Apea plant that comes from a line of true breeding tall plants is crossed with a dwarf pea plant. what are the phenotypes and genotypes of the f1 generation?

All F1 progeny will be heterozygous(Tt) for tall character.  

Explanation:

Ifpea plant that comes from a line of true-breeding tall plants than the genotype of the plant would be TT and when this plant is crossed with dwarf plant who have genotype tt for height trait then all the progeny will be tall phenotypically because all the phenotype would be heterozygous.

                             T       T

                       t   Tt      Tt

                       t    Tt       Tt

So the genotype of all F1 generation offspring would be Tt and phenotype would be tall because all have one dominant allele of tall character.

littering streams           is the answer

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.
