Answer:
The finches on Galapagos Islands had different beak
The beaks of the finches changed over time
The Galapagos finches had a common ancestor
Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.
Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
Answer:
Explanation:
Knowing the value of G allows us to calculate the force of gravitational attraction between any two objects of known mass and known separation distance. As a first example, consider the following problem.
Continents are land masses that exist on the surface of the earth. The continents are part of the uppermost layer of the earth which is called the crust.
<span>B)The immunity they receive in the womb from their mother is temporary.
I believe this as the mother passes antibodies to the child through the last three months of pregnancy, and this is a passive immunity </span>
Not necessarily as many plants have double or quadruple the amount of their DNA each time they reproduce (polyploidy). This phenomenon doesn't in fact change them.
This best seen when you think about some diseases seen in humans like Down syndrome where there is an extra chromosome 21, but this addition (aneuploidy) did not add to the complexity
