Based on this information, it can be said that evolution of the frog's body is taking place through natural selection. This selection is based on how "fit" the frog is to his environment.
Answer:
mRNA or messenger RNA goes to ribosomes to dictate the genetic information that it contains .
Explanation:
Ribosomes act as work benches during protein biosynthesis.mRNA also called messenger RNA binds with the smaller subunit of ribosome at the time of translation.
The bound subunit of ribosome reads the genetic information as codons containing three concecuetive nucleotides present in mRNA thus helping tRNA to bring the particular amino acid specific for that codon at the A site or attachment site of ribosome.
Thereafter ribosome moves to the next codon to bring another amino acid and so forth.
Thus mRNA helps ribosome to brings the amino acids at the translation site.
Nucleic Acids:
- Uracil
- Adenine
- Guanine
- Cytosine
Explanation:
Since we only have one strand shown, I'm going to assume it is RNA. Both DNA and RNA have nucleic acids, but RNA has 1 different nucleic acid; it replaces Thymine with Uracil. So the 4 nucleic acids are uracil, adenine, guanine, and cytosine.
If the picture shown is a cross-section of DNA, then our 4 nucleic acids are adenine, thymine, guanine, and cytosine.
This is a result of classical conditioning in humans. Classical conditioning pairs two stimuli in eliciting a response; one stimulus is a normal stimulus (unconditioned stimulus) and another is a learned stimulus (conditioned stimulus).
In this case, humans normally salivate in response to eating; perhaps pizza from Pizza Hut from example. Food aromas and restaurant symbols do not normally elicit the response alone; but since the restaurant symbol and food aroma is paired with eating a pizza (which normally elicits the response), then the human will elicit the response in just seeing the logo of Pizza Hut and the smell of pizzas, without actually eating.
