Answer: As the change in allele frequency causes the change in genome of the living organism inside few generations.
Explanation: The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.
All cells are enclosed by a plasma membrane that is similar in structure and function. Cells have outer plasma membrane that regulates that is not only what enter in the cell.
Prokaryotes and eukaryotes both cells possess internal membrane that encase their organelles and control the exchange of essential cell components. The endoplasmic reticulum which has the structure similar to that plasma membrane which also considered as the cell membrane.
Yes plasma membrane and cell membrane are same , both are biological membrane which separate the interior of cell from the cells's extracellular space.The cell membrane is the security guard because the membrane controls what goes in and out of a cell like a security guard which control goes in and out of the gate.

Answer:
a) the oxidizing agent.
Explanation:
In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.
Answer:
DNA is known as the genetic material of all the organisms except some viruses. DNA is made of four nitrogenous bases, pentose sugar and the phosphate group.
1. Watson and crick meant that DNA shows the complementary base pairing in which adenine binds with thymine and cytosine binds with guanine. This base pairing has allowed the single DNA stranded to carry the information that are necessary for the synthesis of the complementary daughter strand.
2.The separation of the strand should be done in such a way that friends should get each single strand of DNA. The information stored in the DNA is available in the single strand of DNA.
Answer:
C. Ethanol, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements
Explanation:
Acetobacter must have a sufficient supply of oxygen and cannot grow in its absence. Colonies of acetobacter can be detected by a culture media containing ethanol as carbon source, the acid produce by the bacteria will dissolve the chalk thereby leaving a clear zone around the colony.
