In dogs, black coat color is dominant over chocolate (brown) coat color, and short hair is dominant over long hair. Two dihybrid dogs (heterozygous for both traits) are crossed. Complete a Punnett square for this cross and answer the following question 1. What are the phenotypes of the parents?
2. What are the genotypes of the parents?
3. What percentage of the puppies will be black and short haired?
4. What percentage of the puppies will be chocolate and short haired?
5. What percentage of the puppies will be black and long haired?
6. What percentage of the puppies will be chocolate and long haired?

Interpreting as: chocolate

Assuming "chocolate" is a food

Assuming milk chocolate

Assuming any type of milk chocolate

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
