Similarities:
Both involve ion movement. Both use ion channels to move ions across the cell membrane, in or out of the cell.
Differences:
Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP. Active Transport uses an ion pump (or Sodium/Potassium pump) to move 3 sodium ions out of the cell and 2 potassium ions in to the cell through the energy of 1 ATP molecule.
In active transport particles move against a concentration gradient and therefore require energy which must be supplied by the cell. Carrier proteins that are found in the cell membrane of cells use energy to transport molecules or ions across the membrane, against the concentration gradient.
Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.
Answer:
Lava is rock that has undergone a physical change and has liquefied. What is known about this change? The lava gained mass
Explanation:
The low salt diet is a great solution to overcome heath determinant of Biology and genetics.
- According to this question, Patel and her siblings have inherited high blood pressure from their parents. This tells us that the health condition is a genetic disorder, which is branch of Biology.
- Patel and her siblings are however, on a low salt diet as a solution to overcome the health challenge (high blood pressure).
This solution is, hence, a great solution to overcome the heath determinant of Biology and genetics.

The ovaries are a physical structure and the function of the ovary is to produce eggs in the birds.
<h3>Physical structures of birds</h3>
The physical structures are those structure that we can see in an organism but externally and internally. The table is not shown here but we can still make some corrections.

Sea otters affected biodiversity because they control the
populations of sea urchins, which endanger kelp forests. Kelp
forests are important because they convert sunlight to living material, and
they also provide food and habitat to sea creatures. Kelp is important in
sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable
for the large size of abalones in California.
