Answer:

Horses

Explanation:

Between the mouth and stomach of all mammals, there is a tube called the esophagus. When the esophagus enters the stomach, it is surrounded by a muscle which allows all mammals to keep food inside, but if necessary, it relaxes to return the food as rumination (in the case of cows) or as vomit (for example in dogs, cats, humans); but on the horse that muscle is so strong that it is impossible for food to return, so they can’t vomit, and they cannot burp either.

For horses, having that muscle so developed is a great inconvenience, since vomiting is a defense system of the body that seeks to eliminate something that is not in good condition in the stomach.

How do molecules of a polar compound differ from those of a nonpolar compound?

Sergio039 [100]

Covalent bond = a bond in which the electrons are shared by the partner atoms.

Polar bond = simply a type of covalent bond in which the electrons are 
shared but not equally. This happens when two different atoms come 
together, such a C and O. Each atom has a different ability to draw 
electrons to itself when it shares electrons (that drawing ability is 
called Electronegativity).

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the

dedylja [7]

Area circle = π*r²

Area square = l²

The side of the square is equal to the diameter of the circle

Area square = D²

A diameter is always twice the radius

Area square = (2r)² = 2²r² = 4r²

So this is the rate:

Area circle/Area square = (π*r²)/(4r²)

Area circle/Area square = π/4

Volume is always Area*h when cross sectional area is a constant

Volume Prism = Area Square*h

Volume Prism = 4r²*h

Volume Cylinder = Area Circle*h

Volume Cylinder = π*r²*h

So far this is option D)

Let’s calculate the rate:

Volume Cylinder/Volume Prism = π*r²*h/4r²*h

Volume Cylinder/Volume Prism = π/4

Volume Cylinder = π/4* Volume Prism

This is also option D)

Now let’s calculate Volume Cylinder from that formula:

Volume Cylinder = π/4* Volume Prism

Volume Cylinder = π/4 *(4r²*h)

This is also option D)

So option D) is correct

Nimfa-mama [501]

This would be an isotonic solution. If a cell is placed in a solution of salt with the same concentration of salt in the cell, nothing will happen. The water level will stay the same.
