Answer:
The correct options are: A "
vestigial wings, red eyes" and D "full wings, purple eyes"
Explanation:
female parent: vg+pr+/vg pr
(phenotype - full winged and red eyes)
male parent: vgpr/vgpr
(phenotype - vestigial winged and purple eyes)
Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.
Canada, one of the wealthiest countries in the world, is also one of the most water-rich. The province of Ontario shares the Great Lakes—which contain 18 percent of the world’s fresh surface water—with the United States. Access to sufficient, affordable, and safe drinking water and adequate sanitation is easy for most Canadians. But this is not true for many First Nations indigenous persons. In stark contrast, the water supplied to many First Nations communities on lands known as reserves is contaminated, hard to access, or at risk due to faulty treatment systems. The government regulates water quality for off-reserve communities, but has no binding regulations for water on First Nations reserves.
The options attached to the above question are given below:
A) The boys at first were very polite about my medals and asked me what I had done to get them.
B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.
C) after that their manner change a little toward me although I was their friend against Outsiders
D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.
E) I had been wounded it was true but we all knew being wounded after all was really an accident.
ANSWER
The correct option is D.
In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
According to this dichotomous key, any catfish must be leathery, that is, without scales. They have a flattened body, as in most fish with benthic habits, that is, they live at the bottom of the waters. Coloration varies from bluish gray to yellow. It can reach 1 meter in length and weigh about 5 kilos.
<h3>What is catfish?</h3>
Catfish and catfish are common designations given to fish of the order Siluriformes in most of South America.About 2,200 species of these fish are known, classified into almost 40 families (only two, Ariidae and Plotosidae, have marine species). They are found almost all over the world, but more than half of the known species are native to South America.
With this information, we can conclude that the catfish (Ictaluruspunctatus) is a representative fish of the order Siluriformes, family Ictaluridae, characterized by not having scales.
