A codon is a group of three mRNA bases while an anticodon is a group of three tRNA bases. For example AUC is a codon and UAG is an anticodon that matches it.
Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
The per capita ecological footprint is the total ecological footprint for a given country or area is false and is therefore denoted as option B.
<h3>What is Ecological footprint?</h3>
This is referred to as the amount of land which is required to ensure that there is adequate use and sustainability of the resources which are present in area at a given period of time.
The per capita ecological footprint is the average ecological footprint for a given country or area and not the total ecological footprint which is therefore the reason why false was chosen as the most appropriate choice.

Answer: Option A
Explanation:
Scientist used the domain Eukarya which comprises the togetherness of all the eukaryotic species. They have been put together because all of the eukaryotic species have their recent common ancestor as eukaryotes.
The first eukaryotic cells, which had nucleus originated 2 billion years ago which had organelles. They explain the endosymbiotic theory.Most of the eukaryotic species that have been evolved from this.
Eukaryotic species have been evolved from another eukaryotic species and share some similar characteristics.
