The correct answer is - A. larger and more rounded.
The modern humans have brain that significantly differs in size, but also in shape, compared to the brains of the hominid ancestors. The brain of the modern humans is larger, by far, and also it is more rounded and better developed, which has also led to the bone structure of the head to be more rounded. The brains of the hominid ancestors were smaller, but also more flattened, which can also be easily seen by the structure of the skull, more elongated and flattened.
It has differences between one ancestor and another, because as the evolution was going, every next ancestor in the line had slightly larger and slightly more rounded brain, so the difference is bigger with the older ancestors, and smaller with the more recent ones.
Answer:
Transporta sodio y potasio a través de la membrana celular.
Explicación:
La bomba de Na + / K + también conocida como -ATPasa, que es una bomba de proteínas que está presente en la membrana celular de las neuronas y las células animales. Es responsable del transporte de iones de sodio y potasio a través de la membrana celular. La bomba de Na / K es responsable del movimiento de los iones de potasio hacia la célula mientras que, por otro lado, mueve los iones de sodio fuera de la célula. Esta bomba de Na + / K + es responsable de varias funciones en la estructura física de las células.
Answer:
The tRNA would be unable to read the mRNA CODON, and will be unable to carry its corresponding amino acid
Explanation:
Protein synthesis occurs in two major stages; transcription and translation. Transcription involves the synthesis of a mRNA molecule while translation involves reading the sequence of the mRNA in order to synthesize amino acids that forms protein. Let's look at translation in details. Translation occurs with the help of a type of RNA molecule called transfer RNA (tRNA) present in the RIBOSOME (site of protein synthesis).
The tRNA possesses a group of three nucleotides called ANTICODON, which it uses to read the mRNA codon that is complementary to it i.e. an anticodon UAC will read mRNA codon AUG. The tRNA binds to the mRNA molecule in order to assess its nuceleotide sequence. Once, a complementary anticodon succesfully reads a particular mRNA codon, it carries the amino acid encoded by the mRNA codon it reads to the growing polypeptide chain. This is the normal translation process.
However, as stated in the question, that if a wrong anticidon successfully binds to a codon. This means that the anticodon that binds to the mRNA codon is not complementary to it. What would happen in this case is that the Anticodon will be unable to read that particular codon it binds to because the complementary base pairing rule is used to read i.e. A-U, G-C. Once, the anticodon cannot read the mRNA codon, the tRNA will also be unable to carry the amino acid that is encoded by that CODON.
An interpreter is someone who translate a language into english or more understanding language. Meaning a person who translates words for you. Example: I was at a meeting an a interpreter came to translate the meeting for this deaf lady.
Answer:
A strain is a genetic variant or subtype of a microorganism (e.g., virus or bacterium or fungus). Microbial strains can also be differentiated by their genetic makeup using metagenomic methods to maximize resolution within species. This has become a valuable tool to analyze the microbiome.
I hope it helps.
Have a great day.
