The correct answer for both blanks is "Sodium".
Sodium ions are necessary in small quantities for some sorts of flora, but sodium as a nutrient is extra usually wanted in large quantities by using animals, due to their use of it for era of nerve impulses and for upkeep of electrolyte balance and fluid stability. In animals, sodium ions are vital for the aforementioned capabilities and for coronary heart hobby and sure metabolic functions.
Answer: Wind currents can affect the weather.
Explanation:
One effect of wind currents has to do with the weather, as the wind travels over water it collects moisture, the vapor in the air then condenses as it reaches colder climates and generally causes heavy rainfall.
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
In order for you to enjoy the smell of a flower, molecules called <u>Odorants </u>from the flower must land on your olfactory epithelium, which lines the inside of the nose.
- When a person breathes in air containing odor molecules, the molecules attach to receptors in the nose and send signals to the brain.
- Odorants interact with primary epithelium olfactory receptors. Olfactory receptors, a type of epithelial cell with cilia, are found in the olfactory epithelium. These receptors receive the sense of smell, which is then sent to the brain.
- The sensory neuron connected to the receptor is activated when an odorant connects with a receptor that detects it.
- Only olfactory stimulus directly communicates with the cerebral cortex; all other sensory information is sent through the thalamus.
- Additionally, it has been suggested that the nasal mucus plays a role in the process of emulsifying hydrophobic odorant molecules, delivering them to receptor sites.
