A normal human pregnancy lasts forty weeks, divided into 3 trimesters. Which is a key event during the first trimester of pregnancy?The embryo is forming all its major structures and is most sensitive to alcohol and drugsO Most organ systems are fully developed and functionalThe lungs develop and the head points down toward the cervixO The gender of the fetus can be determined without studying the chromosomes CellMitochondriaMitochondrial DNAWhich of the following statements correctly explains the function of the Mitochondria within a cell?The Mitochondria breaks down molecules that are not needed within the cell and returns some of the products of digestion to the cell for use in building new cell partsThe Mitochondria prepares new macromolecules such as fats and lipids by sorting and encasing them before sending them to the correct destination within a cellThe Mitochondria contains most of the genetic material within the cell and is responsible for gene expression and DNA replication when the cell dividesO The mitochondria uses oxygen to convert sugar into chemical energy and controls the metabolism of the cell in a process known as cellular respiration.
