Given that,
Density of the liquid, d = 3 g/ml
Volume, V = 20 mL
To find,
The mass of the liquid.
Solution,
The density of an object is given by its mass divided by volume such that,
d = m/V
m is mass
m = d×V
Put all the values,
m = 3 g/mL × 20 mL
= 60 grams
Hence, the mass of a liquid is 60 grams.
Answer: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Explanation: Atoms consist of three basic particles: protons, electrons, and neurons.
During the Quaternary Glaciation, ice sheets expanded, notably from out of Antarctica and Greenland.
The answer is D. -Antarctica
<span>The best describes the first reaction the neuron has is </span>Ions flow into the neuron.
When a neuron sense a stimulus, it will open ion canal and allow ion to flow into neuron causing a change in membrane potential. This will activate a cascade of reaction which needed to sent message to other neurons.
