Answer:
The only types of mutations that matter to large-scale evolutionary species are the mutations that can be passed to offspring (Genetic).
Explanation:
If a mutation is passed to offspring, through the generations it will become more and more prevalent...Eventually causing a pretty good dent on a population size. Hope this helps : )!
Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.
Explanation:
Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it. A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure
Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.
<span>This is due to much of the energy that is consumed by lower trophic levels of the food chain/food web being used at that lower level. This energy is stored or used and, therefore, unavailable to the organisms higher up in the chain. As the chain lengthens, less energy is available, usually as a factor of 10 (1/10 of the energy taken in by the level below the consumer is available to the consumer's level, for example).</span>
