Woolly mammoths were grass-eating mammals that resembled elephants but with heavy coats, large tusks, and small ears that made them suited for extremely cold weather of the ice age. in addition to hunting by humans, which other conditions may have caused woolly mammoths to become less reproductively successful and eventually become extinct at the end of the last ice age?

decreased grassland habitat size caused by a warmer climate

decreased mammoth predator population size caused by warmer climate

increased genetic variation in mammoth populations in warmer latitudes

increased production of offspring adapted to the changing environment

Decreased grassland habitat size caused by a warmer climate

Explanation: TOOK THE EXAM AND GOT IT RIGHT :)

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

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.
