Answer:
They measure the shift in a star's emission spectrum.
Explanation:
Exoplanets are planets found outside the solar system.
Planets orbiting far enough from stars to be resolved reflect very little starlight, so planets are detected through their thermal emission instead. These thermal emission is gotten by observing the shift in the stars emission spectrum.
Coronagraphs are also used to block light from the star which results to leaving the planet visible. Direct imaging of an Earth-like exoplanet requires extreme use of optothermal stability.
They can also be found by using space based telescopes.
Answer:
Explanation:
Bilateral symmetry is a type of body symmetry where the body is divided in to halves i.e refers to organisms that have body shapes which look like mirror images along the midline which is called the sagittal plane.
Hypoventilation is a process where little amount of air enter into the alveoli which result in a decrease in the amount of oxygen in the lungs and increase in carbondioxide produced by the lungs. It is caused by too shallow breathing or slow breathing.
Hemothorax is a condition where there is blood build up in the pleural space or chest wall and lungs.
