Answer:
Neurons and muscle cells perform different functions, however they have the same DNA (genetic material) contained within them.
The function of muscle cells is to mechanically contact to allow the body to move in space.
The function of nerve cells is to send and receive signals. in order to trigger an event or elicit a response.
Explanation:
There are two main theories for the lack of organic material in desert soils. Firstly, the organic life in most deserts is so sparse that it cannot produce much organic matter. Secondly when things do die and decompose in the desert the heat and sunlight often bleach nutrients out of the matter before it is decomposes enough to be absorbed into soil
Antibiotics can do more harm than good when it comes to the flu.
A numerical expression includes numbers and operations, so if youre wanting a numerical expression for the number 20, all you have to do is add, subtract, multiply, or divide numbers to equal that.
For example, 5+15=20, 4*5=20, 80/4=20, 29-9=20
The equation for density is:
where the mass is in grams and the volume is in 
.
We are given 4,000 kilograms, and we know that there are 1,000 grams in 1 kilogram, so we need to multiply to convert to grams:
We are also given 0.5 
, and we need to convert to . We know that there are 100 cm in 1 m, and since we are talking about cubic volume, we must also raise 100 to the 3rd power: 
. So now we know that there are 1,000,000 in 1 . We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:
So now that we have the correct units, let's plug them into the equation:
So now we know that the density is 8g/cubic centimeter.
