Explanation:
Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.
Mutations that cause the altered codon to produce an amino acid with similar functionality (e.g. a mutation producing leucine instead of isoleucine) are often classified as silent; if the properties of the amino acid are conserved, this mutation does not usually significantly affect protein function.
Answer:
The correct answer is "Provisioning services are disrupted by increased combustion of fossil fuels, which leads to an increase in air pollution".
Explanation:
The ecosystem provides several services that if used with responsibility, could be sustained by the nature. Unfortunately, disruption of an ecosystem service could happen by an anthropogenic activity, which are the activities that humans perform. One example is the disruption of provisioning services by increased combustion of fossil fuels, which leads to an increase in air pollution. The ecosystem provides clean air that gives oxygen for people and animals to breath, however high combustion of fossil fuels could disrupt this service.
Answer:
Our cells are not poisoned to death because it is metabolized by our organs.
Explanation:
- Toxins are any chemical products that damages the functioning of our body.
- To be more specific, human body do not produce any toxins. They only discrete the waste materials that are easily secreted by our body through the metabolic activities.
- Organs like liver and kidneys are responsible for fighting against the harmful waste products and toxins by throwing it out from our body.
