The most superior part of the spinal cord is the foramen
magnum. This is considered to be the largest foramen in an individual’s skull
and that it is also responsible for having to connect or link the brain and the
spinal cord.
External and internal cues trigger different genes to turn on and off in different cells
Answer:
The answer to these questions are the following:
1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter
2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter
Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:
1. In a hypotonic solution, the cells will become turgid
2. In an isotonic solution, the cells will become flaccid.
3. In a hypertonic solution, the cells will shrink (plasmolysis)
When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss
When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.

Answer: body systems that can directly impact fluid balance includes:
b)urinary system
c)respiratory system
f)sweat glands.
The correct option is B, C and F.
Explanation:
Homeostasis is the mechanism by which the body maintains a steady ( constant) internal physical and chemical conditions. The following variables needs to be kept in equilibrium for optimal functioning of the body system. They includes: the body temperature, fluid balance, blood sugar levels. These variables are in turn controlled by one or more regulatory systems which includes;
- urinary system:when blood volume gets too low or blood electrolytes get too concentrated, the kidneys can retain water thereby decreasing urine output. When blood volume or pressure is too high, the kidneys can excrete more water thereby increasing urine output.
- sweat glands: this regulates both fluid and temperature.
