Let's call the colour alleles C for dominant purple, and c for recessive white.
We have crossed Cc with Cc. So if we put that in a Punnett square, we'd have a CC, two Cc and a cc. That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
Answer:
make me brainliest pls :)
Explanation:
Insulin suppresses hepatic glucose output and adipose tissue lipolysis, lowering blood glucose and fatty acid levels. It also increases hepatic lipid synthesis for subsequent storage in adipose tissue and stimulates glucose uptake into fat and muscle.

Overproduction - An organism gives birth to too many children
Genetic Variation - The offspring each have genetic differences in appearance, behavior, etc
Struggle to Survive - Offspring must fight in order to gain essential resources (food, water, mates, etc)
Successful Reproduction - Organism produces offspring with beneficial adaptations that aid in survival
