You'll want to double check, but I think it's (a) cotyledon.
Living things are made of types of molecules, known as macromolecules.
There are four major classes of biological macromolecules:
carbohydrates
lipids
proteins
nucleic acids
Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
Answer:
The correct answer is d. DNA polymorphism and disease gene are linked.
Explanation:
DNA polymorphism helps to study the difference in nucleotide sequence of one DNA in comparison to the standard one.
DNA polymorphism is an important tool to analyze the disease that is caused due an alteration of gene sequence leading to genetic mutation.
Now the altered gene sequence is compared with the normally functioning gene to draw a statistical relationship between altered gene sequence that causes disease with peviously discovered DNA polymorphism.
