Answer: 100%

Explanation:

if the mutation presents autosomal dominant inheritance, each affected individual will show 100% alteration in the protein, thus , being dominant, it is considered that the disease pattern will predominate even if it has genes that do not express it since these will be recessive and canceled by the dominant ones.

The ocean is the largest reservoir of carbon on Earth. Which of the following would most likely store carbon for the longest amo
Leviafan [203]

Answer: Calcium carbonate shells of marine organisms, like coral, oysters, and clams.

Explanation:

Carbon dioxide in the gaseous form is absorbed from the atmosphere into the oceanic waters. The carbon dioxide is generated due to human activity like burning of fossil fuels, deforestation, and by other activities. This increases the acidity of the oceanic waters, it affects the reef building in animals. The animals use the carbon dioxide to produce calcium carbonate structures that are used for building up the coral reefs and exoskeleton like shells of oysters and clams. This way carbon dioxide become an important component in the structure of the living organisms in the ocean. This way carbon dioxide get stored in the structures of marine organisms being the largest reservoir of carbon dioxide.

Answer:

Here's an explanation instead:

Explanation:

ALL STARS BEGIN IN A STELLAR NEBULA / NEBULA

Depending on how much mass the star has, it changes what path of life cycle it will take. Low mass or average mass stars become an average star, also called a main sequence star. It swells after millions of years into a Red Giant which is GIANT. Many many many years later, it becomes a planetary nebula, and finally becomes into a white dwarf.

If the star has a large mass, it is classified as a massive star, and also goes through a form of main sequence. It swells into a MASSIVE GIANT TREMENDIOUSLY LARGE AND UNNECCESSARILY BIGGO star called Red Supergiants. After millions and billions of years, it becomes a Supernova, which finally becomes a black hole if the outer layers literally get blown off into space and the core collapses and gets compacted into incredibly dense Nano-Googleplex  sized molecules. If it doesn't, it becomes a cool Neutron Star.

I cannot drag tiles around, because there is no tiles or labels, however, I hope you get the point from this weird answer.
