Sedimentary rocks are formedwhen sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rockinto loose material in a source area.
The correct answer is "transport proteins within the cell membrane pick up and release the minerals across the membrane".
Sodium and potassium travel in and out of cells with the help of sodium-potassium adenosine triphosphatase (or Na+/K+ ATPase). This is a transmembrane ATPase, meaning that it is an enzyme located in the cellular membrane of all animal cells. It works as a pump, by pumping sodium out of the cells while pumping potassium out of the cells.
Since one of the dogs is a heterozygous dog, it means that the dog isn’t completely have black fur. Yes, the dog has the gene, but he also has the recessive gene of yellow fur. Making his yellow fur gene be recessive and get covered by the black fur dominant gene. (Bb). With the other parent has pure yellow fur recessive gene (bb). The punnet square below explains more clearly what I mean.
This means that there is a 50/50 chance of getting some puppies with full yellow fur but there is another 50/50 chance of then having the dominant gene of black fur but still having the yellow fur gene hidden.
