First choice.
You can refer to any bio book to simply give you a brief summary for what each organ do and what juices each organ produce to digest what specific typr of material in your food.
Answer:
Is the correlation among stimulus (one natural and another from the environment).
Explanation:
Ivan Pavlov, worked with dogs. He was testing a learning path in the area of conduct ism.
1.- First he tried a bell (this is the environment stimulus) to feed dogs (salivation is the natural stimulus).
2.- By passing the time, the reinforcement of the environmental stimulus make that the dogs start salivation just by the sound of the bell, does not matter if they have food or not.
3.- In this way he probed that learning is based in following and repeating some conducts.
Explanation:
Template: T, A, C, G
Pairing: T- A, A-T, C-G, G-C
Answer: adenine, thymine, guanine, cytosine
Further explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.
Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.
DNA stores all of an organism’s genetic information. Its molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule ;
- cytosine and thymine are formed from pyrimidines- N at position 1 and 3 of a fused ring;
- Guanine and adenine are formed from organic compounds called purines (pyramidines fused to another organic ring of imidazole)
- Each base pair contains a purine and pyrimidine joined via hydrogen bonding e.g. A-T & G-C and are called base complements.
In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.
