Answer:
1 community
2population
3ecosystem
4habitat
Explanation:
the classroom is a community because its people of different cultures and race that come together  and be one
all the mice in the classroom are considered a population because population is the number of people in a certain area 
in the third statement there are all forms of organisms hence showing the biodiversity that ecosystems tend to have
the aquarium provides shelter to earthworms proving them with food of which a habitat provides both shelter and food
 
        
             
        
        
        
"Neurons" are the functional unit of the nervous system; it is the specialized cells transmitting nerve impulses
Hope this helps!
        
             
        
        
        
Answer:
Force
Explanation:
Because velocity is quickness of speed and motion is like moevement, force is like the ammount of pressure. This is why the answer is force.
 
        
                    
             
        
        
        
Answer:
100% red kernel color
Explanation:
R_B_ = Red kernel color
R_bb and rrB_ = yellow kernel color
rrbb = white kernel color
True breeding red kernel x true breeding white kernel = RRBB x rrbb
F1 genotype ratio = 100% RrBb
F1 phenotype ratio = 100% red kernel color plant.
<em>The expected phenotype of the F1 plant is 100% red kernel color.</em>

Explanation:
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
