Answer:
survival of fit individuals
Explanation:
I believe its survival of fit individuals because the animals with different horns are going to be able to find a mate or provide better depending on their horn and its kind of like natural selection in the sense those who have genetically better (??) horns are more likely to survive. Hope it helps but it might be a little bit of a confusing explanation.
The organs in the alimentary canal are important to digestion because they work together to move food and waste through the body. Without them, food wouldn't be able to move to their correct organs to digest and provide nutrients & energy, and waste would not be able to get out of the body.

The numbers in front of the formulas
Answer:
Explanation:
Heat can transfer between objects in two different ways. Generally, heat will travel from places of higher heat to places of lower heat.
The first is conduction. This is when the object being heated and releasing heat are in direct contact. Not as much heat is lost in this process, since the thermal energy has nowhere else to go except for the object it is touching. An example would be putting a kettle on a hot stove, but it could also be grabbing a cold pole with your relatively warm hands.
The second is convection. This is where heat is radiated into the air, and thus, transferred by the air, to another object. The actual heat that you feel is actually electromagnetic waves, and its transfer from an object is called electromagnetic radiation. Convection is the heat you feel from a near fire or a space heater. This is also why wind is present in our atmosphere.
There is also radiation. This is caused from the burning or breaking down of a substance. This might come from the sun.
I hope I did enough to deserve the 45 points!
