Which of the following is surrounded by two phospholipid bilayers?
the ribosomes
the vesicles
the cytoplasm
the nucleoplasm

The correct answer will be option-the nucleoplasm.

Explanation:

The nucleoplasm is the nuclear sap which is enveloped or enclosed by the nuclear envelope. The nucleoplasm contains the nucleolus, enzymes and the chromosomes.

The nuclear envelope is made up of two layers of the lipids called the outer and inner membrane which are composed of lipids. The envelope contains the nuclear pore to transport substances like mRNA.

Thus, option-the nucleoplasm is the correct answer.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
