1. Comets are cosmic snowballs of frozen rock and dust that orbit the Sun. When frozen, they are the
size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a
giant glowing head larger than most planets. The dust and gases form a
that stretches away from the
for millions of miles.
2. How long does it take the Comet Swift-Tuttle to orbit the Sun?
3. Halley's comet takes about
years to orbit the Sun. The next time Earth will be able to see it will be in
the year
Each time that Halley returns to the inner solar system its nucleus sprays ice and rock into
space. This debris stream results in two weak meteor showers each year, the Eta Aquarids in May and the Orionids in
October.

the answer is d (apex) good luck : ))

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

the titanic would be the correct answer
