NEED HELP WITH THESE 4 QUESTIONS WILL GIVE BRAINLIST!!! 1.What were some characteristics that the finches developed to give them an advantage in surviving?

2.How do you think that the one species of finch evolved into many different species, each with its own advantages?

3. In what ways do these advantages help the finches to survive and reproduce?

4. What might have happened if the finches didn't evolve into many different species?

1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection

3.  Medium ground finches with larger beaks could take advantage of alternate food

4. three species of Darwin's tree finches have been known to inhabit Floreana  but no birds singing that song on Floreana have been heard in many years.

Explanation:

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
