Independent variable, because it is not dependent on the other variables, because the researcher manipulates that variable and decides how much each mouse gets.
Answer:
The answer is C.
Explanation:
The sympathetic nervous system (SNS). it is predominant in dangerous situations.
It provokes the appropriate actions for rapid response such as: increased heart rate, dilated bronchi to promote the entry and exit of gases, increased sweating, decreased intestinal peristalsis to decrease the energy invested in digestion, vasoconstriction of the arteries, dilation of the pupils so that more light enters, etc.
For this reason axons quickly send a response to all these organs through the sympathetic nervous system.
A membrane that lets only some things pass through it.
<span>The Rock Cycle is the process in which rocks are
formed, changed, and broken down. An igneous rock can either change into a
sedimentary or into a metamorphic rock; just the same that a sedimentary rock
can change into an igneous rock or metamorphic rock. Factors like heat, water,
and air can break and
form new types of rocks in a continuous cycle. <span>
<span>The rock
cycle never stops; it is a continuous process that occurs through time. A
mountain that is composed of<span> metamorphic rocks can easily be
washed away by streams and new sedimentary rocks can be formed through this
process. </span></span></span></span>
