C why might it be important to move from non renewable resources to renewable resources
In the sentence "The F2 generation phenotypes resulting from the
monohybrid cross of purebreds display a ratio of _____" the word that
correctly completes the sentence is 3:1. In the monohybrid cross of
purebreds, F1 generation will consist of heterozygotes with dominant
phenotype. When F1 generation cross, the F2 generation phenotypes will
be as following: 3 dominant phenotypes (1 dominant homozygote and 2
heterozygotes) and 1 recessive phenotype (1 recessive homozygote).
<u>Answer</u>: d. it will release chemical messengers.
The action potential, which is an electric pulse, will travel down the axon untill it reaches the synapses. At the synapses, neurotransmitters (chemical messengers) will be released by the neuron.
I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
