A response from the amigdala. The reason for this is that when the medulla starts signalling brain regions that are in upper parts, especially the amigdala, this then triggers the fear response (amigdala is responsible for this) which in turn alerts us on a conscious level that we should leave this room for example and go to somewhere where more oxygen is present.
Answer:
D: It is based on facts.
Explanation:
The reason is because science is based off of data and analsys which
Answer:
B, A fossil found in rocks from one time period
Explanation:
Fossils are used to determine the ages of rock layers. Index fossils are the most useful for this. Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in. Hope that this helps you :)
Answer:
Denaturation process: The DNA template
Annealing process: Primers
Elongation process: dNTPs and Taq polymerase
Explanation:
For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.
I hope this clarify you inquiry.
