Materials eliciting increased tongue flicking and prey attack in garter snakes were isolated from both earthworm and fish prey. New extraction methods based on chloroform-methanol mixtures are valuable adjuncts to the more typical aqueous preparations. Both high- and low-molecular weight components from earthworms and fish were active. The similarity between the active chemicals in these two classes of prey was established using several methods of analysis.
Answer:
1) Nitrogenous bases
2) Nucleotides
3) Purines
4) Pyrimidines
Explanation:
1) Each one is made up of a pentose , a group, and one of four Nitrogenous bases
2) Adenine, guanine, cytosine and thymine are Nucleotides
3. Adenine and guanine, which have a nine-member double-ring, are called Purines
4. Cytosine and thymine, which have a six-member single-ring, are called Pyrimidines
Answer:
25%
Explanation:
Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
