The correct answer is option B
The structure of the sperm is divided into three parts head, body and tail. The head region consists of many enzymes and the tail region of the sperm helps in providing mobility to the sperm.
The structure of tail adds propelling movement by whipping and undulating the sperm. The sperm moves through the reproductive tract to reach the egg.
different chemical reactions can occur in isolation of each other.
Further explanation
cells can be divided into 2 types according to the presence or absence of the cell nucleus membrane. Cells that do not have a nuclear membrane are called prokaryotic cells. Whereas cells that have cell nuclei are called eukaryotic cells. There are theories of biological evolution and the origin of life that explain the origins of prokaryotic and eukaryotic cell formation.
there is a theory that believes that eukaryotic cells are formed from the prokaryotic cell revolution which continues to grow increasingly complex.
actually the origin of life began in the ocean through the formation of organic compunds from simple compounds, then these compounds will continue to develop into more complex compounds. Simple complex compounds that will form a complex called primordial soup or primordial soup.
The formation of genetic material and cell membranes is believed to be two important steps after the formation of primordial soup and before life. The first genetic material and the first enzyme may be RNA.
Protobion develops into complex forms that contain DNA and can use many raw materials from the environment. Protobion will be replaced with organisms that can make the molecules they need (autotrophs).

Arachnids live anywhere they can find food. They live in grass fields and wet swamps. They live in hot, sandy deserts and cool, dark caves. They live in tropical rainforests and on rocky mountaintops. Arachnids like mites and ticks live in the fur of animals.
Arachnids often eat other invertebrates. Arachnids eat other arachnids, insects, small rodents, and even some small birds. Mites and ticks however feed off the blood and tissue of living animals, even humans. Other mites eat from liquified plants, fungus, and other organic materials.
