Answer:
Right handed,right handed,positive,left handed, negative,negative
Explanation:
In a circular bacterial chromosome the structure of DNA is a right handed double helix.
if DNA is twisted in the right handed direction,it becomes overwound. overwinding results in positive supercoiling.
If the DNA is twisted in the left handed direction it becomes underwound. Underwinding result negative supercoiling.
one effect of negative supercoiling in bacterial chromosome is to promote separation of the two strands of DNA in the double helix.
Answer:
lots of carbon dioxide and cold temperatures
Explanation:
<em>Calcium carbonate has low solubility at room temperature and the solubility increases as the temperature decreases. The solubility of calcium carbonate also increases in water with high level of carbon dioxide due to the formation of more soluble bicarbonate. </em>
<em>
</em>
<em>This is why carbon dioxide rich rainwater is able to erode limestone rocks, leading to the formation of caves, stalactites and other structures in the long run as a result of reversal of the process.</em>

Answer:
Essentially mRNA acts as the middle man between genetic information in DNA and the amino acid sequence of proteins.
Explanation:
messenger RNA has codons that are complementary to the sequence of nucleotides on the template DNA, which the mRNA is translating. These codons then direct the formation of amino acids through the action of ribosomes and tRNA to create proteins based on the specific DNA code translated.
Answer:
D
Explanation:
Linoleic acid is an omega-6 fatty acid that is composed of an 18 carbon chain polymer. Most of the bonds are single bonds but few are double bonds. The double bonds form ‘kinks’ (bends) in the chains. The more the C=C bonds the more bendy the molecule. Nonetheless, it is significant to note that single (sigma) bonds are easy to rotate around their axis than double and triple (pi) bonds. The more the single bonds, the more flexibility the the molecule.
