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
The answer to your question is a
Meiosis produces four genetically different haploid cells.
Answer:
B. decreases salivation and increases blood pressure
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.
The sympathetic nervous system is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.
Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.
The control of salivary production by the sympathetic nervous system leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.
