Biology

PilotLPTM [1.2K]3 years ago
8 0

Answer:

 Elliptical galaxies, such as M87  have very little gas and dust. ... Both the largest and the smallest known galaxies are elliptical. Very large elliptical galaxies can reach 300 million light years in diameter. Dwarf ellipticals, which are very common, may contain only 1/100,000th as many stars as the Milky Way!

 Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

Eukaryotes represents the domain of life. Domain Eukarya are classified into four kingdoms they are protista, fungi, plantae and animalia.

The kingdom protista represents the organisms that are simple structured and they swim through the water and obtain nutrients from the environment.

In the kingdom fungi like mushrooms absorb nutrients from the environment and they are heterotrophs.

In the plantae kingdom the organisms are plants and they are autotrophs. They prepare their own food.

In Animalia kingdom the organisms are animals and they are multicellular heterotrophs. They do not have cell walls and the reproduction is done sexually and some can reproduce asexual.
