Answer:

Answer to 1: a black hole is a tremendous amount of matter crammed into a very small (zero) amount of space. Answer to 2: the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer Answer to 3: <em><u>A black hole is a place in space where gravity pulls so much that even light can not get out.</u></em> The gravity is so strong because matter has been squeezed into a tiny space. because no light can get out, people can't see black holes Answer to 4: <u>stellar, intermediate, supermassive, and miniature.</u> Answer to 5: the asymmetry of bright and dark sections of the ring are caused by the Doppler effect as the matter is coming toward Earth (brighter) or receding (dimmer).

Saltwater fish constantly drink water but still excrete concentrated urine to compensate for the water loss. They also have gill
Dmitrij [34]

Answer:

The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.

Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.

In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.

In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
