Answer:
Explanation:A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
D. Mutations will always impact an individual on some level
Most of these seem accurate or at least close to being accurate on how mutations affect genes however, some mutations won’t always impact an individual because some mutations are so minor. But this is my best guess
Answer:
When energy flows out of a system, it must all flow into the surroundings.
When energy flows out of a system, ΔEsystem is negative.
When energy flows into the surroundings, ΔEsurroundings is positive.
Therefore,
─ ΔEsystem= ΔEsurroundings
Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.
Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.
