This shows that these organelles were once free-living organisms with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.
Answer:
The Inter-Tropical Convergence Zone (ITCZ)region gets the most direct sunlight at any given period in time. This in turn causes air to be unstable with a drop in pressure and rise of air which cools and condenses into clouds to form precipitation causing the wet season in the tropics.
In this region, the sun is directly or almost overhead as seen during summer periods in the tropics.
Only in areas of the North and South of the ITCZ known as doldrums which at times are parallel to the ITCZ do we have high pressure that aren't conducive to precipitation causing dry season in the tropics.
In the ITCZ zone, we also have the tropical rain forests along the equator with huge amount of all round rain for the year.
Along the equator, on either side of the rain forests we have the dry and wet forests with the savannah to the North of this region and the southern hemisphere to the south of these forests since these forests are seen mostly in the ITCZ than the savannahs.
Rain shadows and ocean cueeebts may at times cause some savannahs to be along the equator and some rain forests -wet and dry forests- to be positioned further form the equator.
Answer:
Antibodies
Explanation:
Bordetella pertussis is an obligate human pathogen and is the etiological agent of whooping cough. It is known to be an opportunistic organism.
The pathogenic mechanism of Bordetella pertussis is also known as virulence factor. These virulence factors are known to include adhesins such as filamentous haemagglutinin, fimbriae and pertactin, which allow B. pertussis to bind to ciliated epithelial cells in the upper respiratory tract.
It is known to be the agent of whooping cough, a highly contagious respiratory disease, dramatic for infants and also for elderly and pregnant women.
In this case, the antibodies will be the response that is uniquely directed against the organism. It is said earlier that this organism is an opportunistic one, this means that it causes infection when the immunity is down. So, when the immunity is empowered , it will definitely fight against the organism
