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.
A and b are cells so they definitely are not bacterium so c and d are bacterium I think. Your welcom.
Epididymis would be the correct answer, can i get brainliest please
This is because of natural selection; since polar bears live in a rough environment, natural selection gives them more fur, more muscle, and can go longer without food
Answer:
The correct answer will be option-C.
Explanation:
Photosynthesis is a complex process which converts light energy into chemical energy which is used to form the glucose molecule. Photosynthesis occurs in two stages: light-dependent and light-independent reaction.
The light-dependent reaction is the reaction which takes place in the sunlight and converts light energy to chemical energy in ATP and NADPH molecules.
The light-dependent begins when photosystem absorbs light energy which causes the excitation of the electrons provided by chlorophyll molecule. The excited electrons get accepted by electron acceptor molecule and a chain of electron flow begins called electron transport chain.
This creates a scarcity of electron in photosystem which causes hydrolysis of the water molecule as a result oxygen gas is released. The electron flow leads to the synthesis of ATP molecules through chemiosmosis.
Thus, Option-C is the correct answer.
