Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Compare with mitosis.
Answer:
any time a source of energy is obtain using natural means, the 10 % rule will apply. 10 % rule means when energy is passed in an ecosystem from one trophic level to next, only 10% of the energy will be passed on. A trophic level is the position of organism in the food chain.
So Quaternary consumers are at the top position in the food chain, they will receive less energy from the food as compared to the primary consumers which are at the bottom of the food chain. so when getting less food and less energy, Because of this, the populations of Quaternary consumers are usually the smallest out of the populations in the food chain.
