D, all of the above. Your body sweats when it gets too hot to cool the body, and shivers when it gets too cold to heat the body. The nervous system is responsible for sensing everything in and around the body.
1. A cell
2. A eukaryotic cell
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Explanation:
We have the following data:
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
C. Asthma
- Goitre is due to lack of iodine in diet.
- Arthritis due to inflammation of the joints.
- Bone cancer due to radiation.
- Asthma due to intake of harmful gases like CO₂.
