Answer:
With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude. On top of Mount Everest, which is the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level.
Answer:
Trichomoniasis
Explanation:
Trichomoniasis is an sexually transmitted disease that affects around 30% of world population. The common symptoms are frequent urge to urinate, vaginal bleeding, burning sensation during urination.
The causative agent of trichomoniasis is a protozoa called <em>Trichomonas vaginalis</em>. This protozoan can be transfer through the genital contact. The protozoa can easily be transfer from affected individual to the healthy individual.
Thus, the correct answer is option (3).
Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
D it’s the brain of the cell
