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:
Total biomass is found by summing the dry mass biomass of all individuals in a given land area and then reported by naming the area of concern, e.g. biomass per plot, ecosystem, biome, classroom. To be able to compare biomass in different locations, scientists standardize biomass per unit of area

Answer:
a. cells with more than one nucleus.
Explanation:
Mitosis is a cell division which completes in two stages. The first stage is called karyokinesis in which one nucleus divides into two and the second stage is called cytokinesis in which division of the cytoplasm takes place. During mitosis, cytokinesis is followed by karyokinesis. If a cell begins to divide and the division ceases after karyokinesis then the cell will have more then one nuclei in the absence of cytokinesis. Each of the nuclei will have the same number of chromosomes.
A cell with more than one nucleus is called a multinucleated cell. For example, human bone cell has many nuclei.
