Answer: The correct answer is A). Is mostly lipid while the whole cell is mostly aqueous .
This is because the cell membrane is majorly composed of the phospholipid bilayer. It is a protective covering present in all the cells.
On the other hand, the whole cell other than the cell membrane is mostly aqueous. It contains 80% of water, therefore considered as aqueous. It is also referred to as cytoplasm of the cell. Most of the cellular activity including metabolic processes and signaling pathways occur within the cytoplasm of the cell.
The composition of a cell differs from that of the cell membrane in that the cell membrane is mostly lipid while the whole cell is mostly aqueous.
Further Explanation:
Cell is surrounded by the cell membrane made up of lipid bilayer. The fluid mosaic model states that the cell membrane is made up of two layers of lipid and the proteins present externally, internally and in the transmembrane.
The lipid molecules are amphipathic having polar head and non-polar tail. The fatty acid present in the lipid may be saturated or unsaturated. Saturated fatty acid has presence of single bond while unsaturated one has double or triple bond present in them.
The protein present in the lipid bilayer can act as the channel molecule or receptor molecules.
The cell contains various cell organelles such as nucleus, mitochondria, chloroplast, ribosome, endoplasmic reticulum, Golgi bodies. Mostly the cell contains fluid inside it called as cytoplasm. The cell organelles are suspended in the aqueous solution of the cytoplasm. Various chemical reactions occurs in the cytoplasm of the cell.

Answer: The correct answer is - The ratios of Thymine and Adenine were similar, as were the ratios of Guanine and Cytosine.
According to the Chargaff's rule, in a DNA molecule, the amount of Guanine (G) is equal to the amount of Cytosine (C) and the amount of Adenine (A) is equal to the amount of Thymine (T).
This is because A pairs with T and G pairs with C.
This means that the ratio of T and A are similar, as are the ratio of G and C.

AIDs and the bubonic plague are examples of a pandemic.
The word pandemic is from the Greek word pandemos which means pertaining to all people. The word "pan" means all and the word "demos" means people.
A Pandemic is said to be a disease outbreak of global proportions. It usually caused by the emergence of a new or novel virus among humans. It is easily transmissible and causes serious illness.
The bubonic plague, called the black death was the worst pandemic in history killing 75 million people.
the answer would be pandemic a wide spread diese

b. semi-permeable
c. lack of compartmentalization
d embedded proteins
Answer:
lipidbilayer
Explanation:
The unpredicted changes in the genetic material of chromosomes in a cell is known as Mutation. Mutations are the changes in gene caused by mutagens. Thus, the correct option is A.
Mutation can be defined as any change in the DNA sequence of a cell. These may be caused by mistakes during the cell division, or may be caused by exposure to DNA-damaging agents in the environment which are called Mutagens. Mutations can be harmful, beneficial, or have no effect.
Mutations can affect an organism by changing the phenotype or it can impact the way DNA of an organism codes the genetic information. When mutations occur in an organism they can cause termination of an organism or can be partially lethal.
Therefore, the correct option is A.
