I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
The answer is hydrogen bonds
Answer:
Both speed and mass causes the kinetic energy to change.
Explanation:
The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)
The relation between the mass, speed of the object can be represented as
Kinetic energy$=\frac{1}{2} m \times v^{2}$
Thus when there is a increase in the mass and speed, the kinetic energy will also increase
Answer:
food molecules into thermal and kinetic energy
Explanation:
The energy held in food is called chemical energy. It is a form
of potential energy held within chemical bonds between
atoms. When the chemical energy in food is transferred to cells
in the body, the energy can be transformed into energy used by
the body to do many things like run, ride a bike, do the dishes,
pump the heart, and keep the body warm.
