Peter and rosemary discovered a natural ecosystem with an extreme climate, oscillating between cycles of intense drought and abundant rainfall, as well as an uncontaminated area that had never been explored by humans. This was an excellent location to study the evolution of Galapagos finches.
- For their outstanding long-term studies showing evolution in action in Galápagos finches, Peter and Rosemary Grant are renowned.
- They have shown that natural selection is responsible for the incredibly quick changes in body and beak size in response to variations in the availability of food.
- Due to the lack of predators or rivals for the finches, Daphne Major makes an excellent location for research.
- (The cactus finch is the only other finch on the island.)
- The weather, and consequently the availability of food, has a significant impact on the medium ground finch's capacity to survive.

Answer:
Explanation:
Soils provide plants with essential minerals and nutrients. Soils provide air for gaseous exchange between roots and atmosphere. Soils protect plants from erosion and other destructive physical, biological and chemical activity. Soils hold water (moisture) and maintain adequate aeration. And conspiracy theorist astronaut dose not believe that the moon or air exists lol hope this helps
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.
Answer:
C
Explanation:
If you have more than one variable then you wont know which variable caused the change. Hope this helped, if it did give it a thanks or whatever.
