A question is something someone asks. A hypothesis is like a person's theory.
The answer is A. I think because that how it shows
Yeah yeah so :D,
Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.
So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)
the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.
Answer:
This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. <u>Maternal DNA is inherited uninterrupted from generation to generation
</u>
Explanation:
The living consort of Queen of Elizabeth ,Prince Philip, <u>is a grand nephew of Tsar Nicholas 11.</u> They shared the same maternal ancestry.
Therefore, his mitochondrial must be maternal, and compatible with that of the Tsar Nicholar. Male children always inherit maternal mitochondria (mtDNA)and passed from generations to generation.
T<u>he blood samples of prince Philip can be taken, to extract the mtDNA,and matched with the sample of mtDNA obtained from the exhumed bodies of the Tsars,</u><u> </u>to reaffirmed the compatibility of the ancestry .
If sample of the compatible mtDNA, from price Phillip was compared with the mtDNA of the woman who claimed to be Anastasia, her claim can be validated.
Matched sample shows she was the daughter, while negative result proves otherwise.
