Answer:
Heterozygous tall x homozygous short individuals
Explanation:
<em>The cross that could produce tall plant to short plant in the ratio 1:1 would be between a heterozygous tall and homozygous short individuals.</em>
Assuming the allele for tallness is represented by T and that for shortness is represented by t. TT and Tt individuals will be tall while tt individuals will be short. A cross between a heterozygous tall individual (Tt) and homozygous short individual (tt) will be such that:
Tt x tt
offspring: Tt (tall), Tt (tall), tt (short), and tt (short). <em>(see the attached image for the Punnet's square analysis)</em>
<em>The ratio of tall to short offspring = 1:1</em>
Hence, the cross is between heterozygous tall and homozygous short individuals.

Answer:
To make a positive change in the environment.
Explanation:
We have to Stimulate birds with 3 different beaks by feeding them fruit to stimulate a positive change in the environment because birds control insect and rodent in the environment that causes severe damage to crops. It also contributes to pollination, and seed dispersal which result in great benefits to people. Annually insects destroy hundreds of millions of dollars of agricultural and forest products so if we provide safe environment to the birds they can save our millions of dollars.
