Which of these defines the term phenotype (with reference to a gene's alleles)?
the genetic code of an organism (i. e. both of its
alleles)
the actual appearance or characteristics of an
individual organism (ie the effect of its allele
combination)
a situation where two equally dominant alleles
produce a phenotype that combines both
characteristics (eg, blood type ab)
two or more alternative forms of a gene

Phenotype is : The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).

Explanation:

We come across differences shown by   individuals of same  species or we can say dis-similarity shown by offspring when compared to his/her parents .

When we cross parental generation , the gamete formation occur in accordance with Law of Segregation and then we get to see different combination of gametes that give rise to offspring with contrasting characters (In accordance with Law of independent assortment ).

After crossing we make conclusions by calculating the phenotypic and genotypic ratio of the cross .

Phenotype : It refers to physical expression of an organism or  The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).

Phenotypic ratio of Monohybrid cross is always 3:1 .

Genotype : Refers to genetic constitution of an organism .

Genotypic ratio of Monohybrid cross is always 1:2:1 .

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them  

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
