The answer is C because water moves from an are to low solute concentration to an area of high solute concentration.
Answer:
The correct answer is d. Vertebral column.
Explanation:
The vertebral column (also called the spine or backbone), is the main component of the axial skeleton and supports the upper body. It is made up of numerous bones, called vertebrae. The vertebrae have different shapes depending on where they are in the column, according to their function. In the embryo, the spine has 33 vertebrae, distributed in 5 categories or regions: 7 in the cervical region (neck), 12 in the dorsal region, 5 in the lumbar region (lower back), 5 in the region of the sacrum (basal part of the column), and 4 in the coccygeal region (the end of the column).
Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
Yes the word believe can be in a hypothesis.
