The population age structure is is simply the structure of a population in a given time period by age groups. In order to represent the population age structure in a simple and efficient way, the population pyramid is used. Depending of what type of population is dominant, the pyramid will have different shapes. It can easily show us the trends and type of demographic transition for a particular population. When there high birthrates, the pyramid tends to be widest at the bottom, but when there's low birthrates the pyramid tends to be widening in the middle and upper sections.

Answer:
A fat molecule comprises of a glycerol backbone and three fatty acid tails.
The structure of phospholipids comprise of two fatty acid tails instead of three. The third carbon of the glycerol backbone is attached to a phosphate molecule. The phosphate molecule is absent in the structure of a fat molecule.
Both human and bacteria cells contain DNA and both have a outer membrane that controls how materials come into and leave the cell.
Predominantly multicellular not in bacteria but in human body
*Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body..
*DNA occurs in a circular form* in bacteria only..
* Ribosomes size in bacteria 70s and in human body 80s
*Capable of growth at temperatures greater than 80 C only in bacteria
*His tone proteins present in cell only in human body cells
* Operons present in DNA only in bacteria..
Yes, when two root tendrils from a strangler fig touch, they fuse together. Because the roots wrap around the trunk of the host tree, they overlap a lot and eventually form a mesh that completely encircles the host.
The “host” being a cypress tree.
