The answer is C. That amino acids, fats, and nucleic acids might have formed in the waters of the past.
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.
Answer:
A dog breeder breeds a brown dog and a black dog and all the puppies are brown.
Explanation:
This is because of the Mendelian inheritance order of characteristics. In all other example, there are several other things that don't align with this order like gender variability, specie variability etc.
All the puppies are brown and this shows proper and complete dominance in accordance with the law...
Answer:
A dog breeder breeds a brown dog and a black dog and all the puppies are brown.
Explanation:
According to Mendel’s Law of Dominance, when two homozygous parents that have contrasting traits are crossed, the dominant trait is what would be expressed in the next generation as phenotype. The offspring produced by these parents are heterozygotes having two different alleles of a trait that are contrasting. One allele will be dominant over the other. The allele that is not expressed is the recessive allele of the trait, while the allele that is expressed is the dominant allele.
A good example of Mendel’s law of Dominance is the case of a dog breeder who breeds a brown dog and a black dog and all the puppies are brown.
We can infer that both parents are likely homozygous to hair/skin color as a trait. And when crossed, all offspring are brown simply because the allele for brown color is dominant over the allele for black color, and since the offspring are heterozygotes, i.e., they have a pair of dominant allele and recessive allele, the dominant allele would be expressed over the recessive allele. Black color is concealed in the presence of brown color.
b) desalination uses large amounts of energy.
c) desalination is the main process ised to provide water for crop irrigation
d) all of the above
The statement that is true about desalination is that desalination uses large amounts of energy, i.e., option b.
The process by which the dissolved mineral salts are removed from water is referred to as desalination.
The process that is applied to seawater is the most used one to obtain fresh water for human consumption or agricultural purposes.
It generally uses a large amount of energy as compared to other processes.
Thus, the correct option is b.

The event that characterizes the Paleozoic era is the Cambrian explosion, according to which a large number of biological class prevalent today are primitive of fish and corals that evolved during that era.
Further Explanation:
The Paleozoic Era is run from nearly five hundred forty-two million years ago to two hundred fifty-one million years ago; that was the time many changes occur on earth. This era starts with the breakdown of the supercontinent and the formation of a new one. In this era, many plants are developed and also very first animal (vertebrate) found on land. This era is divided into six different periods, namely:
After this, many Paleozoic seas found with blastoid and crinoid echinoderms, rugose corals, tabulate, graptolites, and articulate brachiopods. At the last phase of this era, glossopterids, cycads, ferns, and primitive conifers were present across many landscapes. The Paleozoic mass disappears at the late phase of Devonian and end phase of Ordovician. The end phase of this era is referred to as the Permian period.
