who absorbs more sunlight will have more melanin concentration or amount in their cells as as compared to the person who absorbs less sunlight.
Hence, the correct answer is option sunlight absorbed.
Explanation:
Many invertebrate animals cant survive in water that has been polluted and resulted in a lowering of oxygen concentration so the presence or absence indicates the extent to which a body of water is polluted.
Lichens can be used to indicate air pollution as they grow exposed to places such us rocks and tree barks. They need to be efficient at absorbing water and nutrients to grow there. Rain water contains enough nutrients to keep them alive. Air pollutants dissolve in rain water especially sulfur dioxide can damage lichens and prevent them from growing. This makes them a natural indicator of air pollution.
Answer:
The scientist must complete the experiment, evaluate the results and disclose his conclusions.
Explanation:
If the scientist wishes to find conflicting data in a widely accepted theory, he must first establish a scientific experiment using all the steps of the scientific method. It is important for the scientist to complete the entire experiment so that he can evaluate the results and reach concrete conclusions about whether there is, in fact, conflicting data in the theory. The results should generate conclusions that must be disclosed regardless of whether the cinetist's hypotheses are proven or not.
The scientific method is a set of rules that guide the execution of a scientific experiment.
Answer:
Thermostability
Explanation:
Thermus aquaticus is a species of bacteria that can tolerate extremly high temperatures and it is the source of the heat-resistant enzyme Taq DNA polymerase used in PCR. The advantages of this enzyme are its thermostabilty (temperature optimum 80°C) so it doesn't have to be added after every cycle of thermal denaturation of the DNA and also that it can be isolated in a pure form.
