I think that having an extra chromosome 21 is tolerable to the point that someone with this condition can survive to maturity because it does not replicate.
There should only be a pair of chromosome 21. In the event that there are 3 chromosome 21, the person that has this extra chromosome has Down syndrome. Changes in the number and structure of this chromosome may result to delayed development, intellectual disability, but not immediate death.
.Answer:
Option A, fix nitrogen inside nodules on the roots of legumes
Explanation:
Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.
Rhizobium or Bradyrhizobium is a gram negative bacteria that satisfies the nitrogen starvation of host plant.
These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.
Hence, option A is correct
Thus, option A is correct
Answer:
The correct answer is c. Fatty acids
Explanation:
There are four major types of macromolecules present in nature and that are carbohydrates(polysaccharides), proteins, lipids, and nucleic acids. These macromolecules are polymers and are made up of monomer units.
The monomeric unit of polysaccharides is mainly glucose, of protein is amino acids, of nucleic acid is nucleotides and the monomeric unit of lipid is fatty acids. Ribosomes are macromolecules because it is made up of RNA and proteins.
So fatty acid is a monomer which joins together to form large macromolecules like lipids. Fatty acids are made up of a hydrocarbon chain which have one attached COOH group at the terminal position.
Therefore the correct answer is c. Fatty acids.
