How do plants overcome the force of gravity and move water to their upper tissues? Scientists call the explanation for how water moves through plants the cohesion-tension theory. As water evaporates through the stomata in the leaves (or any part of the plant exposed to air), it creates a negative pressure (also called tension or […]

What pressure is created by the presence of plasma proteins in the blood such as albumin? The osmotic pressure created by plasma proteins is called the colloid osmotic pressure, named to differentiate it from the osmotic pressure across the cell membrane. The concentration of proteins in the plasma is 7.5 gm/dl and in the interstitial […]

Is yellow dominant or recessive? Just because yellow is dominant, it would not become more common over time. Imagine that we started out with our two Yy plants: If we break things apart, we can say that this population has two Y versions and two y versions. Are green seeds dominant or recessive?

Where does the DNA strand split into two for DNA replication? During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of […]

What are the differences between an animal cell and a plant cell? A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply […]
