Meninges are membranes that cover and protect the brain and spinal cord.
There are three layers of meninges: Dura mater (closest to the bone), Arachnoid loosely around the brain, Pia mater is closely attached to the brain and spinal cord surface.
Answer: a. True
Explanation:
Glomerular filtrate is formed by the difference in force of hydrostatic and osmotic pressure. This physical force involves:
Bowman's capsule hydrostatic pressure: This includes the pressure that develops in the Bowman's capsule against the fluid to be filtrated expelled out by the glomerulus.
Glomerular hydrostatic pressure: The glomerulus is the main site of production of filtrate. It is higher than the average blood capillary hydrostatic pressure. It allows the water and solute molecules to be filtrated out of the plasma membrane.
Colloid osmotic pressure: The osmotic pressure which is generated by the large molecules is the colloid osmotic pressure. It is created by the plasma proteins. This pressure draws water from the glomerulus.
Answer:
- Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment.
- Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
- Clumped dispersions may also result from habitat heterogeneity. If favorable conditions are localized, organisms will tend to clump around those, such as lions around a watering hole.

Answer:
increased pressure difference between her feet and her head. Lying horizontally reduces the pressure difference.
Explanation:
The autonomic nervous system controls heart function to adapt to the effect of body positional changes. In some circumstances it takes a few seconds. So even if the passenger would have been held upright she would have recovered consciousness. The horizontal position sped up things
