- An object's kinetic energy depends on its mass and its speed.
- The faster something is moving and the heavier it is, the more work it can do.
- Kinetic energy increases as an object moves faster.
- If an objects speed is doubled > kinetic energy is quadrupled.
<em>If an object is not moving, it does not have kinetic energy. </em>
Answer:The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Explanation:
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
No they cannot. Lol lol lol
