Answer:

Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.

Explanation:

A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.

Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.

zhenek [66]

Answer:

The hypertonic habitats is home to saline protists which depend on salts for their survival.

Explanation:

  • Protists are a multicellular organism like the algae, don't from natural groups have invertebrates. They freely occupy the environment that contains liquid water.
  • As these microorganisms cant breath in freshwaters the need the salts to sustain themselves and responsible for the production of 30% of oxygen in the water sphere.
  • Diatoms and other oozes are some of the most beautiful protists found to date, they are also home to corals and stick to the body of seafloors. As for long, they have adapted to the same type of conditions.
