They use radiometry and pyrometry
NASA uses the Transiting Exoplanet Survey Satelite (TESS) telescope that employes this technology
This telescope measures the brightness/luminosity of stars. When this brightness drops regularly, every more or less in the same number of years, then there is the likelihood of a planet orbiting the star. The dip in brightness of the star is directly proportional to the size of the planet and the distance between the star and the orbiting planet.
Answer:
C. Its sex cells are haploid and a result of meiosis.
Explanation:
Just Took The Test
The scenario that might reverse the action of the pump when some organisms that normally live in pond water contain water pumps, If endocytosis happens then water molecules will move into the cell then ion/solute concentrations will be higher in the cell causing a hypotonic solution.
