Pls help and pls don't waste my points 1. What data did the tests on the purified substance produce? How did this data further support the hypothesis that DNA is the transforming factor?

2. Procedure

Description of Evidence

Transformation Test

Purification Procedure

Identification Tests

3. What data did the purification stage produce? How did this data help identify the transforming substance?

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

he is very short, and he can only reach halfway up on the elevator buttons. but on a rainy day, he has his umbrella with him, and he uses it to poke the button at the top.

explanation:

i was told this before by a teacher, so yeah

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
