Answer:
Protein
Explanation:
Considering the wide diversity of life forms, the majority of the Scientific Community will consider protein molecule to be the more likely candidate for genetic material, despite Griffith's findings regarding the "transforming factor".
A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.
This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.
Answer:
three organisms battling over limited resources
Explanation:
It is limitted resources so there will be competition between the animals
It could be this one -
three organisms of the same species living in an area
BUT...
The other one says limitted resources.
the relationship between DNA, codons, amino acids, and proteins. During transcription, DNA is transcribed into messenger RNA when the the base codes in DNA are copied. mRNA serves as the code for assembling amino acids in a certain order.
Organic molecules, which are found mostly in food. These molecules have C-C or C-H bonds, which are high energy bonds.
