In ocean waves, water particles move ________ and energy moves ________. A) vertically; in circles B) in circles; horizontally C
son4ous [18]
In ocean waves, water particles move in circles and energy moves horizontally. Ocean waves are orbital progressive waves. The water molecules that make up the wave move in circles, or orbits, as the wave progresses. The ocean orbital waves get their start when wind blows on the open ocean, A gentle wind doesn't have much of an effect, but the stronger wind becomes the more it pushes against the water. It transfers energy to the water as it makes peaks and whitecaps in the water's surface.

Explain mutations and how they can cause genetic disease
nadya68 [22]
Answer:

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.

Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.


When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.
