The first and last sounds most reasonable, but I will go with the last one.
<h2>DNA hold an organisms hereditary information.</h2>
Explanation:
- DNA stands for deoxyribonucleic acid.
- DNA contains genes that are specific sequence of nucleotide that code some proteins or other gene products.
- Genes are specific to an organism and carry the hereditary information.
- Genes are responsible for the trait or characteristic of an organism.
- DNA is the bearer of hereditary units for most organisms except in case of some Viruses.
- In viruses RNA holds the hereditary information.
Answer:
Prokaryote/Bacteria.
Explanation:
The features of the cell which is mentioned in this question match with that of prokaryotic organisms like bacteria.
The salient features of a bacteria are mentioned as under:
1) Presence of nucleoid instead of nucleus: Bacteria do not have well defined nucleus like eukaryotes so their chromosomal material is freely scattered in the cytosol.
2) Plasma membrane: They have plasma membrane which surrounds their interior i.e. their cytosol and other organelles.
4) Cell wall: Outside their plasma membrane they have a rigid cell wall made up of peptidoglycan which provides them a specific shape.
3) Ribosomes: They have a lot of ribosomes in their cytosol.
Answer:
Option). They have a double-bonded oxygen in different locations.
Explanation:
Both glucose and fructose are monosaccharides, having molecular formula C₆H₁₂O₆.
Glucose and fructose are different sugars, aldose and ketose respectively, due to the different position of carbonyl group (double bonded oxygen with carbon or C = O group).
In glucose, the oxygen atom makes double bonds with last carbon atom of the chain, which means carbonyl group shows an aldehyde group. Thus, it is an aldose sugar.
In fructose, the oxygen makes double bonds with an internal carbon atom and represents a ketone group. Thus, it is a ketose sugar.
Thus, the correct answer is third option.
