Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
Answer:
Friday to Predator??
Explanation:
Do you mean Prey to Predator, if so, On average, 90% of an organism's energy is used for its life processes and only 10% is passed on to its predator in the next trophic level. There are rarely more that 4 or 5 trophic levels in a food web.
First option:
Ecosystem --> population —> community —> organism
Answer: Marginal analysis
Explanation:
Marginal analysis is used to evaluate the marginal benefits and marginal costs of reducing pollution.
As the complexity of environmental protection grows, inexpensive and simple ways of mitigating emissions start to decrease, and more costly approaches need to be used and the marginal cost is increasing. Often, marginal benefits are reduced as environmental security increases.
As the amount of protection for the environment rises to, the marginal costs outweigh the marginal benefits. Society is not allocating resources effectively at this stage of environmental security, since so many resources are giving up to reduce emissions.
As the scope of the environmental regulation grows, additional environmental spending will likely result in increased marginal costs.
Hence, marginal analysis is a specific tool used to way the cost of benefit versus cleanup in the environment.
The answer is thermal energy.
