The idea that organisms more well equipped for their environment tend to survive longer
The idea that organisms more well equipped for their environment tend to not survive
None.
Lysosome
creates energy (ATP) from food; site of cellular respiration
stores food, water, or wastes with the cell; plant cells have a special vacuole
uses enzymes to digest bacteria, viruses, and old organelles (old cell parts are recycled)
create special structures called spindle fibers that are used in cell division
Vacuole
creates energy (ATP) from food; site of cellular respiration
stores food, water, or wastes with the cell; plant cells have a special vacuole
uses enzymes to digest bacteria, viruses, and old organelles (old cell parts are recycled)
create special structures called spindle fibers that are used in cell division
Mitochondria

The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
Which male is the father of the child?
Male 1
Male 2
