Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers

750

Explanation:

Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.

Let's say R = red and r = white.

The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr

The punnet square for the second generation is:

               R          r

  R        RR       Rr

  r         Rr         rr

We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
