This picture shows the United States Arctic National Wildlife Refuge, a large portion of Alaska
that is protected from human activities that would affect living things in the area as well as

, Read the following information from a Material Safety Data Sheet (MSDS) about the chemical
hydrochloric acid (HCl).
"Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Thoroughly clean shoes before reuse. Get medical attention immediately."
Based on this information, which is the most important thing to do right away if a student spills
HCl on his shirt? - ✔✔Remove the shirt and rinse the skin with water in case the HCl soaked

A lab experiment to determine the rate of ATP production and its use in plants is conducted. In
the lab, twenty circles cut from plant leaves are placed in a container of water with a light
source, which allows photosynthesis to occur. When the rate of ATP production exceeds the
ATP use, oxygen is given off by the plant cells, causing the leaf circles to float.

Using the graph of data from this experiment, at which point was the light source most likely
removed? - ✔✔C
Which component is affected when a catalyst is added to a chemical reaction? - ✔✔the

✔✔TAGCCG
Which blood type could be given as a transfusion for patient with AB blood when the RH factor
is unknown? - ✔✔AB-
