A. It’s the thing you change and you’ll measure the E. coli growth
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)
Answer:
1. Wind moves horizontally because of differences in air pressure. These differences in air pressure are a result of __differential______ heating of earth’s atmosphere from the _sun____.
2:This pressure moves from an area of __high___pressure to an area of__low___ pressure, creating the wind.
Explanation:
The sun rays ‘hit’ the earth's surface with increased obliquity with increasing latitude. In addition, the density of the sun rays per sq meter also decreases with increasing latitude. This is all due to the spherical nature of the earth.
However, there are also local differences that cause the earth's surface to heat differentially such as terrain and cloud cover, etc. This creates regions of warmer air mass (low-pressure zones) and cooler air mass(high-pressure zones). These differences cause winds because of air rushes from high to low-pressure zones due to differences in air masses’ temperature-related densities.

Answer:
The correct answer is: c) the heart rate slowed and eventually stopped.
Explanation:
The vagus nerve (X) is a cranial nerve with the function to parasympathetically <u>innervate the heart, the lungs and the digestive tract. </u>
As a part of the Autonomic Nervous System (ANS), the vagus nerve regulates things such as heart rate and gastrointestinal peristalsis (things we cannot control).
Given that it is a component of the parasympathetic division of the ANS, it stimulates the organs when the individual is performing normal activities like <u>resting and feeding</u> (unlike the sympathetic division, responsible for the fight-or-flight response). For this specific reason, the vagus nerve slows the heart rate, so if it were to be stimulated in a frog, it would produce the same thing and ultimately lead to its heart stopping.
