Invertebrate doesn't posses "Backbone" whereas Vertebrate chordate have that. That's the only & most important difference between them.
Hope this helps!
The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
Answer:
Nucleation
Explanation:
The first step of formation of new phase, structure or self-assembly is called as Nucleation.
It is mentioned in the book of Molecular Biology of the Cell that whenever, In-vitro polymerization of micro-tubules and actin filament occur the first step is called nucleation. In other words Lag Phase.

If an area as a relatively large number of leaves, these leaves can block much-needed sunlight for other organisms, whether they remain on the tree of fall to the ground.
