Answer:
1.One of the arctic willow's abilities is to produce a pesticide for itself to keep predators away. The plant adapted to the permafrost by growing shallow roots, not long roots, to keep from freezing itself over. Also, it grows close to the ground, to get out of the way of the wind.
2.In many natural areas that are considered grasslands, the reason trees do not grow is because the native wildlife kills the trees. ... Another factor is that the grass can be quite tall in grasslands and saplings die because they don't get enough sun.
Explanation:
Earthquakes and Volcanoes have higher concentrations at tectonic plate boundaries. The faults at convergent and divergent boundaries are going to have more seismic activity.
A covalent bond is also called a molecular bond. it’s the chemical bond that involved the sharing of electron pairs between the atoms.
Answer:
The metabolic chemical reaction is reversible, and they too would attain equilibrium if they take place in a test tube separately. However, if a cell attains metabolic equilibrium it is considered as dead. Thus, a cell in the body is not in equilibrium.
The spontaneous flow of substances within and outside of the cell prevents the metabolic pathways from attaining an equilibrium, and the cell persists to perform the work all through its life. This principle is demonstrated by the open hydroelectric system.
Answer: 1500kg/m^3
Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.
