B. They make their own food, Position 1 because all of those animals would have jaws. B. Cellular Respiration, A. They belong to the same kingdom but different phyla.
B the origin of new matter in the steady state theory???
The correct answer is option B) their DNA sequences.
The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
Answer:
a = 9
Explanation:
5(a + 4) - 6a + 1 = 12
5a + 20 - 6a + 1 = 12
5a - 6a + 20 + 1 = 12
-1a + 21 = 12
-21 -21
--------------------------------
-1a = -9
/-1 /-1
---------------------------------
a = 9
Smaller DNA fragments migrate <u>more quickly</u> and further over a given period of time than larger fragments.
<h3>Gel electrophoresis and DNA fragments</h3>
Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.
Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.
