How do nerve cells form different types of tissues?
a.
a group of these cells perform similar functions and become nerve tissue after information in the dna of the nucleus tells the nerve cells to develop and perform special functions.
b.
a group of these cells perform similar functions and become nerve systems after information in the rna of the nucleus tells nerve tissues how to develop and to perform special functions.
c.
a group of these cells perform similar functions and become nerve tissue after messages from the brain tell nerve cells how to develop and perform special functions.
d.
a group of these tissues perform similar functions and become nerve organs after messages from the heart tell nerve cells to develop and perform special functions.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
