Answer: there is a continuous flow of electrons from water to NADPH.

Explanation:

In photossinthesis, Solar energy produces photochemical oxidation (electron output) of H20 (water) due to the existence of excellent electron donors and receptors, where their final receptor is NADP +, which is reduced to NADPH and O2 is released. Photosynthesis brings together two processes, the luminal reactions that occur when the plant is illuminated, and the obscure reactions of CO2 fixation (Calvin's cycle) that occur in both light and dark environments.

A portion of an mRNA attached to a ribosome reads: 5 GACCAUUUUUGA 3

aniked [119]

Answer:

a) phenylalanine

Explanation:

A triplet codon results into a particular amino acid. mRNA is read in 5' to 3' direction during translation. tRNA carrying an amino acid enters the A site first. Then a peptide bond is formed between the new and old amino acid. The polypeptide along with the tRNA moves to P site while the now empty old tRNA moves from P to E site and exits. Hence a tRNA is first in A site followed by P site and then finally E site.

Here, a tRNA with histidine amino acid is present in the P site. From the given sequence, only CAU codon can result into histidine. So if CAU region is present in P site that means that UUU will be present in A site. UUU codes for phenylalanine amino acid so the tRNA entering the A site will carry phenylalanine.

How could this statement be revised to make it a hypothesis? Fish meal is safer than artificial fertilizers, but it does not mak

Triss [41]

Just take out the fluff.

Plants that are fertilized with fish meal will be healthier for plants than the plants that receive artificial fertilizer.

Or make one of those If, Then, Because statements.

If a plant is fertilized with fish meal rather than artificial fertilizer, then the plants will be overall healthier because fish meal is natural compared to the artificial fertilizer.

In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.

Arte-miy333 [17]

Answer:

This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. Maternal DNA is inherited uninterrupted from generation to generation

Explanation:

The living consort of Queen of Elizabeth ,Prince Philip, is a grand nephew of Tsar Nicholas 11. 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.

The 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, 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.
