Answer:
Explanation:
Mitochondria and Chloroplast contain some Ribosomes which are different from the cytoplasmic ribosomes,These were measured to be 80s,while the Mitochondria and Chloroplasts are 70s.
Furthermore smaller circular DNA were found in theses two organelles,(which are the first DNA outside nucleus).These DNA types are the exact forms found in bacteria.
Thus, it was concluded that if these organelles could contained these genetic materials,they must be bacterial.Therefore chloroplast and mitochondria were ancient bacterial which now live in a mutual exclusive relationships in the larger cells of Eukaryotas(plant and animals).This is the basis of Endosymbiont theory.
That is these organelles live inside(Endo) new host in symbiosis or beneficial association with one another (symbiont).
The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
The four mechanisms are as follows:
1) Orographic lifting: Air is forced to rise over a mountainous barrier
<span>
2) Frontal wedging: Warmer, less dense air is forced over cooler, denser air along a front
</span>
<span>3) Convergence: Pileup of horizontal air flow resulting in an upward flow
</span>
<span>4) Localized convective lifting: Unequal surface heating causes localized pockets of air to rise because of their buoyancy. </span><span />
Answer:
Explanation:
The cat and dog paws are adapted for walking, running, climbing and digging. Both the animals can use their front paws and back paws for different needs or just as the situation ahead of the demands.
Answer:
Archaea
Eubacteria
Explanation:
Both the kingdoms archaea and eubacteria comprise of prokaryotes yet there are some differences present between the two kingdoms.
The archaea have a distinct evolutionary history as compared to the eubacteria. The cell wall of archaea is made up of Pseudo-peptidoglycan where as the cell wall of eubacteria is made up of peptidoglycan or lipopolysaccharide. Interior membranes cannot be found in the archaea but are present in the eubacteria.
