What technology are scientists using to search for other planets? How are they using this technology to identify other planets?
Anni [7]

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.

Further microscopic analysis of negatively stained specimens reveals a colorless ring around each of the spherical cells against
Tanya [424]

Answer:

b. a capsule

Explanation:

The capsule is mainly made up of polysaccharides and surrounds many bacteria. Capsule staining includes mixing of the bacterial cells with dye and spread out in a thin film on a slide. After air-drying, the cells appear as light-colored structures present in a relatively dark blue-black background. This occurs since the dye particles cannot penetrate either the cell or its capsule. Therefore, the given slide with a colorless ring around the cells in a dark background represents the presence of a capsule around the observed cells.
