A student conducts an experiment with an electromagnet made out of coiled wire. He sees how many paper clips the electromagnet is able to pick up. The table shows the data collected.

Based on this data, what conclusion can the student make?

A. A higher electric current leads to a weaker magnetic field.

B. A higher electric current leads to a stronger magnetic field.

C. A greater number of wire turns to a weaker magnetic field.
D. A greater number of wire turns leads to a stronger magnetic field.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
