Answer:
You should do the sport basketball, as it involves the body systems of the circulatory system and muscular systems.
Explanation:
Analyzing the proteins of the Racoons and lesser pandas, there will be huge similarities with minor modifications.
These species will be very closely related.
<h3><u>Explanation:</u></h3>
The evolutionary background of the species are mainly studied based on the similarities of the nucleotide sequences and proteins. While studying the Lesser pandas and Racoons, there was a huge similarities in then based on their structures, and on their protein composition. The nucleotide sequences also showed huge similarities which also points that they have developed from same ancestor. This is why they are very closely related with each other by means of evolution.
The mesenteric veins and the hepatic portal vein
There is an electrical gradient and there is a concentration gradient.
1.) Chemical gradient better known as concentration gradient is much more powerful and compelling than the electrical gradient.
2.) Water is a polar molecule, meaning one side it positively charged while the other is negatively charged. This polar charged molecule causes water to have a weaker electrical gradient, thus the water has to move on its concentration gradient.
Hello. This question is incomplete. The full question is:
"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment?
"
Answer:
Approximately 29 cycles of PCR would be required.
Explanation:
As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.
PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.
In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:
32 ^ x = 10 ^ 9
x = 28.3 = approximately 29 cycles.
