Here is the answer of the given question above.
Often times, non-human life in an urban ecosystem is more disturbed in a way that changes happen rapidly, such as the soil and plant cover and temperature and water availability. In this kind of ecosystem, there is no stability and sustainability. On the other hand, in an undeveloped forest ecosystem, plants play a major role and that, the lives in this kind of ecosystem is undisturbed, making it more ideal for many animals to live. Hope this answer helps.
Answer: I can only list one (sorry): saber-toothed cats.
Explanation: . . .
<span>The enzymes are used to cut DNA sequences into smaller pieces. Therefore the answer is D.They break DNA into fragments that vary in size.</span>
The correct answer is: b. It is free to bind to another promoter and begin transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
Answer: "motor unit" .
