3 0

Answer:

An organism would need a 4 chambered heart.

Explanation:

The heart consists of 4 chambers in which blood flows freely.  Right atrium, left atrium, left ventricle and right ventricle.

The pulmonary arteries carry de-oxygenated blood to the lungs  from where CO2 is released and O2 is picked up during the process of respiration. The pulmonary vein then takes the oxygenated blood to the left atrium of the heart and then to the left ventricle of the heart.

In Griffith's experiments with Streptococcus pneumoniae, rough nonencapsulated streptococci were converted into smooth encapsula
larisa86 [58]

Answer:

The correct answer is - transformation.

Explanation:

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.

This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.

He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.

Thus, the correct answer - transformation.

What do we mean when we say that the genetic code is degenerate?A single codon can encode more than one amino acid.An amino acid
Arada [10]

Answer:

An amino acid can be encoded by more than one codon.

Explanation:

Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.

Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.

Translation occurs in which part of the cell?
Elza [17]

Explanation:

Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
