In a cross of heterozygous rw four o'clock plants (rw x rw) what proportion of the seeds will grow to produce pink flowers?
a.) 0
b.) 0.25
c.) 0.5
d.) 0.75

In this question, the parental is heterozygous i.e. RW

Parent:       RW x RW

Gametes:   R and W

F1:   RR ; RW ; RW ; WW

RR is red

WW is white

RW is pink

As you can see, 50% of the F1 generation is having pink flowers. So the answer is 0.5.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
