Answer: position of the carbonyl carbon
Explanation:
In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.
Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.
But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.
In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.
In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon

Examples of echinoderms: starfish, sea urchin, feather stars and sea cucumbers.
Electrical signals are relayed from the retina to the brain
This is an example of Codominance inheritance
<u>Explanation:</u>
A correlation among pair of variants of a gene is termed as Codominance. Unit version of a gene is obtained by individual, designated an allele, from all parent. The ruling allele will be revealed,when the alleles are varied. They are screened if they are the outcome of the additional allele, termed recessive.
The appearance of the a allele is not disguised by another allele is the concept of Codominance . When specifying alleles for codominance, the code is to practice a standard character to express dominant and recessive and do superscripts to describe the various codominant alleles.
