Which of the following statements about homo erectus is false?
select one:
a. h. erectus was the first hominin to have a projecting nose with downward-pointing nostrils
b. some researchers believe that the h. erectus populations in east asia and africa should be classified as different species: h. erectus and h. ergaster
c. h. erectus had larger brow ridges than earlier hominins
d. from studies of its dental characteristics, h. erectus is thought to have been vegetarian

The false statement is option d.

Explanation:

The Homo erectus had exhibited some ape-like features, such as large teeth and heavy jaw. They used fire, and hunted and consumed cooked meat. On examining one came to know that the wear on the species teeth suggested a varied diet, which also comprised consumption of meat. It has been found that the female skeleton of H.erectus had shown some signs of hypervitaminosis, and the condition is most likely caused by the consumption of carnivore livers.

the match lol

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.
