How are computers used in producing weather forecasts? check all that apply. - they compile data from multiple instruments. - they collect air temperature and air pressure data. - they eliminate the need for human meteorologists. - they transmit data on developing weather systems from space. - they use mathematical equations to show what will happen to the atmosphere if conditions change.

-They compile data from multiple instruments.  

- They use mathematical equations to show what will happen to the atmosphere if conditions change.

The weather forecast agencies or institutions use supercomputers which can retain the data obtained from the satellites, radar, weather balloons, anemometer (wind speed measuring device) and from other instruments to give an appropriate information about the present or future weather conditions.

The computers can be used to solve the make the appropriate mathematical equation related to the atmospheric changes by applying various software tools which includes log function and statistics.

Explanation:

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

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.
