In pheasants, there are three plumage variants: light, buff and ring.
the table below gives the results of several crosses between parents of unknown genotype.
use this information to answer questions 8-9 :

parents offspring male x female

1. light x light
2. light x buff
3. buff x light
4. light x ring
5. buff x buff

males all light ½ light, ½ buff ½ light, ½ buff all buff ½ buff, 1/4 light, 1/4 ring all ring
females all light ½ light, ½ buff ½ light, ½ buff all buff ½ buff, 1/4 light, 1/4 ring all ring 6. ring x ring

8. if you were to cross the male parent from family #6 with the female parent from family #3, what offspring ratio would you expect?

a) all buff

b) ½ light, ½ ring

c)% light, ½ buff

d)% buff, ½ ring

e) ½ buff, 1/4 light, 1/4 ring 9.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

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.
