PLEASE HELP ME ASAP! These are my final exams 100 points. An oyster’s growth rate is affected by genetics and by environmental conditions. For example, oysters growing in Maryland’s Chesapeake Bay can reach 7.5 cm (3 in.) in length in three to five years. The same species of oysters growing in the Gulf of Mexico can reach that same length in just one or two years. • Make a hypothesis about how an environmental condition affects the rate at which oysters grow. • Design an experiment that would test the hypothesis.

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
