Which organelle triggers the destruction of skin cells responsible for the webbing of skin between the fingers and toes of a developing fetus? cytoplasm
nucleus
vacuole
lysosome

lysosome

Explanation:

Apoptosis is the regulated or controlled death of cells. It is sometimes referred to as "programmed cell death." This occurs when external and internal factors trigger genes to produce "self-destruct" enzymes. These enzymes are thought to come from the lysosomes inside the cell. Our immune system is also involved in absorbing these cell parts and recycling them to make new molecules or cells

When humans are in early fetal development, the fingers and toes are connected by a webbing of skin between them. Later in development, apoptosis takes place whereby enzymes are released from the lysosomes to destroy these skin cells. As a result, when we are born, our fingers and toes are separated. You may know of someone that has not had digital apoptosis happen normally. They may have a couple of toes or fingers webbed together. This is not all that uncommon.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
