AP BIOLOGY

Detailed explanation-1: -The cells between your embryonic fingers died in a process called apoptosis, a common form of programmed cell death. In programmed cell death, cells undergo “cellular suicide ” when they receive certain cues.

Detailed explanation-2: -If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off, ” as leaves from a tree).

Detailed explanation-3: -Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer.

Detailed explanation-4: -Apoptosis, or programmed cell death, is a mechanism in embryonic development that occurs naturally in organisms. Apoptosis is a different process from cell necrosis, which is uncontrolled cell death usually after infection or specific trauma.

Detailed explanation-5: -Apoptosis is programmed cell death. Webbed fingers and toes are abnormal conditions, caused by the absence of apoptosis at the 16th week of gestation, that dissolve the tissues between fingers and toes. Apoptosis leads to removal of old cells and their replacement by new cells.
